Basically, Web Applications are rapid sites joined with server side programming which give functionalities, for example, communicating with clients, interfacing with back-end databases, and creating results to programs.
Cases 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, and so forth..
Technologies:
There are two fundamental classes of coding, scripting and programming for making Web Applications:
I. Client Side Scripting/Coding – Client Side Scripting is the kind of code that is executed or deciphered by programs.
Customer Side Scripting is by and large perceptible by any guest to a site (from the view menu tap on “View Source” to see the source code).
The following are some normal Client Side Scripting advancements:
- HTML (HyperText Markup Language)
- CSS (Cascading Style Sheets)
- JavaScript
- jQuery (JavaScript Framework Library – regularly utilized as a part of Ajax improvement)
- MooTools (JavaScript Framework Library – regularly utilized as a part of Ajax improvement)
- Dojo Toolkit (JavaScript Framework Library – regularly utilized as a part of Ajax improvement)
II. Server Side Scripting/Coding – Server Side Scripting is the sort of code that is executed or translated by the web server.
Server Side Scripting is not perceptible or available by any guest or overall population.
The following are the regular Server Side Scripting advancements:
- PHP (extremely basic Server Side Scripting dialect – Linux/Unix based Open Source – free redistribution, for the most part consolidates with MySQL database)
- Zend Framework (PHP’s Object Oriented Web Application Framework)
- ASP (Microsoft Web Server (IIS) Scripting dialect)
- 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 (broadly useful abnormal state programming dialect and Server Side Scripting Language – free redistribution – lost its notoriety to PHP)
- Python (broadly useful abnormal state programming dialect and Server Side Scripting dialect – free redistribution)
Program Libraries
Program libraries are an accumulation of generally utilized capacities, classes or subroutines which give simplicity of improvement and maintanance by permitting designers to effortlessly add or alter functionalities to a frameworked or measured sort application.
Web Application Frameworks
Web Application Frameworks are sets of program libraries, segments and instruments sorted out in a design framework permitting engineers to assemble and keep up complex web application ventures utilizing a quick and effective approach.
Web Application Frameworks are intended to streamline programming and advance code reuse by putting forward envelope association and structure, documentation, rules and libraries (reusable codes for basic capacities and classes).
Web Application Frameworks – Benefits and Advantages
Program activities and rationale are isolated from the HTML, CSS and plan records. This helps planners (with no programming knowledge) to have the capacity to alter the interface and roll out outline improvements without assistance from a software engineer.
Constructs depend on the module, libraries and apparatuses, permitting developers to effortlessly share libraries and actualize complex functionalities and elements in a quick and effective way.
The structure creates best work on coding with reliable rationale and coding models, and gives different designers the capacity to get comfortable with the code in a brief span.
