Web Application

Web application Definition

Any application which runs via internet/intranet and there is data exchange between remote application and  your local machine is called as web application. You can also call it as a software that uses HTTP as its primary communications protocol, and delivers web based information in HTML. Web applications can be either browser based or client based
Browser Based: All the instructions and data is contained in the web page retrieved from a Web site. Web page generally consists of javascript , css, html and flash files which gets executed by the browser
The data for the application may be stored on the Web, locally or in both locations.
Client Based : A client component is downloaded in each session or it remains in user’s local machine and can be used for communicating. So here the web application is running without browser.This is similar to the “client/server” architecture that prevailed in companies before the Internet exploded, except that the server is on the Internet, not the local network.
The main aim  of all web applications is to facilitate the completion of one or more tasks. Unlike visitors to traditional static or content rich websites, users of web applications invariably arrive with specific goals, tasks, and expectations in mind.These applications are more interactive with users.Also, web applications have to support an end-state in a way that content-based sites typically don’t.
Some examples of web applications where you see interaction may be any job portal, banking website ,web mail etc.

Web Application Process

Designing and developing a web application is not that easy and you need to make sure that you follow processes while developing a web application.
If you don’t use a methodic approach, especially in case of a complex project, you run the risk of losing sight of the project, not respecting times of delivery and waste your time for nothing.
There are many processes for making web applications which got evolved gradually as per needs and specific circumstances.
In general, you can identify following 5 main phases for developing a  web application
1. Requirements :
Define the scope and needs of your web application in terms of what your application must do.Point out main features and technical requirements. Make sure that you have clear objective before developing or thinking of a web application.
Also have an estimates about potential traffic and users and choose a good serverside language like Java,Asp or PHP.
2. Design :
This will invlove creating some maps/charts or diagrams where you represent pages or actions with some blocks and show relationship among them. Also, this is perfect time to design application database. Write down all pages of the application and the flow.Also design or note down  some common frameworks or libraries that can you used.
3. Implementation :
Now you have requirements, design, database and you know the serverside language, so you can start implementing the logic.
Try to follow all industry standards and coding ways while writing your code. Follow some good design patterns as applicable.
4. Test :
This is a crucial phase of application development. Many people ignore or give less priority but this tells about the quality of product. Test all functionalities in all browsers and then different environments.
5. Release :
Finally you are ready to release your application! While publishing , make sure that you have a deployment plan. Be prepared for all scenarios in deployment, like reverting back to old application. Always give versions to your releases  and take regular backups. Check our Web Application Development services also.

Questions received last week:

What are web 3.0 applications? Shall I even consider them while making my new app for business?  -Andy

web 3.0 applications  is about openness.You  “open” application programming interfaces (APIs), protocols, data formats, open-source software platforms and open data for other to use.
web 1.0 applications were read only, like static websites and then came web 2.0 applications which are read and write only, means you added interaction with you application,  see blogs, social networks and communities are best example of Web 2.0.
web 3.0 applications provides  read , write and execute and it added more intelligence to your api’s . Some of the Web 3.0 technologies are Web 3.0 technologies Artificial intelligence, Automated reasoning, Cognitive architecture, Distributed computing, Scalable vector graphics ,  Knowledge representation etc. Experts believe that the Web 3.0 technology will cause or make search engines, which are much more smarter than the recent search engines.
Well to about your question regarding considering it for your new application, I will say yes,but again look at the use , traffic and users. If your service deals with huge data and data   from various places/applications, then it is better to go for Web 3.0 and give your users a great experience.

Thanks
