The acronym CRUD refers to all of the major functions that are implemented in relational database applications. Each letter in the acronym can map to a standard SQLstatement, HTTP method or DDS operation:

Operation SQL HTTP DDS
Create INSERT PUT / POST write
Read (Retrieve) SELECT GET read / take
Update (Modify) UPDATE PUT / PATCH write
Delete (Destroy) DELETE DELETE dispose

В общем да, вообще любая работа с данными - CRUD.
