Design and implementation of database powered web systems-experiences from the DEMETER project

摘要

A novel design and implementation technique for Web-based distributed information systems is introduced. using a state machine model, a database powered Web application prototype has been successfully implemented. It is a Europe-wide product marketing system for rural areas funded by the European Commission, and is currently in the pilot phase. These experiences have led us to the development of framework tools to close the semantic gap between distributed databases and the Web browser as standard user interface.
