What do I still understand:
Business Representative - In the presentation level, in the form of ASP components Provides an interface for the episode of the APP so that they can access business components without exposing their API, thus pairing can be reduced between the two. Session mask - In the business level, in the form of COM + component, captures business objects, the course provides grains. Interface coupling reduces coupling to reach the business component, concepts complicate business component hides.
So what is the real difference? They look like me ..
session mask lives on < Strong> business level . A mask occupies complex interactions between business objects participating in a workflow, provides a coarse grain service interface to customers and takes care of the limits of transactions .
Professional Representative Presentation Level . Use it to reduce the coupling between the presentation-level and the business level and hide customers << strong> away from complexity related to network calls (finding remote components and calling, handling exceptions, Etc.)
Then business representative and session mask are related and used together (usually between a representative and a mask one by one) -a mapping) but they are different And different motivations.
