Editor's note: An experienced provider of Salesforce development services, ScienceSoft dwells on how to start with Salesforce, which technologies to master and how to build a successful career in this domain. In 2019, Salesforce.com, Inc. was recognized as a CRM market leader for the sixth consecutive year. Over 150,000 companies worldwide, including such renowned brands as Sony, Financial Times, Toyota and more, already use Salesforce CRM. As the scale of using the Salesforce CRM is actively growing, Salesforce is expected to generate about 3.3 million employment opportunities including positions for developers by 2022. What is the Salesforce platform Salesforce is a cloud platform for managing sales, customer service, and marketing. The key products for these purposes are Sales Cloud, Service Cloud and Marketing Cloud. The list of the highly demanded products for business also includes Commerce Cloud (for ecommerce), Financial Services Cloud (for financial organizations), and Health Cloud (for healthcare organizations). To enrich their products, SFDC (which stands for Salesforce.com Inc.) offers additional components, for example, CPQ & Billing used for automatic price quote generation and invoicing. In 2007, SFDC launched Force.com, the PaaS product for developers to create and run apps in the Salesforce infrastructure. In 2018, Force.com was renamed into Lightning Platform, but developers still use the original name sometimes. SFDC regularly updates the services and enriches the offering with new products. One of such products is Einstein AI helping businesses to enhance their CRM with predictive analytics for such purposes as identifying the most promising leads (potential clients) for further cooperation. Another ambitious product by SFDC is IoT Cloud. This platform allows collecting, processing and real-time managing data from the devices integrated into an IoT system. For example, in retail, IoT Cloud can aggregate the data from sensors attached to the goods to track their transportation and storage conditions. Job duties of Salesforce developers There are two ways to adapt Salesforce functionality to particular business needs: configuration and customization. Developers are mainly involved in Salesforce customization, but they can also perform configuration. During Salesforce configuration, CRM functionality is tuned via the user interface with no coding involved. This way, one can create tables, objects, fields, build relationships between them, set rules for automating linear work processes. For configuration, businesses usually employ a Salesforce administrator. Salesforce customization is needed when point-and-click tools available in Salesforce are not enough to automate particular business needs. Salesforce customization examples include: Automating complex non-linear business processes. Integrating Salesforce with other systems (ERP, company website, social media, etc.). Creating custom reports and dashboards. Adding Einstein AI capabilities to CRM, etc. Apart from customization and configuration, Salesforce developers build custom applications for Salesforce (IT product companies can add such applications to Salesforce’s marketplace named AppExchange). Basic aspects of Salesforce development Back-end development For server-side development, Salesforce app developers use Apex, a strongly typed object-oriented programming language with syntax similar to Java. Apex code is stored in the format of classes and triggers. Salesforce also has its own data management language SOQL, which is similar to SQL. The Salesforce platform has some peculiarities that developers need to take into account. First, to deploy Apex code, its coverage by unit tests should be 75% at least. Second, the platform has limits for developers (Governor Limits) on performing certain operations. For example, it’s impossible to execute more than 100 synchronous SOQL queries in one transaction. Front-end development User interfaces in Salesforce can be created using the Visualforce or Lightning frameworks. Visualforce is an older framework, comprising a tag-based markup language and a set of controllers. Lightning, on the other hand, is a modern framework that allows creating more interactive user interfaces. The framework consists of Aura Components, a Salesforce proprietary programming model, and Lightning Web Components, a JavaScript-based alternative of Aura. How to become a Salesforce developer Education To obtain the required skills, a Salesforce developer should first of all have education in software development. One can obtain a bachelor’s degree in software engineering, computer science, mathematics or related fields. Then, a Salesforce developer needs to gain Salesforce-specific knowledge, for example, with online courses. There is a variety of online courses and tutorials to learn the basic and advanced aspects of Salesforce development. The majority of them are fee-based. However, Udacity offers a free introductory Salesforce development course, and Udemy often provides discounts. For learning purposes, SFDC offers Trailhead, which is a free platform with courses combining theory and practice of Salesforce development. Learning starts with the Developer Beginner module, which contains basic information about Salesforce development. Apart from the technical skills, the requirements for Salesforce development positions can include Salesforce certification. To obtain a certificate, a candidate takes a fee-based test. There are 5 types of certificates, and the certificate should be periodically confirmed (according to the Salesforce releases) by completing tasks by Trailhead. Salesforce developer vs Java developer Due to the syntax similarities between Java and Apex, Salesforce is often chosen by Java developers. The core benefits they pursue are new job opportunities worldwide (as soon as Salesforce CRM is widely used around the globe), increased salary and just a refreshing change. At the same time, some developers claim that being a Salesforce developer restricts one’s job options while Java development allows choosing versatile projects in the domains that differ from CRM. The career path of a Salesforce developer A Salesforce developer’s career ladder consists of three levels: junior, middle and senior. A senior Salesforce developer can become a Salesforce architect or a Salesforce consultant. A Salesforce architect is the highest point of the Salesforce developer’s technical growth. The architect designs an architectural model of Salesforce CRM and custom applications according to a client’s business needs. This position requires a solid Salesforce development background and a profound knowledge of all Salesforce products and development tools. A Salesforce consultant is an intermediary between a customer and a technical team. The consultant analyses a client’s business needs and offers the most suitable Salesforce means to address them. For that, it’s vital to distinguish the cases when Salesforce customization is really required and when it’s enough to go with configuration. 3 reasons why you may like Salesforce development You don’t like to develop from scratch Lightning Platform has many ready-made components for development, which significantly simplifies a developer’s job. You like to dive into a customer’s business Salesforce development requires exploring a customer’s business processes. Moreover, understanding a customer’s business will be a part of your job duties and will influence your career growth. You like both back-end and front-end development Salesforce app developers work both on the server side and create user interfaces. A Salesforce partner with 11 years of experience, we can provide a custom Salesforce app for your internal use or listing it on AppExchange.

