What is CRUD?

CRUD is an acronym that stands for Create, Read, Update, and Delete – four fundamental operations for working with data in various database management systems (DBMS). In this chapter, we will delve into the basics of CRUD and its role in data management.

CRUD represents the following four essential operations for data interaction in any database:

• Create: add new records to a database. For example, use it to add new users with data like names and emails;

• Read: retrieve information from the database. Useful for fetching lists of users or products;

• Update: modify existing data. For instance, change a user's address;

• Delete: remove records from the database, like deleting a user's account.

CRUD in Development

CRUD operations are the backbone of any application that manages data. They enable applications to create, read, update, and delete information, which is essential for functionality across various programs: from blogs, where users can add and edit posts, to e-commerce sites, where admins manage products, and task management apps that let users track and update tasks.
