JAVA FULL STACK DEVELOPMENT

It is almost impossible to create a full-fledged software product using only one technology. This usually involves complete tech stacks – Standard combinations of tools and programming languages. As all software products consist of the client side and a server, there are usually two separate stacks that cover each of the layers. However, there are approaches that can be used to build web or mobile application from A to Z. These are called full stack development.

Accordingly, a generalist that has broad skills across all aspects of product engineering is usually called a full stack developer.

Being considered unicorns due to their rare expertise and versatility, they are in high demand for large companies and startups alike, from Facebook and eBay to Munchery, Betterment or Tinder.

As an idea of a person equally proficient at HTML/CSS, Python, and SQL has become more of a myth, the approach towards acquiring new skills and learning quickly has led to the appearance of specialists strong in one particular stack. Let’s see what the most popular stacks are and how they’re used.

When talking about full stack JavaScript the first thing that comes to mind is the MEAN stack. It is a technology bundle that includes MongoDB, Express, AngularJS, and Node.js.

However, with the rapid growth of this approach, more alternative options for full stack JavaScript development are added. While server-side JavaScript programming with Node.js and Express web framework is the most common technology choice, other Node.js-based tools, such as Meteor, Sails.js, Koa, restify or Keystone.js, might be used as well.

The choice of possible frameworks for the front-end JavaScript is even greater. Aside from traditional AngularJS or AngularJS 2.0 frameworks, numerous libraries, such as React, Vue.js, Knockout.js, or Backbone.js, are typically used, depending on the project specifics.

As for the database, almost any MongoDB alternative can be used: MySQL, PostgreSQL, Apache CouchDB or Apache Cassandra.

The Pros of Full Stack JavaScript Development

The fact that companies like Groupon, Airbnb, Netflix, Medium and PayPal adopted the full stack JavaScript approach to build some of their products speaks for itself. However, small start-ups seem to enjoy using it as well. This is mostly due to the number of benefits full stack programming offers.

Common language, better team efficiency with less resources

Having all parts of your web application written in JavaScript allows for better understanding of the source code within the team. Therefore, there is no such thing as a gap between front and back end engineering that occurs when two teams are working separately using different technologies. Moreover, you can now work with only one team instead of two, for back and front end, which should significantly reduce the cost and effort of finding and retaining the right talent. Such a cross-functional team is a great asset when following Agile methodologies.

(*) Extensive code reuse

With full stack JavaScript, you save time through code reuse and sharing. Following the “don’t repeat yourself” (DRY) principle, you might be able to reduce the effort by reusing the parts of the code (or sharing libraries, templates, and models) on both back and front end that are very close in terms of logic and implementation. In other words, you don’t need to think about the Java-script utility equivalents in Python or Ruby, you just use the same utility on the server and in the browser. Reducing the number of lines of code by up to 40 percent is also a valuable capability when refactoring and maintaining the source code.

(*) High performance and speed

Node.js uses event-driven, non-blocking IO model that makes it lightweight and fast as compared to other commonly used back end technologies. To prove this, PayPal published a comprehensive report on the results they have seen in the process of migrating from Java to full stack JavaScript. The company was able to make the development almost 2 times faster while reducing the engineering personnel involved. Moreover, they have seen a dramatic improvement in performance, doubling the number of requests completed per second and decreasing the average response time by 35 percent for the same page. This means that the pages are served 200ms faster, which is definitely a noteworthy result.

(*) Extensive knowledge base

Backed by giants like Facebook and Google, JavaScript has a powerful and fast-growing community. Based on the Stack Overflow survey from 2016 quoted above, the language tops the list of the most popular technologies on the website with 62,588 votes. The website currently lists 1,543,025 questions tagged “JavaScript”, which indicates the high activity of the developer community and the huge amount of valuable information that can be found there.

(*) Free & open source toolset

Most of the full stack JavaScript development tools are free or open source projects. This means you don’t need to bear additional expenses for costly licenses or subscriptions. The tools that are open sourced are updated regularly and evolving fast due to the active community contributions. Instead of relying on a fixed set of technologies, you may use any of more than 475,000 tools (which have doubled since last year), hosted by the npm, the largest JavaScript modules registry in the world.

The Cons of Full Stack JavaScript Approach

Yet, no technology is perfect. Despite all the benefits the full stack approach offers, there is always some drawbacks to be aware of.

(*) Insufficiency with computation-heavy back end

When it comes to heavy computation and data processing on the server side, Node.js is not the best option. There are lots of far better technologies to handle projects like machine learning, algorithms, or heavy mathematical calculations. Having a single CPU core and only one thread, that processes one request at a time, it might be easily blocked by a single computationally intensive task. While the thread is busy processing the numbers, your application won’t be able to work with other requests, which might result in serious delays. Yet, there are numerous ways to overcome this limitation. By simply creating child processes or breaking complex tasks into smaller independent microservices, that use more suitable technologies and communicate with your back end, you can handle complex computational tasks in Node.js.

Relatively young technologies

When compared with PHP or Java, server-side JavaScript has been around for a shorter period of time. This results in a smaller knowledge base and limited integration capabilities. As an example, some developers cite the immaturity of the connections between Node.js and relational database tools, such as MySQL, Microsoft SQL Server, and PostgreSQL.

(*) Jack of all trades, master of none?

It is a common belief that a developer can truly master only one area of knowledge. With every other skill gained the quality of his/her expertise will decline. While syntax and grammar of JavaScript are mostly the same on client and server side, there are still many details to consider. Aside from being proficient in front end development, full stack JavaScript developers need to have an expertise in back end programming, such as HTTP protocol, asynchronous I/O, data storage fundamentals, cookies, etc. That is why some say that there are really no full stack engineers: Every one of them is either front or back end oriented. However, we have all the reasons to disagree, based on our own experience and strong JavaScript skills.

Drawbacks of every separate tool in the stack combined

As every technology stack, MEAN combines the weak sides of all 4 its elements. Most of them are minor technical limitations, which appear under certain circumstance. However, in order to use the stack, it’s important to realize possible bottlenecks of every tool and adjust your development strategy accordingly.

Agile Software Development Life Cycle

As inventive technology emerge and competitive pressure increases, companies must change the way they do business and embrace digital transformation.

Low-code development is transforming the way companies build, deploy and manage applications to help them achieve their digitalization goals.

SDLC is simply consists of all the steps that go into building and maintaining any software.

