In this modern world of computer technology all people are using internet. In particular, to take advantage of this scenario the web provides a way for marketers to get to know the people visiting their sites and start communicating with them. One way of doing this is asking web visitors to subscribe to newsletters, to submit an application form when requesting information on products or provide details to customize their browsing experience when next visiting a particular website.
In computing, a web application is a client–server software application in which the client runs in a web browser. HTML5 introduced explicit language support for making applications that are loaded as web pages, but can store data locally and continue to function while offline.
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.
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..
Applications are usually broken into logical chunks called “tiers”, where every tier is assigned a role. Traditional applications consist only of 1 tier, which resides on the client machine, but web applications lend themselves to an n-tiered approach by nature. Though many variations are possible, the most common structure is the three-tiered application. In its most common form, the three tiers are called presentation, application and storage, in this order. A web browser is the first tier (presentation), an engine using some dynamic Web content technology (such as ASP, CGI, ColdFusion, Dart, JSP/Java, Node.js, PHP, Python or Ruby on Rails) is the middle tier (application logic), and a database is the third tier (storage).The web browser sends requests to the middle tier, which services them by making queries and updates against the database and generates a user interface.
- 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 (HyperTextMarkup 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).
