CRUD

Create, Read, Update, and Delete

The four basic operations that can be performed on persistent data in a database or other storage system.

• Create: This operation adds new data to the system. In a database, it usually involves inserting a new row into a table.
• Read: This operation retrieves existing data from the system. In a database, it usually involves querying the database to select specific rows or columns from a table.
• Update: This operation modifies existing data in the system. In a database, it usually involves changing the values of one or more columns in a row.
• Delete: This operation removes existing data from the system. In a database, it usually involves deleting a row from a table.

CRUD operations are fundamental to most applications that interact with data. They provide a way to manage and manipulate the application’s data to function.

In the context of RESTful APIs, CRUD operations are often mapped to HTTP methods:

• Create: POST
• Read: GET
• Update: PUT or PATCH
• Delete: DELETE

This allows applications to interact with data using standard HTTP requests, making integrating different systems and services easier.
