Web application development is the process of developing a Web Application. It is more oriented towards communication with the browser than traditional engineering procedures.
Many web application development processes include identifying the problem, sketching the solution, interacting with users, selecting the framework/using the tool, and finally, developing and testing the web application, which is done in most cases in the loop with the users.
A web application, commonly known as a web app, is a software program that utilizes technologies such as HTML, CSS, and JS to create, modify, and manage data (CRUD) stored in a database or files.
CRUD is a term fundamental to developing web applications that are commonly used today. It is an acronym that represents the four basic operations of a resource: creation, reading, updating, and deletion. Web apps are opened through a web browser like Google Chrome and often require a login or signup process.
In other words, a web app is simply a web page that acts like a more extensive program. The user interface is located in the browser, while the actions occur on the server.