Like most SDLC models, the Agile model also follows the basic steps of the SDLC, with some variations and uniqueness.

Agile is a broad project management methodology that focuses on involving the customer in every step of the development process.

The Agile approach breaks down the entire project into smaller development cycles called iterations or sprints.

In the Agile methodology, for every iteration, you develop a specific version of the working software. This is called the increment.

At the end of the iteration, the customer reviews the increment and gives their feedback, which is incorporated in the next iteration. The cycle continues until the software is fully developed, giving the customers exactly what they want.

With the Agile method, your software will be exactly how your customers would need it to be.

Iterative: the cycle is repeated until you get the desired result

Incremental: every cycle has something more advanced to offer (the increment)

The Agile SDLC model is executed and repeated at every iteration (generally, the entire software development lifecycle lasts for only about a month) until you get the final product.

Requirement analysis: incorporates the suggestions received at the end of the previous iteration

Design: the feedback is kept in mind while designing the upcoming increment

Coding and developing: the developers work to build the increment (which includes only some features) rather than building the entire software in one go

Testing: the testers design and execute test plans according to the increment

Deployment: the operation team deploys the newly developed version

Maintenance: the new software version is monitored by the operation team to ensure things are working smoothly before starting on the next iteration

Big Data Management System

If there is successful business today, it’s the successful understanding, use & strategy of company’s data. Understanding of data & determining it is the whole big question for user & stakeholders. How much is the data? How it can be stored? How accurate is the data? Is the data best fit for my problem.

Answer to these questions aren’t solve on one door step but we can find way to organise, find solution to solve the questions of our client. We Whizian find solution for our valuable clients. We will be going through basic & important terminologies known Data Management & Data governance.

Data management is best seen as an IT program, whose goal is to organize and control your data resources so that it is accessible, reliable, and timely whenever users call on it.

Viewed from this administrative perspective, the IT teams responsible for data management may rely on a comprehensive, customized collection of practices, theories, processes, and systems – an entire suite of tools – that collect, validate, store, organize, protect, process, and otherwise maintain data. After all, if data isn’t treated appropriately, the data can become corrupt or unusable, becoming completely useless.

Importantly, data management encompasses the entire lifecycle of a data asset, from the very initial creation of the data to the final retirement of the data.

Data management can include many related fields and categories, including any of the following as relevant to your company:

Data governance and data stewardship

Data architecture

Data quality management

Data warehousing

Business intelligence and analytics

Metadata management

Data security management

Data Governance (Business Strategy):- If data management is logistic then data governance is the strategy.

Data governance should feel bigger and more holistic than data management because it is: as an important business program, governance requires policy, best reached by consensus across the company.

The purpose of data governance is to provide tangible answers to how a company can determine and prioritize the financial benefits of data while mitigating the business risks of poor data. Data governance requires determining what data can be used in what scenarios – which requires determining exactly what acceptable data is: what is data, where is it collected and used, how accurate must it be, which rules must it follow, who is involved in various parts of data?

Importantly, data governance must go beyond IT and include stakeholders from across the enterprise. In order to ensure the safety, reliability, and trustworthiness of all data, governance requires that stakeholders from all business areas be involved. Consider the alternative: if each business silo approaches their data strategy differently, the end result is chaotic and, likely, not comprehensive enough to be useful.

Determining your data governance can include a wide range of processes, practices, and theories. It is likely to overlap with many data areas, like security, compliance, privacy, usability and integration. The end result may be some system that determines the decision rights and accountably of processes and individuals, like which data processes are used when, and which people can take certain actions under specific circumstances.

The ultimate goal is to determine a holistic way to control data assets, so that the company can get the absolute most value from the data.

A good way to determine data governance? It is not defined by technology. Instead, technology should support data governance through automation, scaling, and augmentation.

Data governance starts as a theory (or several), but it can become tangible through the creation of the following:

Data quality definitions, which determines the condition of the data, as well as its trustworthiness and adherence to data policies

A business glossary, which records the meaning of all data, ensuring clarity and preventing unnecessary repetition

Roles and responsibilities, which provides an organizational structure to who cares for and maintains which data

Governed data catalog, which serves to locate and facilitate understanding of the data. More advanced catalog may even group data into various related collections, based on how previous users have accessed the data, which can provide additional meaning and insight and organization.

Metadata creation, which links technical processes to specific data implementation, as well as anything that produces, uses, or influences data. This can even track the “lineage” of data, or the relationships of data across different sections, such as data within similar meanings, business processes data, and data specific to departments, business units, applications, other products, and even internal or external geographies.

Many experts in data governance also recommend a way for data systems to be organized to promote active participation from company employees, for instance. This may allow users to indicate when data is incorrect or fix it directly, which promotes both better-quality data but also trust that the data is strong and accurate.

Benefits of data governance

Once your data management processes are established, data governance is a logical next step because of the many benefits such guidance can provide, including:

Increasing the value of your company’s data

Decreasing costs within other subsets of data management, by knowing what you’ll focus on and what you’re choosing to skip

Increasing enterprise revenue overall

Standardizing data systems, policies, and procedures

Ensuring correct regulation and compliance procedures

Helping to solve issues with data

Promoting transparency

Establishing training and education around data

Data management and data governance are not the same things, in concept or in practice, but they are both essential to ensure the successful and valuable use of data in your company.

Backend Technology

Back-end development is the esoteric and are the whole and sole of any web or mobile app development.

So as a business enterprise, thinking of digitizing your company without backend support is simply not possible. Back-end is a vast sea of technical coding and this is not for the faint-hearted.

There are in numerous server-side scripting languages effective in reaching the end goal. The server-side programming language you select depend on the preferences of your development team and the project requirements such as your database/operating system setup. Being aware of what each server-side scripting language can offer what is unique is deciding your backend technology, and whom to hire for these tasks.

Component Or We can say heart of Server Side(Backend Technology)

The back end is made up of three parts: the server, the database, APIs, and a back-end web application written using server-side languages.

*   Server: It is a computer that runs back-end software built using server-side languages.

*    Database: It stores and manages your application’s data

*    API: It communicates between server and database.

             For instance, if a user is updating a password on web application, the server-side scripts will collect the information the user enters, the application will process that information on the back-end server, then will interact with the database to update that information.

             The backend web developers use server-side scripting language to develop back-end application and this language in turn communicates between user, server, and database. Anything that is explicitly written goes into the text mark-up of a website which is the front-end or back-end software.

