Web Software Development
WWeb 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.
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..
There are two main categories of coding, scripting and programming for creating Web Applications:
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 are some common Client Side Scripting technologies:
HTML (HyperText Markup Language)
CSS (Cascading Style Sheets)
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)
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).
Today's web applications have substantial business impact on the way companies and consumers do business such as.
There are opportunities to gain the upper hand and bypass the traditional brick and mortar companies when this type of opportunity was rarely possible or existed before the explosion of the web
