ISP Information:
This architecture splits the user interface from the application logic. Servers handle the database management and application logic. This works out to less complexity at the client and a more scalable application. Additional user interfaces can be added easily because the user interface is the only thing that resides on the client. For example, you can easily let customers view data from the Web without changing the app
