In-Depth Information
Unless a method for the complete representation of knowledge in a computer sys-
tem is found, the reengineering process will never be finished.
In summary, as XML becomes the data standard on the Internet, XML database
becomes the trend of database technology in e-commerce as well as in production
systems in the future.

Epilogue
Application knowledge is required for information systems reengineering, integra-
tion, and normalization.
