ZPatterns implements storage logic on the application level. 
Applications have to be aware of (in fact they have to be centered
around) ZPatterns.  This alternate approach keeps storage logic
independent of application logic.  It lets you take any code written for
the ZODB and move it to your RDBMS schema without changing the code
(most of the time :-) ).
