**Intent:** Object provides an abstract interface to some type of database or
|
|
other persistence mechanism.
|
|
|
|
|
|
|
|
**Applicability:** Use the Data Access Object in any of the following situations
|
|
|
|
* when you want to consolidate how the data layer is accessed
|
|
* when you want to avoid writing multiple data retrieval/persistence layers |
