Software Development


Software Development

Simply put, Web Applications are dynamic websites combined with server-side programming which provide functionalities such as interacting with users, connecting to back-end databases, and generating results to browsers.

Examples of Web Applications are Online Banking, Social Networking, Online Reservations, eCommerce / Shopping Cart Applications, Interactive Games, Online Training, Online Polls, Blogs, Online Forums, Content Management Systems, etc..


Technologies

There are two main categories of coding, scripting and programming for creating Web Applications:

1. Client Side Scripting / Coding: - Client Side Scripting is the type of code that is executed or interpreted by browsers.

Client-Side Scripting is generally viewable by any visitor to a site (from the view menu click on "View Source" to view the source code).

Below we using some Client Side Scripting technologies:


2. Server Side Scripting / Coding: - Server Side Scripting is the type of code that is executed or interpreted by the web server.

Server Side Scripting is not viewable or accessible by any visitor or general public.

Below we using some Server Side Scripting technologies:


Program Libraries

Program libraries are a collection of commonly used functions, classes or subroutines which provide ease of development and maintanance by allowing developers to easily add or edit functionalities to a frameworked or modular type application.

Web Application Frameworks:

Web Application Frameworks are sets of program libraries, components and tools organized in an architecture system allowing developers to build and maintain complex web application projects using a fast and efficient approach.

Web Application Frameworks are designed to streamline programming and promote code reuse by setting forth folder organization and structure, documentation, guidelines and libraries (reusable codes for common functions and classes).

Web Application Frameworks - Benefits and Advantages:

Coding Guidelines, Standards & Convention:

Coding guidelines are sets of rules and standards used in programming a web application project.

These rules and standards apply to coding logic, folder structure and names, file names, file organization, formatting and indentation, statements, classes and functions, and naming conventions. These rules also enforce writing clear comments and provide documentation.

Important benefits of using Coding Guidelines

Web Applications Lifecycle Model:

Web Application Lifecycle is the process of developing a web application and involvement of the multiple teams that are engaged in the development process. Each organization may set forth its own unique style of operating.

Some companies follow a certain standard model such as SDLC (System Development Life Cycle) or Agile Software Development Model.
Web Application Development Process:

Web Application Development Process organizes a practical procedure and approach in application development.

The following list of procedures and suggested documents provide a good outline for a Web Application Lifecycle and Process:


Web Application Testing:

Testing is an important part of the Web Application Development process. On occasion, testing would consume more manpower and time than development itself.

Below are some of the most common testing needed for any web application development process:


Trends and Popularity

The demands for companies to build Web Applications are growing substantially.

If planned and built correctly, web applications can:

Below are good reasons for companies to build web applications:


Business Impact:

Today's web applications have substantial business impact on the way companies and consumers do business such as:
