To understand the back end, or the “server side,” you also have to know the front end and how the two interact. The front end, also called “client-side” programming, is what happens in the browser—everything the end users see and interact with. The back end, on the other hand, happens on the server (on site, or in the cloud) and databases. It’s the machinery that works behind the scenes—everything the end user doesn’t see or directly interact with, but that powers what’s happening.

Given the importance of backend frameworks, it is no surprise that developers could choose from a range of frameworks.

A majority of sites are built on PHP, making it one of the most popular back-end scripting languages. But there are plenty of others to choose from - Java, Node.js, Python, Ruby On Rails.

Front-end is a term that involves the building of webpages and user interfaces for web-applications. It implements the structure, design, behavior, and animation of everything you see on the screen when you open up websites, web applications, or mobile apps. The core 3 technologies that all modern front-end web developers work to master are HTML5, CSS3, and JavaScript.

Front-end development entails both web design and front-end web development. However at Devamplify Rev, we focus only on front-end web development, and provide a learning guide on Web design.

Web design governs everything involved with the visual aesthetics and usability of a website—color scheme, layout, information flow, and everything else related to the visual aspects of the UI/UX (user interface and user experience). It is less concerned with the mechanisms beneath the surface that make it all work. Through the use of color, images, typography and layout, they bring a digital experience to life.

Some common skills and tools in web design are:

Adobe Creative Suite (Photoshop, Illustrator) or other design software
Graphic design
Layout/format
Wireframes, mock-ups, and storyboards
Typography

Front-end or client-side web development is the code responsible for determining how the website will actually display the designs mocked up by a designer.

Some common skills and tools traditionally viewed as unique to the front-end developer:

HTML5/CSS3/JavaScript
CSS preprocessors (i.e., LESS or Sass)
Frameworks (i.e., AngularJS, ReactJS)
Libraries (i.e., jQuery)
Git and GitHub.

A database is a collection of data which are interrelated in one or another way. A Database Management System (DBMS) provides a platform where the database can be updated and created by the use of SQL queries. The DBMS also provides relationships between the different tables in a database and also crosses the boundaries across different databases by maintaining relationships between them. DBMS also allows to generate reports, graphs etc which can help the user to perform data analysis.

A relational database is a type of database. It uses a structure that allows us to identify and access data in relation to another piece of data in the database. Often, data in a relational database is organized into tables.

RDBMS stands for Relational Database Management System. RDBMS is the basis for SQL, and for all modern database systems like MS SQL Server, IBM DB2, Oracle, MySQL, and Microsoft Access.

Database Security has many different layers, but the key aspects are: Authentication and Authorization.

Authentication: User authentication is to make sure that the person accessing the database is who he claims to be.

Authorization: Authorization is a privilege provided by the Database Administer. Users of the database can only view the contents they are authorized to view.

Data integrity in the database is the correctness, consistency and completeness of data.
