In the previous episodes of the series we went through some low level coding test tasks. Today we’ll explore acronyms you need to know. So far we covered SOLID, DRY, KISS, YAGNI, TDD, CI/CD, MVC and REST. Today we’ll wrap up acronyms for a while with last three ones:

CRUD

CRUD is a basic set of operations on data:

• C — Create
• R — Read
• U — Update
• D — Delete

You can create a row in a table, read a row, update the row (whole or specific columns) or delete the row.

In a SQL database these operations are expressed by INSERT, SELECT, UPDATE and DELETE queries. In REST API by HTTP methods called POST, GET, PUT/PATCH and DELETE.
