Web Application Development

Introduction

Web application development is the creation of application programs that reside on remote servers and are delivered to the user's device over the Internet. It is a client–server software application in which the client (or user interface) runs in a web browser.

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

Technologies

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

I. 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

Below are some 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)
II. 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 are 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 - 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)
