Updating information in the Database will be based on a number of characteristics. Can be based on id, or common characteristics such as the same category, … Update data in Database can update one or more records, depending on the features of the Website.

Example of Update feature in CRUD:

  • Website Administrator corrects the information of a previously created post.
  • Website Users edit comments.
  • Facebook Users edit posts.

4. DELETE – Delete Posts, Delete Comments, Delete Error Orders

Delete an existing record in the Database through the user interface. Deleting an existing user in the Database is the job of the Back-End Developer.

The DELETE feature in CRUD is to remove existing data, data created from CREATE.

In the actual Website Programming project, deleting user data through the interface is hidden. Hide user data so it can be recovered in case of need.

Example of the Delete feature in CRUD:

  • Website Administrator deletes the post.
  • Users delete their own comments.
  • So, what is CRUD? CRUD is 4 main features for working with Database. Almost every feature on the Website is related to CRUD.
