ATM, almost DBA to database interactions are ultimately performed by one giant (~2000 lines) class of static methods. This should be split up into a sub-module where different actions (create/read/update/delete/parameters/etc., maybe even qb & mc) are implemented in different classes. This would not only make the DBa layer more maintainable, but it would also make it easier to implement alternative storage drivers (like, say, Doctrine/PHPCR or something else).
