If I had to bet on it, I'd suspect that the consultants are going to be using a homegrown set of query-building and/or screen-building tools (which they haven't told you about yet :-). The tools will be issuing queries based on their (already coded-for) "meta-schema" in order to do their work, which of course will be the work of generating code to implement the screens and perhaps reports, perhaps even a generic querying layer between the application proper and the DBMS if the toolset is ambitious.
