The user interface (UI) refers to the application screens that users use to view data and submit operations to the Unwired Server.
The user interface includes screens for viewing business data, submitting data changes or transactions, pending activities (operations), operation logs (submitted transactions), synchronization screens (to update data on-demand), and implementation logic to show or hide certain application functionality based on the user or data.
User-interface design includes choosing visualization controls, screen layout and flow design, methods of data validation, event processing and business logic, and interaction with third-party controls and APIs.