Challenges in Big Data.

SQL Product like SQLite has a small footprint which makes it an inapt technology for Big Data storage. But usage of SQL in an organization like eBay, where data of almost 50 petabytes is processed, indicates that some SQL products can be used for running Big Data systems. The lack of schema-less properties in NoSQL repositories and similar systems makes it abstruse how the data is stored and is interrelated. In the case of SUPERSEDE software, it gets strenuous as it tries to peruse integrated analysis over multiple, evolving, and heterogeneous data sources. Another big challenge of big data is privacy. Privacy protection is not easy in the age of big data, and it is a subjective concept as well. It is very strenuous to reach a clear or global definition of privacy. The fast development of data mining and machine learning techniques is putting an enormous threat to privacy. A good and reliable privacy protection method can be breached without many efforts in the future with the advancement of technologies. A large scale of data with limited computing power is generated by mobile devices. It is a disadvantage for encryption and decryption algorithms. And not much advancement was done in privacy policy after 2007. A gradual change of (Human Resources) HR mindset towards Big Data is seen in recent times. Data is too big to ignore, and the Human Resource Managers are deciding with the help of data. As per Nick Holley’s research paper Big Data and HR, there are two threats that Big data usage brings. It is HR Luddites and data centricity. Other known challenges in Big Data is lack of storage understanding (no backup or proper storage facility), confusion with big data tool selection, lack of data professionals (data handling tools are evolving but there are not sufficient professionals in the field), the complexity of managing data quality, and troubles of upscaling. The high dimensionality of big data brings noise accumulation, spurious correlations, and incidental homogeneity. These high dimensionalities with a large sample size create issues like high computational cost and algorithmic instability. Finally, big data brings technical, managerial, and economic challenges in (Small and Medium Enterprises) SMEs.

The biggest challenges in big data during recent years

Big data can simply be defined in terms of four V’s: Volume, Velocity, Variety and Veracity. These four V’s cause many of the challenges that organizations encounter in their big data initiatives. I have listed some of the most common big data challenges faced today:

1. Lack of understanding and acceptance of big data

Oftentimes companies fail to understand the basics of what big data actually is, the benefits it brings, the infrastructure required etc. Without a clear understanding, big data adoption projects can be doomed. Companies can waste a lot of time and resources on things they don’t even know how to use. Some companies can be even more reluctant to make a change and adopt big data in their business. All this can severely impede growth and progress of the company.

