What is Web Application?

Web application or web base application is a computer program or called software program that it runs on web browser or internet browser over the internet. Web applications are used a lot of language to design for use on the internet. It use a combination between server side scripts such as JSP, APS or PHP to handle the storage and retrieval of information from client side and client side script such as HTML and Javascript handle to translate information to end user. Client side refers to web browser that work at client’s computer such as Internet explorer, Google Chrome, Mozilla Firefox, Opera, Safari, or Microsoft Edge. Server side refers to service that work at server side such as IIS (Internet Information Service), Apache, and Apache Tomcat. Database supports with web application such as Microsoft access, Microsoft SQL Server, My SQL, and Oracle etc.

We use web application to client or end user do transaction with other company by using online forms and they can show about service, products, or other information to their client. If we use dynamic webpage of web application, it need web server to manage information that request from clients or end user and sometime, web application need database to store data. If we use static webpage of web application, we don’t need web server to process all information from client or end user. Dynamic webpage is the webpage that it allow owner of webpage can edit information later and static webpage is the web page that it is not allow owner of webpage edit information on page later. Web Applications are working with multiple platforms without think about operating system or other devices and it is easy to maintain.

This is some flow of web application:

• End user input URL or other word on web browser or application’s interface to request to web server over internet.
• Web server got information from client or end user and it forwards this request to server side.
• Server side runs service to process client’s request with database.
• After server side completed process, it will send the result to web server.
• Web server got result from service of server side then it forward the result to client’s browser.
• Client’s browser at client side translates data to show on the browser.
