In the split logic data client-server architecture pattern, the application functionality is split into two parts: one will be implemented on the client side and the other one will be implemented on the server side. This pattern is very complex when compared to the other two patterns because both client and server need separately compiled application programs for their functioning. Before implementing this pattern, it is very important for developers to identify the functions to be implemented on the client and the server side and list out the type of communication dialogs that must happen between the application programs running on the client and the server side.
