Web Application Development
Web application development is creation of new application program that provide basic functionalities like interacting with the users, connecting to the databases for the specific data, generating results based on requirements of the user. Sometimes these web applications are developed for certain devices or platform. These applications program are located on remote servers and are accessible by the users through their devices over the internet. Examples for web applications are online banking, eCommerce, social networking, blogs, online reservations, etc…
The technologies required to create a web applications are scripting/coding and programming.
These are codes that are written, are processed by the web browser and the web server. The coding are two types, Client side scripting and Server side scripting.
Client side scripting
Server side scripting
These types of codes are executed by the web server. These codes are not visible to general public. When a user makes a request to a web browser, then the request is accepted by the web server and the script is run from a secure web server. The client browser then receives an HTML which is used to provide interactive user interface into the web server databases. The main advantage of using the scripts are for providing the user with a fast response and highly customized report based on the user’s request. The popular server side scripting technologies are PHP, ASP, ASP.NET, Ruby on Rails, Python.
Web Application Frameworks
These frameworks set of program libraries, components and tools that are organized in a systematical manner allowing users to develop and maintain any range of web application projects using a speedy and efficient approach. These are used to promote code reusability for common functions like guidelines, libraries, documentation and structure with certain standards maintained. Reusability increases productivity and decreases time required for development substantially.
Web Application Development Process
Web application development is a practical and procedural approach in application development. The approach involves
Defines the purpose of web application and direction which comes next.
Research and Definition
To research the target audience and to find out the scope of the web application.
Creating a functional summary document and to try to meet specific needs of the target audiences with the help of research work.
Project Management and Team
To know the strength of the team and manage the project by giving specific work to specific people and making sure the web application is delivered in the given time frame.
Technology Selection/Technical specifications
To develop the architecture and structure of the web application. To make sure the proper backups and upgrades are in place to be deployed at any given time.
Making sure that the web application is visually appealing to the users.
Testing it on different web browsers and platforms to check its compatibility and performance. Making sure it meets the user requirements.
After deployment making sure that the web application does not crash and improving the database for further upgrades.
