Module Layer: The core functionality of Magento is organized into modules, promoting code reusability and maintainability.

Presentation Layer: This layer deals with the appearance of the website and includes themes, layouts, and templates.

Service Layer: The service layer acts as an intermediary between the web server and the database, handling business logic and data manipulation.

Database Layer: Magento uses the EAV (Entity-Attribute-Value) database model, allowing for flexible and extensible data storage.

4. Magento Modules and Extensions

Magento’s modular architecture allows developers to create custom modules or integrate third-party extensions to add specific functionalities. Modules are self-contained units that can be enabled, disabled, or customized as needed. Popular extensions are available in the Magento Marketplace, providing solutions for various e-commerce requirements, such as payment gateways, shipping methods, and product enhancements.

5. Themes and Templates in Magento

7. Payment Gateways and Shipping Methods

Magento integrates with multiple payment gateways, enabling secure and seamless online transactions. Additionally, it supports various shipping methods, providing customers with flexible delivery options. Ensuring a smooth checkout process is essential for enhancing customer satisfaction and encouraging repeat business.

Security is of utmost importance for any e-commerce website. Magento incorporates robust security features, including data encryption, secure payment processing, and protection against common vulnerabilities. Regular updates and security patches are essential to keep the website secure and safeguard customer data.

Staying up-to-date with the latest Magento version is essential to access new features and security enhancements. However, upgrading requires careful planning and testing to prevent compatibility issues. Following best practices, such as using version control and staging environments, simplifies the upgrade process.

As with any complex system, issues may arise in Magento. Efficiently diagnosing and resolving problems is crucial to minimize downtime and maintain a positive user experience. Magento provides debugging tools and logs to help developers identify and fix issues effectively.

Entity Attribute Value (EAV) data model

Came across some articles on useful description and use case of EAV model in database.

https://en.wikipedia.org/wiki/Entity%E2%80%93attribute%E2%80%93value_model

https://inviqa.com/blog/understanding-eav-data-model-and-when-use-it

https://pbedn.github.io/post/2020-05-25-entity-attribute-value/

Basically the problem statement here is a number of different attributes can be used to describe an object, but only few attributes actually apply to each one. One option is to create a table with a column representing each attribute; this is suitable for objects with a fixed number of attributes, where all or most attributes have values for a most objects. However, in our case we would end up with records where majority of columns would be empty, because attributes may be unknown or inapplicable.

To solve the above problem we can apply the EAV (Entity-Attribute-Value) model. This pattern is also known under several alternative names including 'object-attribute-value' model and 'open schema'.

In the EAV data model only non-empty values are stored in database, where each attribute-value (or key-value) pair describes one attribute of a given entity. EAV tables are often characterized as 'long and skinny' where 'long' refers to multiple rows describing entity, and 'skinny' refers to the small number of columns used.

That’s the gist of it. Consider you are collecting a vast amount data (attribute/parameter) of an entity (in this case company). In this case, the datapoint can be designed in a similar fashion (along with metadata) and only applicable values are collected and stored in the underlying database. Here, you also have the flexibility to add any other new attribute without disturbing the existing table definitions and data, kind of a scalable model.

Indeed a good read !

A guide for launching your own online store

This is how it might look. If more collection has to be added, only the number of rows have to be increased. But if there are also other products to be considered, Let say a jeans also has to be added to the stock and its attributes also will be added. Considering this, several other products like skirts, trousers etc will be added. If the same approach is followed, this is how it will look.How you can choose the right software company for web application development

The present scenario has been tough for all businesses especially the retailers of non-essential items. People have been flooding the usual physical stores to get items for daily survival. Considering the new purchase behavior and preference it is obvious that retailers are involved in selling other products online.

Does that imply that these retail selling businesses have no future? Or they demand a change of strategy?

The answer to this question is switching to digitalization and embracing the power of the internet to start selling their products. With the spurt in online retail sales increasing every year, now surely is the best time to begin your own website for your products. In this article we highlight the necessary points for starting your own website at the earliest. We will cover:-

How you can choose the right software company for web application development.

Steps taken by a software firm to build the website from scratch.

Technical requirements of building a website.

Why a website is a need in these times.

How you can choose the right software company for web application development

Choosing a software development company can be a daunting task, but when you engage in extensive research, then things will be a tad easier. We give you certain parameters which you can use to compare different companies on. But, it is required that the search is done on reputed platforms, that is if you are looking for quality work.

The first thing that needs to be seen is whether the company offers custom software development solutions. The needs of a website are complex as the user traffic gradually increases, hence the need to follow every stage of SDLC is an absolute must. Ensure that the web application development company doesn't use pre-developed themes. 