               When user request an Edit, delete and update (For Example, the fields in menus, photos, or user passwords) in database, they are delivered via server-side scripts that create a channel between server and a user. In the browser, front end scripts like JavaScript, Angular, react make that information available to the user.

FUNDAMENTALS Of SERVER-SIDE SCRIPTS

They run on a server, embedded in the site’s code

*Runs on-call. When specific feature of site is “called up” or “posted back” to the server, server-side scripts are the one which send request to server, process and return requested data.

*Designed to interact with back-end permanent storage, like databases, and process information from the server to access the database like a direct line from user to database

*Provides the data transfers from server to browser, bringing pages to life in the browser, e.g., processing and then delivering a field that a user requests or submits in a form

*Powers the dynamic web application with functions such a user validation, saving and data retrieval, navigation between web pages

*Play an immense role on how a database is built from the initial setup and evolved upwards

*Build application programming interfaces (APIs) that can be used to control data and software with numerous apps.

SERVER-SIDE CODE AND DATABASES

* Server-side scripting processes are what the user can view through the server, to locate a particular book, chapter, page, or a particular sentence and sending back the required information back to browser in a smooth, fast and seamless way.

* This is possible because of the server-side programming languages and middle ware your back-end developer codes to create a customized path from site to database. Information for your site resides on the server until it’s requested, which makes your site both fast and secure.

Popularly Trending server-side languages Whiz Works on

1) PHP: The most popular server-side language on the web, PHP is designed to extract and edit information in the database. It’s encompasses databases written in the SQL language. PHP was designed strictly for the web and is the most widely used languages. Ease to install and deploy, is what it making competitive with in numerous modern frameworks, and is the foundation for a number of content-management systems. PHP-powered sites: WordPress, Wikipedia, Facebook

2) Python: Due to its flexibility of less lines of code, the Python programming language is fast, making its way into the market. The emphasis is on readability and simplicity, which makes it easy to learn for beginners. It’s one of the oldest scripting languages, powerful, and works well in object-oriented designs. Python-powered sites: YouTube, Google, The Washington Post

3) Java: A subset of the C language, Java comes with a huge base of add-on software components. At its core, Java is a variation of C++ with an easier learning curve additionally it is platform independent, thanks to the Java Virtual Machine. The motto “Compile once, run anywhere” augur well for enterprise-level applications, high-traffic sites, and Android apps. Java sites: Twitter, Verizon, AT&T, Sales-force

AND THEIR SERVER-SIDE FRAMEWORKS

* Django: This Python framework was developed to implement a fast-paced development environment. Django sites: Pinterest, Nasa, Pitchfork

* Node.js: JavaScript is typically a front-end script, but with the Node.js framework, and can be used in server-side technology, from APIs to entire stacks. Its core unique selling point is handling client-server communication—its fast, doesn’t block, and is ideal for real-time apps like chat rooms, data-heavy applications, and any software that requires the streaming of fresh content, like a news feed. Node.js sites: Dow Jones, PayPal, LinkedIn

Whizian Back-end developers are involved in constructing the actual logic on which an application or a website works. Some of the key skills they should have include: an in-depth knowledge of the back-end programming language/framework, accessibility and security compliance, a basic understanding of front-end web technologies like HTML, CSS and the ability to manage a hosting environment. Backend developer worker work on development languages, Database & Cache, server, API (REST & SOAP) etc.

WEB FRONT END DEVELOPMENT

Everything that you see when you’re navigating around the Internet, from fonts and colours to dropdown menus and sliders, is a combination of HTML, CSS, and JavaScript being controlled by your computer’s browser.

As we have seen All that we see, click and interact on a website is because of front end development.  A site is loaded in a browser from the server in front-end development.  A user sends request to the server. The server sends the response back to the user.  This framework is known as client server framework. Client server frameworks use languages JavaScript, ReactJS and AngularJS. These frameworks have made interactive and mobile responsive websites possible for the users. Let’s have an insight to the Front-End Web Development.

The Client Server Framework

The client is the browser a user uses to view a website using mobile devices, laptops, or desktop computers. The server is stationed at a remote location, running the website’s back-end architecture processing.  Conceptually client-side scripting is done by the web browser, and server-side scripting is done by the web server.

Client-side scripting is always evolving becoming simple, lively and more user-friendly.  Client-side scripts run in the browser and processes requests without call-backs to the server.

Server-side scripting is the back-end web development and main function of it is to connect your website’s database to the browser and bring back a page to your screen providing a smooth user- experience. Server-side scripts process the data, and then update the website. For example, populating drop-down menus, loading products to a page, updating a user profile, and more.

Front-End Web Development

Your website comprises of a sum of layers – structure, data design, content and functionality. All that you click, interact, and customize on a website is because of front-end development.  This user facing functionality is developed by front-end developer. The front-end developer uses a combination of client-side scripts and frameworks, mark-up languages, and designs an environment where a user can experience an aura of content, layout and interaction.

In short front-end development is a powerhouse where creativity and innovation collide.  Front end developers need to be a bridge between the designer and the back-end programmer.

The front-end developer creates interaction and user experience with scripts embedded in a website’s HTML. Everything you as a visitor to your website sees, click, or uses to input or retrieve information is the work of the front-end developer. They are the ones who create client-side software that brings the site’s design to life. Scripts are downloaded by the browser, processed, and then run apart from the server. In front development the main focus of the front-end developer would be on user experience, and the technology they implement will determine how well it accomplishes that speed, efficiency, and smooth functionality.

Skill Sets for Front-End Development

The core technologies of front-end development are mix of HTML, CSS, and client-side scripts namely Javascript.

The core competencies in hiring a front-end developer, lies in his ability to have a broad view of how the front end of the site works and its design.  Added crossover knowledge of SQL, Java, PHP, Ruby, Node.js would be of great advantage to your front-end developer.

The main services of front-end developer include:

•Customize user experience

•Bringing life to designer’s concept with HTML, CSS, and Javascript

•Production, modification, and maintenance of websites and web application user interfaces

•Tool creation enhancing how users see and interact with your site in browser

•Implementing responsive design for mobile sites

•Contributing some back-end experience, collaborating on APIs

•Consulting on best SEO practices

•Testing the site during development for usability and fixing any bugs

Front-End Languages

Since now you might have a brief overview of front-end technology. Let’s have a look at some of the most widely used scripting languages and front-end frameworks. The front-end languages are almost always used in the context of their frameworks, which make quick work of complicated code with libraries of pre-packaged, shareable code, and lots of add-ons. Your front-end developer may use one or a combination of these when during building the front end of your web site.

