Back to basics: What’s CRUD?

Standard

Some year’s ago – I got introduced to SQL. At that time, I recall, I was sitting in a lab and one of the first exercises we did was to create a table in a database and adding data in it. In next lab, we ran SQL commands that updated records and deleted few. After we’re done – our instructor told us what we learned were the most basic programming functions i.e CRUD operations

CRUD stands for Create, Read, Update and Delete.

C: Create

R: Read

U: update

D: delete

Let’s see the SQL equivalent of CRUD operations:

OperationSQL
CreateINSERT
ReadSELECT
UpdateUPDATE
DeleteDELETE

Is the concept of CRUD just applicable to SQL?

No. in fact, if you start learning programming or web development – one of the first things that you get to learn is how to run CRUD operations with that particular language.

Conclusion:

In this blog post, I documented four (4) basic programming functions i.e. Create, Read, Update and Delete.
