What does R stands for in the CRUD acronym ?

CRUD is an acronym that summarises the four basic operations that can be performed on stored data in a database or system: adding new data, retrieving existing data, changing existing data, and removing data.

The letters map onto these operations as Create, Read, Update, and Delete. The letter R specifically refers to Read, which is the operation of retrieving and viewing data that has already been stored, as distinct from Create, which adds brand-new data, or Update, which modifies data that already exists.

Learn CRUD as a fixed set of four terms, Create, Read, Update, Delete, since exam questions often test recall of the exact word behind each letter rather than a synonym for it.
