What is considered a large database? Right now mine is 3M and we hope to add a lot more features and I'm worried about the size. I know if you convert it to *.mde it will be small and load faster, but b/c you are prevented from doing design changes I'm kind of edgy about that. I would like my users to use the *.mde file to enter their own data, but I what if I occasionally need to make changes, then the *.mdb version of my database will be out of date. Any suggestions, what's the best way to go about this?
