The acronym stands for Create, Read, Update, and Delete—representing the four main operations performed on data. CRUD is a foundational concept in computer programming, databases, and application design. The process is applicable to relational database management system (RDBMSs) or NoSQL.

What does the CRUD acronym stand for?

1. Create:

The starting point in the data journey. Create means adding new information or records to a system. Think of it as noting down a new phone number in your contacts.

2. Read: 

This is about accessing and viewing data. Whether you’re checking a specific detail, like a friend’s birthday, or browsing through a list of saved songs, that’s the Read operation in action.

3. Update:

Data is rarely static. The Update operation allows for modifications to existing records. For instance, if a colleague switches jobs, you might update their work email in your contacts.

4. Delete: 

This operation removes data. Whether it’s clearing out old emails or removing a discontinued product from an inventory, Delete ensures systems remain current and relevant.

REST vs. CRUD: Key Differences

REST (Representational state transfer) describes HTTP commands for web applications for user-facing data (often files with URL identification). Common REST protocols include JSON, CSV, and XML. CRUD, however, more broadly involves database maintenance and record keeping.


In essence, CRUD operations are integral to the functionality of any software application that interacts with a database or persistent storage. Whether it’s a simple to-do list application, an online shopping platform, or a complex enterprise software, CRUD operations are at the core of data management and manipulation.