2. Massive amounts of data and growth challenges

While talking about big data, the most obvious challenge we can think of is, simply storing all that data. IDC estimates that the amount of information stored in the worlds IT systems is doubling every 2 years. At this pace we can only imagine the amount of data businesses would have to deal with 5 to 10 years from now. Much of this data is unstructured and comes from documents, videos, audio etc. meaning that you cannot find them in a database. Even though the cost of storage is getting cheaper and faster, it cannot keep up with the rate at which data is generated every day.

3. Complexity of managing data quality

Since data can come from a variety of different sources and formats, businesses can run into data integration issues sooner or later. For example, an ecommerce company would have to analyze data from website logs, call centers, social media handles etc. Also, the format of data can differ from source to source. This can be a challenge if no process is in place to integrate and analyze all this data.

Data reliability can also be an issue here. Not all data collected is accurate. Not only can it contain wrong information, but also duplicate itself, as well as contain contradictions. Understanding this and making the most out of the collected data can be a challenge.

4. Security of data

Companies are so busy collecting, storing and analyzing data that they usually neglect and push data security for later stages. This can be a huge issue. We usually read about security breaches a lot in the news nowadays. Unprotected data can be a breeding ground for malicious hackers. This can cause companies to lose millions of dollars. This shows that data security is not taken seriously by many companies and by the time the damage is done, it would have been too late.

EFFECTIVE SOFTWARE DEVELOPMENT-USING RFP

An RFP stands for “request for proposal” and is generated as a part of the bidding method for a product or service. The cause of an RFP is to offer an established manner for organizations to find out about doing business with software program development teams. The RFP specifies what the client is searching out and describes every assessment criterion on which a dealer's proposal may be assessed.

Why should we write RFP?A well-organized RFP is

essential

while encountering a decision-making process.It makes it less complicated for you and your capability dealer to create long-time period enterprise relationship and meet every other’s expectations.The more powerful the RFP is in imparting the essential information, the more effective the final choice may be while meeting the desires of the enterprise. That is why, a best RFP can dictate the fulfillment or failure of your challenge.

Source:

https://www.scnsoft.com/blog/software-development-rfp

1.Write about your company

As you write the challenge summary, point out its goals, objectives, necessities, regulations in a easy and complete manner. Include data about your target audience. Make it informative and compressed. Most possibly you're to edit this component more than one instances later, however make certain you begin with it now. Add some paragraphs approximately your organisation and its background.

2.Project parameters

When it involves project management, those 4 elements – time, cost, quality and quantity – represent the maximum essential parameters. It is important, right from the beginning of your challenge planning, to try and outline the manner wherein every of those will have an effect on your challenge. Double check your parameters with every challenge stakeholder to make certain you don’t miss crucial data.

3.Consult your Stakeholders

Request the input of anybody who has a stake in product delivery, which might also additionally encompass the head of enterprise improvement, marketing, or sales. Their point of view and understanding is crucial earlier than the maximum important information are introduced to the RFP. On the opposite side, vet professional applicants with the aid of using requesting references and performing site visits. Spending time on those activities will offer you with an intimate look into a organisation’s skills.

4. Use the right methods

The RFP (and RFQ) need to encompass a requirement spreadsheet. This table allows applicants test-off whether or not they could meet your desires. Use a reverse engineering method to create the RFP template. If you believe you studied you can have gaps, studies associated providers to peer what kind of skills they offer. Deconstruct your concept of a finished, a success product, running backward to show every skill, process, and feature essential to finish the task successfully. When you create your necessities spreadsheet, remember including a column to signify the priority stage of a demand. This lets in you to sort the listing with the aid of using precedence stage. It may also display you which of them ones carriers supply the best range of must-have gadgets at a look while comparing proposals.

5.Separate Top Requirements From Wish-List ItemsBe certain to differentiate top necessities, or “must-haves,” from “wish-list” items, or gadgets that could be fine to have. Not doing this will waste time as the seller scrambles to determine out a manner to satisfy all of your desires—even the much less essential ones.

POINTS TO INCLUDE IN YOUR RFP:1. A organisation’s background: a quick records at the back of your organisation, data approximately your merchandise or offerings, values and uniqueness in opposition to the competitors.

