Mediates between the domain and data mapping layers using a collection-like interface for accessing domain objects. Repository encapsulates the set of objects persisted in a data store and the operations performed over them, providing a more object-oriented view of the persistence layer. Repository also supports the objective of achieving a clean separation and one-way dependency between the domain and data mapping layers.

Examples

Doctrine 2 ORM: there is Repository that mediates between Entity and DBAL and contains methods to retrieve objects
Laravel Framework
