Above is the screen capture for duwamish layer template.
The Duwamish 7.0 architecture is divided into four logical layers:
Web Layer
The Web layer provides access for clients to the application. This layer is implemented as the Web project in the Duwamish.sln solution file. The Web layer consists of ASP.NET Web Forms and code-behind files. The Web Forms simply provide the user experience in HTML, while the code-behind files implement event handling for the various controls.
Business Facade Layer
The Business Facade layer provides interfaces to the Web layer to handle accounts, category browsing, and book purchasing. This layer is implemented as the BusinessFacade project in the Duwamish.sln solution file. The Business Facade layer serves as an isolation layer, segregating the user interface from the implementation of the various business functions. Apart from low-level system and support functions, all calls to database servers are made through this assembly.
Business Rules Layer
The Business Rules layer, which is implemented as the BusinessRules project in the Duwamish.sln solution file, contains the implementation of the various business rules and logic. Business rules do tasks such as the validation of customer accounts and book orders.
Data Access Layer
The Data Access layer provides data services to the Business Rules layer. This layer is implemented as the DataAccess project in the Duwamish.sln solution file.
