The JSP CRUD operation App with Codes With Pankaj

7 min readAug 30, 2023

CRUD stands for Create, Read, Update and Delete operations using a database and these are the operations which is the core of many applications.

What are JSP CRUD operations?

Create, Read/Retrieve, Update, and Delete are the four steps in the JSP CRUD process. The four basic roles of persistence storage are as follows.

The JSP CRUD operation can be defined as user interface conventions that allow the view, search, and modify information through computer-based forms and reports. JSP CRUD is a data-driven framework that makes use of HTTP action verbs in a consistent manner. There are a few key verbs in HTTP.

  • POST: This method creates a new resource.
  • GET: Retrieves information from a resource.
  • PUT: Replaces/updates an existing resource with a new one.
  • DELETE: Removes a resource from the system.

MySQL is an open-source relational database management system that can operate on various platforms. It is easy to manage.
