Topic: DB Modeling Book Recommendation
I have been working closely with Rails for almost a year. I can create fairly complex Rails applications but I still consider my understanding on DB modeling could be improved. I can create simple associations but I would like to dig in deeper, I don't want to just know the surface, I want to really know this stuff. For example, Single Table Inheritance and more detailed theory behind Object Oriented Database Modeling.
So I have been searching on Amazon for a good book. Seems there is no Rails-specific book about it. Is there any good Data Modeling book you would recommend for a Rails programmer?
