The paper describes the design of a framework for enterprise Web applications that adapts their contents to various types of Web-enabled terminals, such as wearable devices, PDAs, and automobile PCs. Such terminals have different capabilities as regards their processing units, user interaction, and communication. Thus, applications must dynamically adapt their contents to each type of device when they provide service sessions. On the other hand, applications that serve various dynamic contents from databases and transactions need to be connected to back-end systems, namely, business objects designed independently of the Web applications. For reuse and easy development of such adaptive and enterprise systems, the framework should separate three concerns: (1) design of business objects, (2) design of logical Web contents, and (3) design of the content adaptation. The paper reports the author's experience in designing, implementing, and applying a framework to a banking system using small display devices, and discusses the design.

This paper presents an experience with a programming language SPOOL which is based on the combination of object-oriented programming and logic programming. This language inherits the capability of knowledge base organization from object-oriented programming and its expressive power from logic programming.
