If you are looking for good books on data modeling patterns, I recommend these:
David Hay's Enterprise Model Patterns (and his earlier ones). This is a beast of a book, but has some great patterns.
http://www.amazon.com/dp/1935504053/
Len Silverston's Data Model Resource Book Vols. 1, 2, 3. Good case studies by industry in the last 2 books.
http://www.amazon.com/dp/0471380237/
Michael Blaha's Patterns of Data Modeling . This one has some interesting temporal, graph, and tree models.
http://www.amazon.com/dp/1439819890/
Martin Fowler's Analysis Patterns. This one skims some of the other patterns, but gives accounting a solid treatment.
http://www.amazon.com/dp/0201895420/
They are all well-rated on Amazon and I have read them and they are all very good. A few are available on Safari too.