Front-End Frameworks

Front-End framework facilitates a rapid development with libraries of pre-packed, shareable code and software add-ons.  Some of the popular Java script frameworks are listed below. Your front-end developer can use one or combination of these when building front end for a website.

•Angular JS – This framework and other JS frameworks like Backbone.js, power up the power of Javascript.

•jQuery – This is a fast, small, JS object library, it streamlines how JavaScript behaves across different browsers.

•Bootstrap – This leading mobile-first framework blends HTML, CSS, and JavaScript to influence rapid responsive app development. With Bootstrap, your web site will be compatible with all modern browsers and is screen responsive on any size screen, from tablets to phones to laptops.

Client-Side scripting Development

A path breaking that has changed the hard-and-fast rules for client side vs. server side is the AJAX technology. The old standard was that server-side processing and page post-backs were used when the browser needed to interact with things on the server, like databases. AJAX, with its asynchronous calls to the server, can pull the data instantly and efficiently, without requiring a post-back.

Another major boost is jQuery technology, a fast, small, and feature-rich JavaScript library with an easy-to-use API that works across a multitude of browsers. Like code libraries do, jQuery changed the way that millions of people write JavaScript, simplifying a number of other client-side scripts like AJAX at the same time.

Technology is ever-changing and evolving, it’s crucial to know who to follow in order to get the best advice, tips, and news.  We at WHIZ have a compiled a list of the top front-end developers to deliver excellence. At WHIZ, we have a team of multi-talented and top front-end developers having extensive knowledge and experience in field. Therefore, creating website for your business requirements at our place would be highly competitive and worthwhile.

Mobile Application Development

The world of mobile apps has shown amazing innovations in the past few years. From top-notch technologies like Beacon, M-commerce, Cloud computing, Internet of Things, etc., to proficient gadgets like Apple Watch, Google Glass, and other wearables, the mobile-era still evolves every now and then. Today, the smart device is an indispensable tool and helps us perform almost every day-to-day activity. Whiz Work on various technologies such as React Native, Ionic to deal with challenging & demanding world.

Your Mobile App will be fast! But not always that fast.

Application development using React Native:- React Native is known to have exceptionally fast speeds. But because it uses JavaScript, the speeds are lacking compared to native. JavaScript is not top tier when it comes to calculation-intensive tasks. Expect occasional slowdown when controlling native elements and utilizing complex logic. Facebook has even admitted that they “are not all the way there” in terms of optimization. There will be times that mobile application development will be slowed by the need to manually intervene and handle performance bugs. Consider React Native for Your Mobile Application Development Project. There are not many platforms that offer the same ease of use that React Native does. The system feels like developing for the web, yet it produces full fledge native apps. The process of producing an application can be smooth and efficient. The open source framework brings the best parts of React JS into the realm of mobile. So far, more than 650 people have volunteered to commit code to the React Native codebase. More than 50% of the code contributed to the codebase so far has been made by non-Facebook employees. mobile application development on this framework is picking up as this ecosystem quickly grows in abundance.

Application Development using Ionic :- Hybrid apps are a blend, hence the name hybrid, of both native and web solutions. Where the core of the application is written using web technologies. In this article we dive deep into hybrid app technology. When beginning to choose your solution to create a new mobile application, you are often faced with a wide range of options, but are unsure of where to begin. Is building your application solely with native solutions the right choice? Should your team look at only developing with web technologies? What about some of the hybrid solutions out there? These are among the many questions that arise when deliberating which path is best for your business.

To start the process, it’s important to remember that picking the right solution for your next application (or first) depends on several factors: Your budget, the timeline, your team’s experience with the technology and, finally, your target audience.

So, with that, let’s explore the three primary genres of mobile application development and discuss some of the benefits and drawbacks of each of these solutions. By the end of the article, you should have a better grasp of the choices and be able to find the right solution to your mobile application development goals. First, let’s define what our genres are.

What is a Native Mobile App?

When people speak of a native mobile application, they are usually referring to an application that has been written using the native development language and tools specific to that platform. For example: A native iOS application would be written in either Swift or Objective-C and compiled using Xcode, while a native Android application would have been developed using Kotlin or Java and compiled using Android Studio.

Since these applications are developed using the platform’s default solutions, developers have full and easier access to the device’s capabilities; like all the device’s sensors, the user’s address book, and whatever the latest and greatest new bit of technology the phone offers. Native applications tend to also be more performant since their code is closer to the ‘metal’. In addition to being faster, you will also have access to all of the native user interface (UI) controls and layouts. While you will probably want to style them to fit your applications’ theme, you will also want them to behave and interact like any other UI element on that platform.

However, any application written for iOS using Swift cannot run on Android, and vice versa. Meaning, you have to develop specifically for each platform, which can lead to a larger budget and team size, assuming that you’d want to release your application for both iOS and Android. In addition, your application is only available through each platform’s app stores, subjecting it to their respective rules and restrictions. This means for every release, whether it is a new feature or a bug fix, the same approval process must occur. This can take anywhere from a day to two weeks for the Apple App Store.

Hybrid Mobile App

This solution is a blend, hence the name hybrid, of both native and web solutions. Where the core of the application is written using web technologies (HTML, CSS, and JavaScript), which are then encapsulated within a native application. Through the use of plugins, these applications can have full access to the mobile device’s features. To better understand this approach, let’s break down how it all fits together.

The heart of a hybrid-mobile application is still just an application that is written with HTML, CSS, and JavaScript. However, instead of the app being shown within the user’s browser, it is run from within a native application and its own embedded browser, which is essentially invisible to the user. For example, an iOS application would use the WKWebView to display our application, while on Android it would use the WebView element to do the same function.

This code is then embedded into a native application wrapper using a solution like Apache Cordova (also known as PhoneGap) or Ionic’s Capacitor. These solutions create a native shell application that is just the platform’s webview component in which it will load your web application. This gives you the ability to create and publish true native applications that can be submitted to each of the platform’s app stores for sale.

