I am looking for a good book on semantic data modelling, with practical
applications. I read Teorey's "Data modeling and design" which a good
guide for the use of enhanced ER techniques. I am looking for a book
which describes advanced techniques based on generalization and 
aggregation, something a bit beyond the traditional ER.

Thanks,
Igor V. Gordon
