SAP MVC Architecture

CRM WebClient UI Architecture: Software Architecture Layers:
The CRM WebClient UI is based on a multilayer architecture on the server side:
􀁸 CRM application and database
􀁸 Business layer
Business object data used during a CRM WebClient UI session, such as business
   partners, products, and transactions, is handled by the business layer.

   Note: The layers are strictly separated.
   􀁸 Presentation layer
   The Business Server Pages (BSPs) are the presentation layer of the CRM WebClient
   UI. They are the basis for the HTML page running in the Web browser.


This separation allows the connection of any business application through Generic Interaction
Layer (GenIL) and Business Object Layer (BOL) to the CRM WebClient UI presentation layer.
The CRM WebClient UI handles not only CRM business objects and processes, but also
ERP system application objects, such as employees from SAP Human Capital Management
(HCM) and ERP sales orders from SAP Supply Chain Management (SAP SCM).
