The presentation logic component is responsible for formatting and presenting data on the user's screen The processing logic component handles data processing logic, business rules logic, and data management logic.  Finally, the storage logic component is responsible for the storage and retrieval from actual devices such as a hard drive or RAM.Database architectures can be distinguished by examining the way application logic is distributed throughout the system.  Application logic consists of three components:  Presentation Logic, Processing Logic, and Storage Logic.

By determining which tier(s) these components are processed on we can get a good idea of what type of architecture and subtype we are dealing with.
