Abstract
User Interface (UI) of Enterprise Information Systems deals with various concerns such as the model structure, layouts, widgets, business rules, and localization tangled together. Unfortunately, conventional development approaches fail to efficiently maintain these concerns and forces developers to manually tangle them together. That results in high information restatement, code duplication, and error-prone maintenance. In this paper, we apply Aspect-Driven Design Approach to separate the concerns in UI, and have them automatically tangled together at runtime. Such separation introduces the single point to maintain, and the runtime weaving enables us to deliver context-aware UI. Furthermore, we apply this concept into distributed environment. This allows us to construct UI in various platforms on multiple client devices from the single concerns description streamed from the server.
