Application Development in Real-Time?

Hi,

I'm just going through the finishing stages of a year-long project that was supposed to deliver a product to the customer that enables them to build and modify arbitrary database applications in real-time. We pretty much managed to achieve that using a library-assembler design. I think that the last test they made was to build an invoicing program with stock and customer control, and they were able to create the program from scratch in around 3 hours.

Anyway, they've now asked us to provide functional comparisons between what we've provided for them and other 'established' methods for this type of thing.

I've done a couple of net searches and I guess I'm using the wrong search words because I'm not getting anything useful. Do any of you have any pointers?
