CRUD stands for Create, Read, Update, and Delete. It is a set of basic operations that are used to manage data in computer systems. CRUD is commonly used in database applications, but it can also be applied to other types of data storage.
Create
The create operation is used to add new data to a system. For example, in a database application, the create operation might be used to add a new customer record.
Read
The read operation is used to retrieve data from a system. For example, in a web application, the read operation might be used to retrieve a list of products from a database.
Update
The update operation is used to modify existing data in a system. For example, in a messaging application, the update operation might be used to change the status of a message from “unread” to “read”.
Delete
The delete operation is used to remove data from a system. For example, in a social media application, the delete operation might be used to remove a post from a user’s profile.
CRUD operations are often represented as a table:
| Operation | Description |
|---|---|
| Create | Add new data |
| Read | Retrieve data |
| Update | Modify existing data |
| Delete | Remove data |
The CRUD acronym is a simple and easy way to remember the basic operations that are used to manage data. It is a widely used concept in computer programming and software development.
