CRUD Operations
Pronunciationkrud op-uh-RAY-shunz
Definition
CRUD stands for Create, Read, Update, and Delete, representing the four basic functions used to manage data in persistent storage. In web development, these operations typically map directly to HTTP methods like POST, GET, PUT or PATCH, and DELETE.
Where you hear it
- In API design meetings when discussing endpoint structures. - While setting up database models and controllers. - In backend documentation describing resource capabilities.
Examples
The user registration form triggers a Create operation to save a new record in the database.
The application performs a Read operation to fetch user profile details for the dashboard.
An admin panel executes a Delete operation to remove inactive accounts from the system.
Common mistake
Assuming that every API endpoint must strictly follow CRUD operations, whereas many complex actions and workflows require custom endpoints that do not fit neatly into Create, Read, Update, or Delete.
