    Generally the architecture is defined in terms of Tiers and Layers and more general 3-Tier architecture is as follows:

    1. Presentation Tier
      • This is the top most level of the application. The presentation tier displays information related to such services as browsing merchandise, purchasing, and shopping cart contents. It communicates with other tiers by outputting results to the browser/client tier and all other tiers in the network.
    2. Business Logic Tier/ Application Tier / 
      • The logic tier is pulled out from the presentation tier and, as its own layer, it controls an application’s functionality by performing detailed processing. It interacts as a proxy between presentation and data Access layer. It may contains following furhter components
        • Business Entities
          • Business Entity is an independent role in a Business Process.
        • Business Rules
          • contains the Business logic and / or Business Rules of the application.
    3. Data AccessTier
      • This tier is supposed to act as an adapter between your Object Oriented world (Business Tier) and the SQL world for the Business Layer. This layer may have methods that actually perform CRUD operations and provides OO interface to the Business Layer.
