What is the name for the design pattern that handles database tables through "managers"?

These "managers" are responsible for CRUD operations on 1 database table only. I'll call this pattern the "Table manager" pattern, but I guess that not proper.

So my question is: What is the name for the design pattern that handles CRUD operations for one database table through a "manager"? See picture below.
