Repository
|
|
==========
|
|
|
|
Purpose
|
|
-------
|
|
|
|
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