2.

Apache Cassandra vs HBase: что и когда выбирать для NoSQL в Big Data

Рассмотрев ключевые сходства и различия Cassandra и HBase, сегодня мы поговорим, в каких случаях стоит выбирать ту или иную нереляционную СУБД для обработки больших данных (Big Data) в NoSQL-хранилище.

Где используются NoSQL-СУБД в Big Data

Прежде всего отметим основные области применения рассматриваемых нереляционных СУБД. Проанализировав наиболее известные примеры использования (use cases) Apache HBase и Кассандры, можно сделать вывод, что обе системы широко применяются для обработки временных рядов в следующих направлениях Big Data: · показания smart-датчиков в IoT/IIoT; · сбор и аналитика событий пользовательского поведения (действия, счетчики веб-сайтов и т.д.), в том числе для построения рекомендательных систем, о чем мы рассказывали здесь на примере стримингового сервиса Spotify; · финансовые системы (биржевая аналитика, обнаружение мошенничества); · агрегация данных из систем обмена сообщениями (чаты, мессенджеры, электронная почта, смс и пр.) Все вышеотмеченные приложения обусловлены главными достоинствами Apache HBase и Cassandra: отказоустойчивостью, масштабируемостью, гибкой моделью данных и высокой скоростью обработки информации [1]. Однако, несмотря на общие свойства и области прикладного использования, иногда необходимо выбирать между этими двумя системами. Для этого важно учитывать контекст их применения и специфические характеристики каждой СУБД, о чем мы поговорим далее.

Ключевые аргументы в пользу Apache HBase

Напомним, HBase работает поверх Apache Hadoop, храня данные в HDFS и используя службу Zookeeper для координации работ между сервисами, управления их конфигурациями и синхронизацией. Поэтому при наличии уже существующей хадуп-инфраструктуры целесообразно сделать выбор в пользу Apache HBase. Однако, с учетом специфики распределения данных по узлам кластера согласно механизму регионирования, для работы HBase необходимо достаточное количество региональных серверов. Благодаря своим архитектурным особенностям (блочный кэш HDFS, Bloom-фильтры и собственная система индексов), эта NoSQL-СУБД считается более подходящей для произвольного доступа к данным в виде множества согласованных операций чтения. Кроме того, она позволяет работать с большими данными как в поточном, так и в пакетном режиме, в. т.ч. используя преимущества вычислительной модели MapReduce [2]. Наконец, стоит помнить о наличии целого ряда инструментов, позволяющих выполнять SQL-запросы к данным, хранящимися в нереляционной СУБД: Apache Phoenix, Drill, Hive и Cloudera Impala. Также HBase предоставляет разработчику Big Data собственные REST-интерфейсы и другие API, которые на практике бывают удобнее аналогичных решений Кассандры (SQL-подобного языка CQL, Java- и Thrift-API) [3]. Таким образом, с учетом некоторых ограничений, HBase может быть основой OLAP- и даже OLTP-решений, когда ACID-транзакции не являются строго обязательными. Например, если необходимо просканировать огромные объемы информации, чтобы найти какие-то конкретные данные в небольших количествах. Из-за отсутствия дублирования данных, HBase будет отличным выбором. Также эта СУБД подойдет для работы с данными по моделям машинного обучения (Machine Learning), организации корпоративных хранилищ и озер данных (Data Warehouse, Data Lake) с целью BI-аналитики [1]. В частности, именно так Apache HBase используется в российском отделении Раффайзен-банка [4]. Пример архитектуры Data Lake в российском отделении Раффайзен-банка