The end-user of the software plus ensuring that the company can provide the needed user experience is another point to be considered. 

If a company is referred by someone who got their software developed by any firm, it is always better to inquire further about the firm. A strong recommendation is a result of good experience. 

The need for building faster websites is a need now. It is then important to have a major round of discussions with the project development team and a detailed discussion with the team to understand if they can cater your needs.

Security is another concern and it should be taken care that the company you outsource the work to has to respect the confidentiality of the information so provided. 

Be very careful of choosing a firm that has transparent policies. It should be noted that several firms charge hidden costs that come out in the open when it is too late to object.

Steps taken by a software firm to build the website from scratch

It is possible to change the purchase behavior of an individual. People are now increasingly moving towards online shopping, and when you get your build, these steps will be followed. 

Need for a domain name

If there is a website there has to be a domain name. It is important that it should be related to the kind of products you will be selling. It is an important first step as it will help your customers look for you.

Web hosting

You also will need a hosting provider to make your website live and to send data back and forth from a website every time a customer visits your site.

Choosing the CMS platform

Choose the best CMS platform based on three parameters: 

Business requirements- First determine the type of your website. Will it be a simple single brochure one or a multi-connected one with 3’rd party software integration. Based on your business priorities, a good CMS platform can be chosen. For a platform that can provide you wide audiences with multi-lingual support, we support the use of WordPress.

Security- Choosing a CMS also means factoring in the security issues. It is then important to read realistic reviews about the CMS platform. 

Mobile-responsive- WordPress is considered the best when it comes to supporting mobile responsive websites. It also runs some enigmatic responsive themes which can be chosen.

Selecting the right Ecommerce platform

There are many E-commerce platforms to choose from but building a website is not for today but for the future as well. Hence choosing one should be done from that perspective. The platform that one chooses is done so keeping in mind the scalability needs. 

Building site Architecture

Site architecture is extremely important as it denotes the qualities of a well-developed site navigation for your e-commerce business. It is critical that product images are displayed well with proper sub-categories mentioned. A different section also has to be devoted to best-selling and discount products to get customer attention. Some important parts are product details, Reviews and testimonials,Trustmarks, Payment options, website speed and shipping partner selection.

Technical requirements of building a website

The model denotes the logical structure of a database that depicts the relationships and constraints pointing out how data is stored and accessed. For an ecommerce website this is an important aspect as storing product information and accessing product information is critical. When one usually runs a store, keeping the count of the let’s say merchandise is usually done on RDBMS or a sheet. Take the case of shirts that are stored with different aspects like ID, type, color, size and SKU. 

This is how it might look. If more collection has to be added, only the number of rows have to be increased. But if there are also other products to be considered, Let say a jeans also has to be added to the stock and its attributes also will be added. Considering this, several other products like skirts, trousers etc will be added. If the same approach is followed, this is how it will look.

For a small dataset this is fine, but for a large dataset the EAV approach or the entity attribute value can be employed most often used on Woo and Magneto. With EAV, product information is stored in multiple tables. The common factors will be saved in one table and the attributes in another. 

Security

There is nothing as important as the need to protect your site from hackers especially when financial transactions take place. Our recommendation is to have a 256-bit layer transport layer security for end-to-end encryption. HTTPS is recommended which is nothing but HTTP layered with TLS protection. 

High performance

Page load times and irate customers are directly proportional. If the load times increase chances are the customer gets so irritated that they decide against using the site. Page load speed matters as even one second delay can result in a 7% loss in conversion. For high speed these strategies are best to be followed”

Rather than utilizing multiple JS or CSS files or making several requests by the browser, it is better to combine it into one individual file allowing the browser to make one overall single request.

Caching assists the website become fast. It also helps in achieving a better SEO score leading to greater conversion and user satisfaction. 

Content Delivery Networks (CDN) are the right way of delivering content to customers. Its primary role is that it caches the contents on servers which are located in different parts of the world.

Data Compression

Using data compression tools like GZip, data can be compressed before sending it to the browser. It also is good to make modifications in the server configuration files. This will lead to faster load times and superior performance.

Scaling

For a webstore, it is important to scale up when the user traffic increases on the website. In the case of flash sales and discounts, inventory also has to be increased  up to support the increasing load of demand. 

Why a website is needed

Several businesses now flocking to gain IT edge due to COVID-19 might be assuming that all this is temporary. But the reality is that post-covid also the situation shall remain in favor of online retail as this is the new normal. If an organizations does not build one sooner, it will not be able to catch up with the competition.

Get your website built right away!
