Hello,

I strongly recommend you not to do that because I think this would mean to reimplement whole form module - the bizform.ascx is based on form definition object, there is no direct work with DB. The other reason is that even if you manage to do that somehow you might run into problems during upgrades later.

If you need to query data from all those forms, you should use alternative forms instead (that way you can have 5000 different forms for one table).

If you do not need to perform such queries on all these data, having many forms with many tables is much better idea, because every single one of these tables can be optimized to specific needs of the some group of alternative forms.
