About

In computer programming, create, read, update and delete (as an acronym CRUD) are the four basic functions of persistent storage.

Operation	SQL	HTTP	File System	mutator
Create	INSERT	PUT / POST	write	Row Level
Read (Retrieve/Query)	SELECT	GET	read / take	-
Update (Modify)	UPDATE	POST / PUT	write	Field Level
Delete (Destroy)	DELETE	DELETE	delete/dispose	Row Level

CQS Principle - Asking a question should not change the answer. ie Query should not change data.
Design - CQRS (Command Query Responsibility Segregation) - Read not where you write
