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

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

Client Side Scripting / Coding — It is the type of code that is executed or interpreted by browsers. It is generally viewable by any visitor to the site (from the view menu, click on “View Source” to view the source code). Below are some of the common Client Side Scripting technologies:

• HTML (HyperText Markup Language)
• CSS (Cascading Style Sheets)
• JavaScript
• Ajax (Asynchronous JavaScript and XML)
• jQuery (JavaScript Framework Library — commonly used in Ajax development)
• MooTools (JavaScript Framework Library — commonly used in Ajax development)
• Dojo Toolkit (JavaScript Framework Library — commonly used in Ajax development)

Server Side Scripting / Coding — It is the type of code that is executed or interpreted by the web server. It is not viewable or accessible by any visitor or general public. Below are some of the common Server Side Scripting technologies:

• PHP (very common Server Side Scripting language — Linux / Unix based Open Source — free redistribution, usually combines with MySQL database)
• Zend Framework (PHP’s Object Oriented Web Application Framework)
• ASP (Microsoft Web Server (IIS) Scripting language)
• ASP.NET (Microsoft’s Web Application Framework — the successor of ASP)
• ColdFusion (Adobe’s Web Application Framework)
• Ruby on Rails (Ruby programming’s Web Application Framework — free redistribution)
• Perl (general purpose high-level programming language and Server Side Scripting Language — free redistribution — lost its popularity to PHP)
• Python (general purpose high-level programming language and Server Side Scripting language — free redistribution)

Program Libraries: They are a collection of commonly used functions, classes or subroutines which provide ease of development and maintenance by allowing developers to easily add or edit functionalities to a framework or the modular type application.

Web Application Frameworks: They 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. These 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

• Program actions and the logic are separated from the HTML, CSS and design files. This helps designers (without any programming experience) to be able to edit the interface and make the design changes without help from a programmer.
• Builds are based on the module, libraries and the tools, allowing programmers to easily share libraries and implement complex functionalities and features in a fast and efficient manner.
• The structure helps produce best practice coding with the consistent logic and coding standards, and provides other developers the ability to become familiar with the code in a short time.

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

• Roadmap Document: Defining the Web Application, Purpose, Goals and Direction
• Researching and Defining Audience Scope and Security Documents
• Creating Functional Specifications or Feature Summary Document
• Team Collaboration and Project Management Document
• Technology Selection, Technical Specifications, Illustrative Diagram of Web Application Architecture and Structure, Development Methodology, Versions Control, Backups, Upgrades, Expansion and Growth Planning Document, Server Hardware / Software Selection
• Third Party Vendors Analysis and Selection (Merchant Account and Payment Gateway, SSL Certificate, Managed Server / Colocated Server Provider, Fulfillment Centers, Website Visitor Analytics Software, Third Party Checkout Systems, etc.)
• Application Visual Guide, Design Layout, Interface Design and WireFraming
• Database Structure Design and Web Application Development
• Testing: Quality Assurance, Multiple Browser Compatibility, Security, Performance — Load and Stress Testing, Usability
• Maintenance

Web Application Testing: Testing is an important part of the Web Application Development process. On occasion, testing would consume more manpower and the time than the development itself. Below is some of the most common testing needed for any web application development process?

• Quality Assurance and Bug Testing
• Multiple Browser Compatibility
• Application Security
• Performance — Load and Stress Testing
• Usability
