The complexity is inherent in the problem.  If your database has a 
hundred tables, whether you choose to have mega database instance with a 
thousand functions or a hundred content focused instances with ten 
functions you still have the same complexity.  How you manage the 
complexity and express the interface to the content is the art of design.

If my client module only cares about the data in tables 36 and 42, I 
know which style of interface I prefer to have to understand.
