## 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
|
|
