CRUD Operations

CRUD means Create, Read, Update & Delete. Most applications have some kind of CRUD functionality and we can assume that every programmer had to deal with CRUD at some point. A CRUD application is one that uses forms to get data into and out of a database.

• Here create means insert a data or put a data into the database. We can do it by post or insertOne , the HTTP method.
• Read is for retrieving, searching, or viewing existing entries. We use the get method for this operation.
• Update stands for the update or editing of existing entries. We use update, updateOne, or sometimes the put method to run this operation.
• Delete means delete, deactivate, or remove existing entries. The delete method is used for deleting the data.

These are the four most basic operations that can be performed with most traditional database systems and they are the backbone for interacting with any database.

Hopefully, now it’s clear to all of you.