Additionally, both Cordova and Capacitor have a plugin system that allows you to extend beyond the limitations of the ‘browser’ and access the full suite of capabilities of a user’s mobile device. So, if you wanted to use TouchID on an iOS device as a login option, or wanted to connect to a Bluetooth device, this can be easily done by installing a plugin. These plugins are created by a wide range of developers and many are actively supported. Ionic even offers a complete ecosystem of supported plugins as part of its Enterprise solution. So, the limitations of a web-only application are easily overcome, allowing your application to have parity with native applications in their features.

However, there are some drawbacks with this option. Similarly, to the web-only application solution, the UI library has to be recreated. Here is where solutions like Ionic, NativeScript, Xamarin, React Native, and others step in. These options all provide robust UI components that look and feel like their native counterparts, giving you a full suite of building blocks for your application.

The only other consideration to take into account is if your application is still running within the device’s native browser. If so, you may encounter performance issues or other quirks specific to each platform or operating version.

Final Thought Of Mind

So, what is the right choice for your application? Unless you are creating a highly performant game or other similar application, hybrid application development might be the right choice because it offers an easier development approach, cost savings, and compatibility across a variety of platforms. While they do require a bit more understanding to mesh the solution together, as well as the use of a UI library to assist in the proper presentation of your user interface, those challenges are known and can be easily solved with the right framework, like Ionic. Mobile apps don’t have to take a team of engineers to produce. Though not a “write once, run anywhere” solution, a single senior developer can head your mobile application development. With JavaScript and minimal traditional native development experience, you can produce a smaller mobile app that functions as well as one written using native frameworks. The framework isn’t perfect, so weigh these pros and cons when considering the best framework for your mobile application development

CLOUD COMPUTING & SECURITY

Although the adoption of cloud services is becoming increasingly popular in the past few years, many organizations are still sceptical of migrating to the cloud due to security concerns. This outlook tends to emerge from a lack of exposure to the emerging potentialities of the modern cloud. However, the case has become precisely opposite—firms, no matter how small or large, can benefit immensely from cloud migration when regarding stronger security and compliances.

Cloud providers reassure organizations of seamless and hassle-free cloud migration and ongoing maintenance; they make the security and protection of third party data their priority because their reputation highly depends on the kinds of services they provide. Once this goodwill suffers a blow, their company sustains a considerable loss, which is certainly not favoured.

The cloud providers render security with the help of following measures:

Safekeeping the Data Cloud providers are not just any organizations; they have grown considerably and have become among the wealthiest companies in the world. Security concerns come to them not as a challenge, but rather as an opportunity. These companies have a highly skilled team of professional IT engineers that are capable of tackling any security danger that may occur. Take for instance the most prominent cloud provider—Amazon. Amazon’s security parameters are well above the average reach of hackers. Amazon and other cloud providers take protecting infrastructure and customer data as their top priority. They apply a significant portion of their budget to meet and often go beyond security expectations. Companies such as Amazon go through a series of exercises that ensure the protection of physical infrastructure and systems.

Shared Responsibility Model A model that is implemented at the organizational level is the Shared Responsibility Model in which a cloud infrastructure provider is responsible for maintaining the physical security of its data centre, including building access, network and server hardware, as well as monitoring the hypervisor in charge of the virtual machines. On the other hand, the customer is responsible for securing operating systems, applications, and data running on cloud accounts. This co-operation is established when both sides are happy and comply willingly. The benefit is mutual & thus this model is generally upheld. With its implementation, the cloud providers render best practices for controlling access and limiting network exposures which result in a secured infrastructure.

Supply of Personalized Tools Typically, cloud providers supply tools that complement cloud-based security management tools to help the organization defend their virtual environments. Take, for instance, Amazon Web Services (AWS) CloudTrail; it provides visibility into the actions being taken by both legitimate users and bad actors operating in the cloud environment and acts as an active vigilante for the entire operation. Other security tools such as firewalls, file integrity monitoring solutions, and centralized logging also remain functional and works together in conjuncture with cloud tools. Thus, it all adds further layers of security that are purposefully built for strengthening and monitoring the environment.

Besides security measures, cloud computing is also highly compliant with the modern day needs of an organization. They focus on cost-effectiveness and the ease of use while keeping in mind the procurement of untainted security measures.

Reduced Business Expenditure From its advent, cloud computing engineers have strived to seek the betterment of the existing platform services. The financial aspect in organizations is of great importance to the engineers too. Therefore, a traceable shift can be seen in cloud computing as far as reducing cost is concerned. Cloud computing is much more affordable than a traditional data centre as it works on a pay-as-you-go model. The building, maintenance and retrieval of data in conventional terms is costly and messy as opposed to cloud computing. Cloud computing uses real-time extraction that takes seconds to locate the data, while any modifications can be done without any harm to the existing data. The labour-force employed and time consumed in cloud computing is a lot less than traditional data centres which result in a more cost-efficient solution for the business.

Greater flexibility Cloud computing enables organizations to become more agile and flexible through a variety of benefits. The cloud allows businesses to expand their infrastructure without any evident disturbance elastically. Organizations can instantaneously start using systems and applications on newly acquired cloud space without having to worry about the organizational insecurity. Instead, the human resource can work on their business strategies. Even for the IT professionals, who manage these clouds, their efforts can be oriented to other more strategic initiatives instead of a web of data complexity.

QUALITY ASSURANCE COMPANY

Quality assurance encompasses the processes and procedures that systematically monitor different aspects of a service or facility. It involves planning, fulfilling, and monitoring activities. Software testing in IT companies is a process of verification and validation. To testing software, QA engineers should know software or application that is needed to be tested. He should know the expected results to verify and validate testing results. All Manual and automation testing services:

1. Functional Testing Services:-

Functional testing is a kind of black-box testing that is performed to confirm that the functionality of an application or system is behaving as expected.

2. Alpha Testing

    It is the most common type of testing used in the Software industry. The objective of this testing is to identify all possible issues or defects before releasing it into the market or to the user.

 Alpha Testing is carried out at the end of the software development phase but before the Beta Testing. Still, minor design changes may be made as a result of such testing.

3. Alpha Testing is conducted at the developer’s site. An in-house virtual user environment can be created for this type of testing.

4.  Acceptance Testing

An Acceptance Test is performed by the client and verifies whether the end to end the flow of the system is as per the business requirements or not and if it is as per the needs of the end-user. This is also called User Acceptance Testing (UAT).

5.  Ad-hoc Testing

The name itself suggests that this testing is performed on an Ad-hoc basis i.e. with no reference to the test case and also without any plan or documentation in place for such type of testing.

