App Arch Guide 2.0 – Business Layer Guidelines

As a part of Microsoft Patterns & Practices a guide to designing a business layer is available at Codeplex.

According to this guide, the business layer consists of

  • Application Facade, which is optional, and combines multiple business operations into single operation.
  • Business components, representing the business logic, data and workflows.
  • Business entity components, used for passing data between components and representing real-world business entities.
  • Business workflow components.