Когда использовать Cassandra и почему

Кассандру стоит предпочесть в следующих случаях: · необходима самостоятельная система, независящая от сторонней инфраструктуры; · требуется ACID-поддержка транзакций (хотя легковесная, бы на уровне одной записи) и вторичная индексация (без привлечения дополнительных инструментов, как Apache Phoenix в случае HBase) [5]; · проектируемая система больше ориентирована на запис��, чем на чтение данных – Cassandra записывает информацию быстрее, чем читает, о чем мы подробно писали здесь. Таким образом, Cassandra отлично подходит для веб- или мобильных приложений, а также проектов со сложной аналитикой и анализом в реальном времени для географически распределенных Big Data систем. Например, приложение транспортного мониторинга, которое в режиме онлайн собирает и обрабатывает информацию с IoT-устройств, расположенных на наземном транспорте (автомобили, автобусы, грузовые машины и т.д.) [6]. Пример IIoT-системы транспортного мониторинга на базе Cassandra Как настроить и эффективно эксплуатировать нереляционные СУБД для интерактивной аналитики больших данных, вы узнаете на наших практических курсах в лицензированном учебном центре обучения и повышения квалификации ИТ-специалистов (менеджеров, архитекторов, инженеров, администраторов, Data Scientist’ов и аналитиков Big Data) в Москве: HBASE: Администрирование кластера HBase Смотреть расписание занятий

Apache Cassandra и HBase: конкуренты или альтернативы – 10 ключевых сходств и отличий

Cassandra и HBase считаются наиболее популярными NoSQL-СУБД в мире Big Data. Сегодня мы поговорим, что между ними общего и чем отличаются эти нереляционные базы данных, сравнив их по 10 ключевым параметрам: от архитектуры до инструментальных средств.

Что общего между Apache Cassandra и HBase: 5 главных сходств

Прежде всего отметим, чем похожи HBase и Кассандра. Проанализировав главные достоинства и недостатки этих нереляционных СУБД, мы выделили следующие их общие качества: · История разработки – обе рассматриваемые СУБД написаны на языке программирования Java примерно в одно время: Cassandra создана в 2008 в Facebook, а HBase – в 2007 в Powerset. Проектами верхнего уровня Apache Software Foundation эти продукты стали в 2009 и 2010 гг. соответственно. · Модель данных – обе системы основаны на концепциях Google Big Table и являются колоночно-ориентированными хранилищами, где информация хранится хранятся в ячейках, сгруппированных в столбцы, а не в строки данных [1]. При этом сами столбцы (колонки) группируются в семейства (Column Family), а в общем хранилища относятся к типу «ключ-значение» (key-value). Несмотря на общие термины, их реализация в рассматриваемых системах немного отличается: столбец Кассандры больше похож на ячейку в HBase, а семейство столбцов – на таблицу соответственно. Также в модели данных Cassandra реализуется понятие «пространство ключей» (keyspace), чего нет в HBase. В свою очередь, в HBase есть концепция региона - диапазона записей, соответствующих определенному диапазону подряд идущих первичных ключей, что позволяет балансировать размером таблицы и распределением по узлам кластера. Однако, обе модели являются гибкими, поддерживают маркирование данных метками времени (timestamp) и отлично подходят для хранения больших объемов разреженных данных, допуская отсутствующие значения в определенной ячейке или столбце и не занимая при этом места для хранения. В обоих случаях необходимо указывать семейства столбцов при разработке схемы данных, которая потом не изменяется, тогда как в определении столбцов допустима гибкость в любое время [2]. · ��ысокая скорость работы – при том, что обе СУБД работают быстро, практически в режиме реального времени, в плане производительности операций чтения и записи они отличаются. В частности, благодаря своим архитектурным особенностям, о которых мы рассказывали здесь, Кассандра работает быстрее своего конкурента [3]. Однако, в случае произвольного доступа к данным в виде множества согласованных операций чтения HBase может работать эффективнее Cassandra благодаря блочному кэшу HDFS, Bloom-фильтрам и собственной системе индексов [2]. · Информационная безопасность – обе базы данных поддерживают аутентификацию, авторизацию и шифрование между узлами, обеспечивая не только общее управление доступом, но и детализацию на уровне отдельных элементов модели данных. В частности, Cassandra обеспечивает доступ на уровне строк, а HBase – даже на уровне отдельных ячеек. При этом Кассандра позволяет определять роли пользователей, устанавливая для них условия видимости данных. В HBase, наоборот, администратор назначают метку видимости для наборов данных, в последствие распространяя их на группы пользователей и отдельных клиентов [2]. · Масштабируемость и отказоустойчивость – HBase и Cassandra линейно масштабируются, позволяя добавлять новые серверы и наращивать таким образом кластеры до сотни узлов. При этом обе системы гарантируют сохранность информации, даже при сбое отдельных узлов за счет репликации данных [4]. Сравнение моделей данных Apache Cassandra и HBase