Ad-hoc Testing is an informal way of finding defects and can be performed by anyone in the project. It is difficult to identify defects without a test case but sometimes it is possible that defects found during ad-hoc testing might not have been identified using existing test cases.

6. Beta Testing

Beta Testing is a formal type of Software Testing which is carried out by the customer. It is performed in the Real Environment before releasing the product to the market for the actual end-users.

7.  Back-end Testing

Whenever an input or data is entered on front-end application, it stores in the database and the testing of such a database is known as Database Testing or Backend Testing.

In Back-end Testing GUI is not involved, testers are directly connected to the database with proper access and testers can easily verify data by running a few queries on the database.

8. Browser Compatibility Testing

Browser Compatibility Testing is performed for web applications and it ensures that the software can run with the combination of different the browser and operating system. This type of testing also validates whether web the application runs on all versions of all browsers or not.

9. Backward Compatibility Testing

It is a type of testing which validates whether the newly developed software or updates the software works well with the older version of the environment or not.

10.  Black Box Testing

Internal system design is not considered in this type of testing. Tests are based on the requirements and functionality.

11.  Boundary Value Testing

This type of testing checks the behavior of the application at the boundary level.

Boundary Value Testing is performed for checking if defects exist at boundary values.

If testing requires a test range of numbers from 1 to 500 then Boundary Value Testing is performed on values at 0, 1, 2, 499, 500 and 501.

12.  Branch Testing

It is a type of White box Testing and is carried out during Unit Testing. Branch Testing, the name itself suggests that the code is tested thoroughly by traversing at every branch.

13.   Comparison Testing

Comparison of a product’s strength and weaknesses with its previous versions or other similar products are termed as Comparison Testing.

14.   Compatibility Testing

Compatibility testing ensures that software can run on a different configuration, different database, different browsers, and their versions. Compatibility testing is performed by the testing team.

15.  Component Testing

It is mostly performed by developers after the completion of unit testing. Component Testing involves testing multiple functionalities as a single code and its objective is to identify if any defect exists after connecting those multiple functionalities with each other.

16.   End-to-End Testing

Similar to system testing End-to-End Testing involves testing of a complete application environment in a situation that mimics real-world use, such as interacting with a database, using network communications, or interacting with other hardware, applications, or systems if appropriate.

17.  Equivalence Partitioning

The aim of this testing is to remove redundant test cases within a specific group which generates the same output but not any defect.

Suppose, the application accepts values between -10 to +10 so using equivalence partitioning the values picked up for testing are zero, one positive value, one negative value. So the Equivalence Partitioning for this testing is  -10 to -1, 0, and 1 to 10.

18.  Example Testing

It means real-time testing. Example Testing includes the real-time scenario, it also involves the scenarios based on the experience of the testers.

19.  Exploratory Testing

Exploratory Testing is informal testing performed by the testing team. The objective of this testing is to explore the application and looking for defects that exist in the application. Sometimes it may happen that during this testing major defect discovered can even cause a system failure.

20.  Functional Testing

This type of testing ignores the internal parts and focuses only on the output to check if it is as per the requirement or not. It is a Black-box type testing geared to the functional requirements of an application.

21.  Graphical User Interface (GUI) Testing

The objective of this GUI Testing is to validate the GUI as per the business requirement. The expected GUI of the application is mentioned in the Detailed Design Document and GUI mockup screens.

22.     Gorilla Testing

Gorilla Testing is a testing type performed by a tester and sometimes by the developer as well. In Gorilla Testing, one module or the functionality in the module is tested thoroughly and heavily. The objective of this testing is to check the robustness of the application.

23.  Happy Path Testing

The objective of Happy Path Testing is to test an application successfully on a positive flow. It does not look for negative or error conditions. The focus is only on the valid and positive inputs through which application generates the expected output.

24.   Incremental Integration Testing

Incremental Integration Testing is a Bottom-up approach for testing i.e continuous testing of an application when new functionality is added. Application functionality and modules should be independent enough to test separately. This is done by programmers or by testers.

25.   Install/Uninstall Testing

Installation and Uninstallation Testing is done on full, partial, or upgrade install/uninstall processes on different operating systems under different hardware or software environment.

26.   Integration Testing

Testing of all integrated modules to verify the combined functionality after integration is termed as Integration Testing.

Modules are typically code modules, individual applications, client and server applications on a network, etc. This type of testing is especially relevant to client/server and distributed systems.

27.  Load Testing

It is a type of Non-Functional Testing and the objective of Load Testing is to check how much load or maximum workload a system can handle without any performance degradation.

Load Testing helps to find the maximum capacity of the system under specific load and any issues that cause software performance degradation. Load testing is performed using tools like JMeter, LoadRunner, WebLoad, Silk performer, etc.

28.  Monkey Testing

Monkey Testing is carried out by a tester assuming that if the monkey uses the application then how random input, values will be entered by the Monkey without any knowledge or understanding of the application.

29.  Mutation Testing

Mutation Testing is a type of white box testing in which the source code of one of the program is changed and verifies whether the existing test cases can identify these defects in the system.

30.  Negative Testing

Testers having the mindset of “attitude to break” and using Negative Testing they validate that if system or application breaks. A Negative Testing technique is performed using incorrect data, invalid data, or input. It validates that if the system throws an error of invalid input and behaves as expected.

31.   Non-Functional Testing

It is a type of testing for which every organization having a separate team which usually called as Non-Functional Test (NFT) team or Performance team.

Non-Functional Testing involves testing of non-functional requirements such as Load Testing, Stress Testing, Security, Volume, Recovery Testing, etc. The objective of NFT testing is to ensure whether the response time of software or application is quick enough as per the business requirement.

It should not take much time to load any page or system and should sustain during peak load.

32.   Performance Testing

This term is often used interchangeably with ‘stress’ and ‘load’ testing. Performance Testing is done to check whether the system meets the performance requirements. Different performance and load tools are used to do this testing.

33.   Recovery Testing

It is a type of testing which validates how well the application or system recovers from crashes or disasters.

Recovery Testing determines if the system is able to continue the operation after a disaster. Assume that the application is receiving data through the network cable and suddenly that network cable has been unplugged.

Sometime later, plug the network cable; then the system should start receiving data from where it lost the connection due to the network cable unplugged.

