Web Application Development

Web Application Development


Web Application Development involves the creation of application programs on remote servers that are delivered via the Internet to the user device. There is no necessity to download and access a web application (web app) from a network. A web browser such as Google Chrome, Safari or Mozilla Firefox enables end-users to access a web application JavaScript, Cascading Styling Sheets (CSS) and HTML5 are the most used languages for writing a web application.

Online banking, social networking, online reservations, online forums, eCommerce and shopping cart applications, online training, interactive games are some common examples of the web applications.

There are two sides to web development:

I. Client Side Scripting / Coding


Front-end development is carried out by client-side programming for web applications. A client is a device application, for example, a web browser. Client Side Scripting can be inspected from any visitor of a site.
Here are some Client Side Scripting technologies:

HTML (HyperText Markup Language):- HTML programming will command a browser towards how website content can be displayed on-screen.

CSS (Cascading Style Sheets):- CSS maintains the data that is presented, is in the correct format.

JavaScript:- JavaScript enables the building of user interfaces highly reactive, prevents frustrating page reload and even resolves CSS support problems.

Ajax (Asynchronous JavaScript and XML):- Ajax allows web applications to asynchronously send and retrieve data from a server without interfering in existing page behavior.

jQuery (JavaScript Framework Library – commonly used in Ajax development):- JQuery is a JavaScript library that is fast, small and feature-rich. With an easy-to-use API which runs across multiple browsers, it simplifies things like the HTML documents ‘ traversal and manipulation, event handling, animation, and Ajax.

MooTools (JavaScript Framework Library – commonly used in Ajax development):- With its sleek, well-documented, and consistent APIs, you can write strong and flexible code.

Dojo Toolkit (JavaScript Framework Library – commonly used in Ajax development):- Dojo Toolkit is an open-source modular JavaScript system. It helps the fast improvement of platform-based applications for JavaScript and Ajax Web sites.

II. Server Side Scripting / Coding

The server-side programming enables the programming on the client side and is used for creating scripts for web applications. No visitors or the general public can visit or access Server Side Scripting.
Here are some Server Side Scripting technologies:

PHP:- PHP is a server-side scripting language, that is popular for developing Static websites or Dynamic websites or Web applications.

Zend Framework:- It is famous to develop web applications and services using PHP 5.6+. And also provides 100% object-oriented code using a broad spectrum of language features.

ASP.NET:- ASP.NET allows developers to create web applications, web services, and dynamic content-driven websites.

ColdFusion:- ColdFusion is a rapid scripting environment for creating dynamic internet applications using ColdFusion Markup Language (CFML).

Ruby on Rails:- The Rails framework helps developers to build websites and applications. Because it abstracts and simplifies common repetitive tasks.

Perl:- Pearl used for extracting information from a text file and printing out a report or for converting a text file into another form

Python:- Python is a necessity for both web and desktop applications and is available on Windows too.

Web Application Database

Your Web application needs a location where your data can be stored, for which a database is necessary.
Most common databases are: 
MySQL (relational):- MySQL is an open source relational database management system.
PostgreSQL (relational):- PostgreSQL is an object- related database management system, often simply Postgres, that focuses on extendability and acquiescence with standards.
MongoDB (non-relational, document):- MongoDB is a document-oriented cross-platform database system which is popular as a NoSQL database.

Web Application Frameworks

The Web Application Development Framework, or just a Web Framework, is a software framework that is designed to support web application development including the use of web services, the use of resources and the use of web-based APIs. Frameworks are, in short, libraries that encourage you to develop your app quicker and more intelligently.

Web Application Frameworks – Advantages and Disadvantages


Efficiency:- Works that would usually require hundreds and hundreds of lines of code to compose Now pre-built functions can complete this task in less than a minute. Development is becoming much simpler, so it’s faster and more efficient if it becomes much simpler.

Security:- There are large security applications in this broad framework. The great advantage is the area behind it, where users are enduring testers. You may go to the website of the Framework and let the company know how to fix it if you find a weakness or security trouble.

Expense:- Several significant structures are interconnected and since they also help the programmer to code quicker, the cost to the end customer will surely be lower.

Support:- In general, a framework contains, like any other distributed tools, reports, support groups or large online community forums in order to obtain immediate answers.


You Learn The Framework, Not The Language:- I think this is a major problem. You will definitely find out the framework and not the language itself if you use a framework and have a limited understanding of the language behind it.

Restriction:- There is no change to the core behavior of the framework that indicates that you must comply with its conditions and operate the way it is necessary when managing a framework. Make sure you choose an appropriate framework.

Code Is Public:- The framework is also available to people with bad intentions as it is readily accessible for anyone.

Web Application Testing

In the web application development process, testing is an important part. Examining would sometimes take more time and effort than developing itself.
Here are some required testings for completion of Web application Development process:

Quality Assurance and Bug Testing:- Here it considers the bug fixing and quality of Web Application.
Multiple Browser Compatibility:- Company will test a Web Application for the different browsers so that it would work on all.
Application Security:- Security is more important for a Web Application and therefore will be tested for security purpose.
Performance – Load and Stress Testing:- If a Web App loads in a long time or have a slow processing time then it would not be appreciable. Therefore a performance test is necessary.
Usability:- Usability is also a factor for which a company should test a Web App.
