I am just about complete with setting up my first database and I am trying to figure out the best way to set up my security on it. I was thinking about setting it up using a MDE file, but my only concern is once I set it up as a MDE file, will I be able to go back in and make changes? I know because it is a new database, I will need to add more forms and reports. And if I can not do this, what would be the purpose of ever setting it up as an MDE?
