If you can load the program, you're half way home. If they were doing serious database work, they'd have a serious database to do the work. And I assume that you will not be the Access programmer, but an Access user.

Access is, imho, just like Excel and Word. Some power is there, but most of the usage is with the common, ordinary, features.

And you WILL learn more as you progress. When a stumbling block appears, you only need to post here for an deluge of replies, some might even be helpful. ;-)

Good luck.