34.   Regression Testing

Testing an application as a whole for the modification in any module or functionality is termed as Regression Testing. It is difficult to cover all the system in Regression Testing, so typically Automation Testing Tools are used for these types of testing.

35.   Risk-Based Testing (RBT)

In Risk-Based Testing, the functionalities or requirements are tested based on their priority. Risk-Based Testing includes testing of highly critical functionality, which has the highest impact on business and in which the probability of failure is very high.

36.  Sanity Testing

Sanity Testing is done to determine if a new software version is performing well enough to accept it for a major testing effort or not. If an application is crashing for the initial use then the system is not stable enough for further testing. Hence a build or an application is assigned to fix it.

37.   Security Testing

It is a type of testing performed by a special team of testers. A system can be penetrated by any hacking way.

Security Testing is done to check how the software or application or website is secure from internal and external threats. This testing includes how much software is secure from the malicious program, viruses and how secure and strong the authorization and authentication processes are. It also checks how software behaves for any hackers attack and malicious programs and how software is maintained for data security after such a hacker attack.

38.  Smoke Testing

Whenever a new build is provided by the development team then the Software Testing team validates the build and ensures that no major issue exists.

The testing team ensures that the build is stable and a detailed level of testing is carried out further. Smoke Testing checks that no show stopper defect exists in the build which will prevent the testing team to test the application in detail.

39.  Static Testing

Static Testing is a type of testing which is executed without any code. The execution is performed on the documentation during the testing phase.

It involves reviews, walkthrough, and inspection of the deliverables of the project. Static Testing does not execute the code instead of the code syntax, naming conventions are checked.

Static Testing is also applicable for test cases, test plans, design documents. It is necessary to perform static testing by the testing team as the defects identified during this type of testing are cost-effective from the project perspective.

40.  Stress Testing

This testing is done when a system is stressed beyond its specifications in order to check how and when it fails. This is performed under heavy load like putting a large number beyond storage capacity, complex database queries, continuous input to the system or database load.

41.   System Testing

Under the System Testing technique, the entire system is tested as per the requirements. It is a Black-box type Testing that is based on overall requirement specifications and covers all the combined parts of a system.

42.  Unit Testing

Testing of an individual software component or module is termed as Unit Testing. It is typically done by the programmer and not by testers, as it requires detailed knowledge of the internal program design and code. It may also require developing test driver modules or test harnesses.

43.  Usability Testing

Under Usability Testing, a User-friendliness check is done. The application flow is tested to know if a new user can understand the application easily or not, Proper help documented if a user gets stuck at any point. Basically, system navigation is checked in this testing.

44.  Vulnerability Testing

The testing which involves identifying weakness in the software, hardware, and the network is known as Vulnerability Testing. In malicious programs, the hacker can take control of the system, if it is vulnerable to such kind of attacks, viruses, and worms.

So it is necessary to check if those systems undergo Vulnerability Testing before production. It may identify critical defects, flaws in the security.

45.  Volume Testing

Volume Testing is a type of Non-Functional Testing performed by the Performance Testing team.

The software or application undergoes a huge amount of data and Volume Testing checks the system behavior and response time of the application when the system came across such a high volume of data. This high volume of data may impact the system’s performance and speed of the processing time.

46.  White Box Testing

White Box Testing is based on the knowledge about the internal logic of an application’s code.

It is also known as Glass box Testing. Internal software and code working should be known for performing this type of testing. Under these tests are based on the coverage of code statements, branches, paths, conditions, etc. We develop both standard web-based products and complex corporate software solutions.

JAVA FULL STACK DEVELOPMENT

It is almost impossible to create a full-fledged software product using only one technology. This usually involves complete tech stacks – Standard combinations of tools and programming languages. As all software products consist of the client side and a server, there are usually two separate stacks that cover each of the layers. However, there are approaches that can be used to build web or mobile application from A to Z. These are called full stack development.

Accordingly, a generalist that has broad skills across all aspects of product engineering is usually called a full stack developer.

Being considered unicorns due to their rare expertise and versatility, they are in high demand for large companies and startups alike, from Facebook and eBay to Munchery, Betterment or Tinder.

As an idea of a person equally proficient at HTML/CSS, Python, and SQL has become more of a myth, the approach towards acquiring new skills and learning quickly has led to the appearance of specialists strong in one particular stack. Let’s see what the most popular stacks are and how they’re used.

When talking about full stack JavaScript the first thing that comes to mind is the MEAN stack. It is a technology bundle that includes MongoDB, Express, AngularJS, and Node.js.

However, with the rapid growth of this approach, more alternative options for full stack JavaScript development are added. While server-side JavaScript programming with Node.js and Express web framework is the most common technology choice, other Node.js-based tools, such as Meteor, Sails.js, Koa, restify or Keystone.js, might be used as well.

The choice of possible frameworks for the front-end JavaScript is even greater. Aside from traditional AngularJS or AngularJS 2.0 frameworks, numerous libraries, such as React, Vue.js, Knockout.js, or Backbone.js, are typically used, depending on the project specifics.

As for the database, almost any MongoDB alternative can be used: MySQL, PostgreSQL, Apache CouchDB or Apache Cassandra.

The Pros of Full Stack JavaScript Development

The fact that companies like Groupon, Airbnb, Netflix, Medium and PayPal adopted the full stack JavaScript approach to build some of their products speaks for itself. However, small start-ups seem to enjoy using it as well. This is mostly due to the number of benefits full stack programming offers.

Common language, better team efficiency with less resources

Having all parts of your web application written in JavaScript allows for better understanding of the source code within the team. Therefore, there is no such thing as a gap between front and back end engineering that occurs when two teams are working separately using different technologies. Moreover, you can now work with only one team instead of two, for back and front end, which should significantly reduce the cost and effort of finding and retaining the right talent. Such a cross-functional team is a great asset when following Agile methodologies.

(*) Extensive code reuse

With full stack JavaScript, you save time through code reuse and sharing. Following the “don’t repeat yourself” (DRY) principle, you might be able to reduce the effort by reusing the parts of the code (or sharing libraries, templates, and models) on both back and front end that are very close in terms of logic and implementation. In other words, you don’t need to think about the Java-script utility equivalents in Python or Ruby, you just use the same utility on the server and in the browser. Reducing the number of lines of code by up to 40 percent is also a valuable capability when refactoring and maintaining the source code.

