Business Delegate Pattern is used to decouple presentation tier and business tier:
It is basically use to reduce communication or remote lookup functionality to business tier code in presentation tier code.
In business tier we have following entities:
<> Client - Presentation tier code may be JSP, servlet or UI java code.
<> Business Delegate - A single entry point class for client entities to provide access to Business Service methods.
<> LookUp Service - Lookup service object is responsible to get relative business implementation and provide business object access to business delegate object.
<> Business Service - Business Service interface. Concrete classes implement this business service to provide actual business implementation logic.
