Subject RE: Dynamic Forms

I'm interested to know how you are dynamically persisting these fields?
Certainly not in a RDBMS.  Perhaps this can be resolved with better design.

It almost sounds like someone is shoving this design at you and expecting
you to code it this way.  Is this the case?  If not, there are better ways
to structure your application so you don't have to do such a hack job on the
front-end.
