**Intent:** The Business Delegate pattern adds an abstraction layer between
|
||
|
|
presentation and business tiers. By using the pattern we gain loose coupling
|
||
|
|
between the tiers and encapsulate knowledge about how to locate, connect to,
|
||
|
|
and interact with the business objects that make up the application.
|
||
|

|
**Applicability:** Use the Business Delegate pattern when
|
||
|
|
|
||
|
|
* you want loose coupling between presentation and business tiers
|
||
|
|
* you want to orchestrate calls to multiple business services
|
||
|
|
* you want to encapsulate service lookups and service calls