(*) High performance and speed

Node.js uses event-driven, non-blocking IO model that makes it lightweight and fast as compared to other commonly used back end technologies. To prove this, PayPal published a comprehensive report on the results they have seen in the process of migrating from Java to full stack JavaScript. The company was able to make the development almost 2 times faster while reducing the engineering personnel involved. Moreover, they have seen a dramatic improvement in performance, doubling the number of requests completed per second and decreasing the average response time by 35 percent for the same page. This means that the pages are served 200ms faster, which is definitely a noteworthy result.

(*) Extensive knowledge base

Backed by giants like Facebook and Google, JavaScript has a powerful and fast-growing community. Based on the Stack Overflow survey from 2016 quoted above, the language tops the list of the most popular technologies on the website with 62,588 votes. The website currently lists 1,543,025 questions tagged “JavaScript”, which indicates the high activity of the developer community and the huge amount of valuable information that can be found there.

(*) Free & open source toolset

Most of the full stack JavaScript development tools are free or open source projects. This means you don’t need to bear additional expenses for costly licenses or subscriptions. The tools that are open sourced are updated regularly and evolving fast due to the active community contributions. Instead of relying on a fixed set of technologies, you may use any of more than 475,000 tools (which have doubled since last year), hosted by the npm, the largest JavaScript modules registry in the world.

The Cons of Full Stack JavaScript Approach

Yet, no technology is perfect. Despite all the benefits the full stack approach offers, there is always some drawbacks to be aware of.

(*) Insufficiency with computation-heavy back end

When it comes to heavy computation and data processing on the server side, Node.js is not the best option. There are lots of far better technologies to handle projects like machine learning, algorithms, or heavy mathematical calculations. Having a single CPU core and only one thread, that processes one request at a time, it might be easily blocked by a single computationally intensive task. While the thread is busy processing the numbers, your application won’t be able to work with other requests, which might result in serious delays. Yet, there are numerous ways to overcome this limitation. By simply creating child processes or breaking complex tasks into smaller independent microservices, that use more suitable technologies and communicate with your back end, you can handle complex computational tasks in Node.js.

Relatively young technologies

When compared with PHP or Java, server-side JavaScript has been around for a shorter period of time. This results in a smaller knowledge base and limited integration capabilities. As an example, some developers cite the immaturity of the connections between Node.js and relational database tools, such as MySQL, Microsoft SQL Server, and PostgreSQL.

(*) Jack of all trades, master of none?

It is a common belief that a developer can truly master only one area of knowledge. With every other skill gained the quality of his/her expertise will decline. While syntax and grammar of JavaScript are mostly the same on client and server side, there are still many details to consider. Aside from being proficient in front end development, full stack JavaScript developers need to have an expertise in back end programming, such as HTTP protocol, asynchronous I/O, data storage fundamentals, cookies, etc. That is why some say that there are really no full stack engineers: Every one of them is either front or back end oriented. However, we have all the reasons to disagree, based on our own experience and strong JavaScript skills.

Drawbacks of every separate tool in the stack combined

As every technology stack, MEAN combines the weak sides of all 4 its elements. Most of them are minor technical limitations, which appear under certain circumstance. However, in order to use the stack, it’s important to realize possible bottlenecks of every tool and adjust your development strategy accordingly.

DATA SCIENCE & BUSINESS ANALYTICS

World roam around the data. While data analysts and data scientists both work with data, the main difference lies in what they do with it. Data analysts examine large data sets to identify trends, develop charts, and create visual presentations to help businesses make more strategic decisions. Data scientists, on the other hand, design and construct new processes for data modeling and production using prototypes, algorithms, predictive models, and custom analysis.

The responsibility of data analysts can vary across industries and companies, but fundamentally, data analysts utilize data to draw meaningful insights and solve problems. They analyze well-defined sets of data using an arsenal of different tools to answer tangible business needs: e.g. why sales dropped in a certain quarter, why a marketing campaign fared better in certain regions, how internal attrition affects revenue, etc.

Data analysts have a range of fields and titles, including (but not limited to) database analyst, business analyst, market research analyst, sales analyst, financial analyst, marketing analyst, advertising analyst, customer success analyst, operations analyst, pricing analyst, and international strategy analyst. The best data analysts have both technical expertise and the ability to communicate quantitative findings to non-technical colleagues or clients.

Data analysts can have a background in mathematics and statistics, or they can supplement a non-quantitative background by learning the tools needed to make decisions with numbers. Some data analysts choose to pursue an advanced degree, such as a master’s in analytics, in order to advance their careers.

Data scientists, on the other hand, estimate the unknown by asking questions, writing algorithms, and building statistical models. The main difference between a data analyst and a data scientist is heavy coding. Data scientists can arrange undefined sets of data using multiple tools at the same time, and build their own automation systems and frameworks.

A few decades ago, with the emergence of programming languages, we were able to create abstractions of real-life entities and allow computers to operate on those abstractions. Today, we are able to go further and create abstractions of decision-making processes. Closer the abstraction is to reality; more is the value created.

Breakthrough insights can be gained from data by asking the right questions, manipulating data sets and visualizing the findings in compelling ways. It’s the depth of data modelling that creates value for organizations that thrive for data driven decision making. The other source of value is collaborative decision making. When you have data models that fit closely to bring out important metrics, decision making becomes faster and accurate. It brings clarity to decide owners of key metrics without making assumptions.

If we take ecommerce organization’s as an example, typically the Chief Marketing Officer would own the KPI for driving traffic to the website. However, a closer look at the data would show that the main driver for traffic and engagement is the choice of brands within each category. CMO has very little control on this.

Apart from scientific governance, data can be leveraged for diverse applications such as:

Growth hacking – right data sets can be used to uncover commonalities between types of users that are either successful or unsuccessful with a product. It can also be used to formalize strategies to generate exponential traffic growth, while preserving traffic quality, and user loyalty.

Logistics – various types of data are collected at supply chain touch points such as customer information, the number and types of items, carrier data, delivery information, etc.  Data science can provide invaluable insights to optimize delivery routes, accurately forecast the supply and demand cycles, and lower the delivery costs.

Customer segmentation – customer data can be analyzed to identify the most and least profitable customers. Businesses can use this information to create customized offerings and services to drive optimum profit.

Review mining – customer reviews can be analyzed and converted to structured data to derive insights into what customers like, dislike and if they would recommend the product.

As many companies from MNC to start-ups have made way towards success using this giant technology. We Whizian are proud to be part of it.