Чем Apache HBase отличается от Кассандры: 5 ключевых различий

При всех вышеотмеченных сходствах, HBase и Cassandra существенно отличаются друг от друга по следующим характеристикам: · Архитектура – кластер HBase работает по принципу ведущий/ведомый (master/slave), когда главный сервер (Master Node) управляет остальными узлами. Поэтому отказ главного сервера влечет за собой сбой всего кластера. Этого недостатка лишена Apache Cassandra, организованная в виде кольца равнозначных узлов, по которым распределены данные. Побочным эффектом такой отказоустойчивости Кассандры является проблема согласованности данных, когда одна и та же информация на разных узлах может отличаться. Для борьбы с этим в Cassandra предусмотрены настраиваемые уровни согласованности (consistency levels), о которых мы подробно рассказывали здесь. В HBase целостность данных обеспечивает центральный сервер (Master Node), который, как мы уже отметили, отвечает за распределение данных по остальным узлам, и сам является потенциальной точкой глобального сбоя. · Инфраструктура – Кассандра самодостаточна, т.е. она не нуждается в дополнительных файловых хранилищах и других внешних компонентах, обеспечивая как управление, так и хранение данных. Взаимодействие между узлами кластера происходит по одноранговому Gossip-протоколу [5]. А для работы HBase необходимы компоненты Apache Hadoop: распределенная файловая система HDFS для хранения данных и служба Zookeeper для координации работ между сервисами, управления их конфигурациями и синхронизацией. · Средства работы с данными – HBase предоставляет разработчику Big Data более широкий набор возможностей: REST и другие API-интерфейсы Java, а также внешние SQL-решений (Apache Phoenix, Drill, Hive и Cloudera Impala), позволяющие работать с данными, хранящимися в HBase, как с реляционными таблицами. Сама СУБД поддерживает только 4 основные действия по обработки данных, которые отличаются от классических SQL-запросов (put, get, scan, delete). В свою очередь, Cassandra имеет собственный SQL-подобный язык запросов (CQL, Cassandra Query Language), позволяющий выполнять простейшие выборки (SELECT) по определённому условию. Оператор UPDATE обеспечивает добавление и обновление информации, а INSERT отсутствует. Также CQL поддерживает пространство имён и семейств столбцов. Драйверы с поддержкой CQL реализованы для языков Python, Java, Ruby, PHP, JavaScript и Perl [6]. · Поддержка индексации – Cassandra поддерживает вторичные индексы, создать которые можно с помощью CQL-выражения CREATE INDEX [6]. В HBase индексация возможна только по одному полю – первичному ключу (Row Key). Добавить вторичный индекс можно с помощью Apache Phoenix, который компилирует SQL-запросы в собственные API-интерфейсы NoSQL без использования MapReduce [7]. · ACID-транзакции – из-за ограничений, выраженных в CAP-теореме [8], принято считать, что распределенные NoSQL-СУБД, в отличие от реляционных баз данных, не могут обеспечить все ACID-требования к транзакциям (атомарность, согласованность, изолированность, долговечность) [9]. В частности, Apache HBase прямо сообщает об этом [10]. Однако, Cassandra обеспечивает ACID-транзакции на уровне одной записи, т.е. для набора столбцов с одним ключом [11]. Архитектура кластеров Apache Cassandra и HBase Таким образом, Apache Cassandra и HBase сложно назвать прямыми конкурентами или равнозначными альтернативами, поскольку они слишком отличаются по множеству параметров даже в общих свойствах. В следующей статье мы рассмотрим, в каких случаях следует выбирать HBase, а когда при построении Big Data системы с использованием NoSQL-СУБД стоит использовать Кассандру и почему. Все тонкости установки, настройки, администрирования и эксплуатации нереляционных баз данных разбираются на наших практических курсах в лицензированном учебном центре обучения и повышения квалификации ИТ-специалистов (менеджеров, архитекторов, инженеров, администраторов, Data Scientist’ов и аналитиков Big Data) в Москве: HBASE: Администрирование кластера HBase
