JSP with Bean and Data access object (DAO). JSP is the normal jsp page which uses the bean to store employee information. The DAO file also know an Data Access Layer of our application, contains the code perform database operations such as add, change, delete etc.,
This video demonstrates the best usage of MVC architecture in Java.
➡️ The model here is the EmpBean which holds the employee information.
➡️ The index page is the View which is interface used by client to enter the input and get to view the output.
➡️ The controller here the file which accepts the request from client and sets to bean and bean finally manages the database operation.
CRUD – Create, Read, Update & Delete.
With reference to previous video 👉 https://youtu.be/63cIEAnz7Hc which consist of Add operation & Display operation.
In this video the same example has been extended to support Delete operation using display page. The link (url to delete page and ID of record to be deleted) has been generated in the display page for to delete record.
Once user click the Delete link , the control is transfer to delete.jsp page, where the the ID of the record to be deleted is fetch from request object and the same will be deleted from the emp table.
