A reactive architecture for Web-based information systems

Most current Web-based information systems suffer from lack of flexibility. They are hard to be applied to different environments and hard to adapt to frequently changing user requirements. This paper presents a novel approach - reactive system approach to solve these problems. Reactive system concepts are an attractive paradigm for system design, development, and maintenance because it separates polices from mechanisms. With the reactive architecture, users can define different requirements and the Web server can dynamically process them and generate corresponding SQL codes without changing the system. The system is active and independent from specific databases, and thus can adapt to different environments.
