Update

Definitions

1. The 'U' in CRUD — a write operation that modifies one or more fields of an existing record or resource in place, as opposed to creating a new record or deleting an existing one. Corresponds to SQL UPDATE, HTTP PUT/PATCH, and similar mutating operations.

   In plain English: Changing some information in an existing record without deleting it and starting over.

   Example: "The PATCH endpoint updates only the fields you send, so you can change just the user's email without touching anything else."
