Thank you for your post.
The ideal solution would be to have every iPad access the main database over the network. All changes would be made "real time", so you wouldn't have to worry about two people making changes to the same record.
Assuming that is not an option, syncing via iTunes is fine. You could then run a script that updates the main database file. The disadvantage is that all iPads would need to run the script before copying the data back to the iPads. Otherwise, each iPad would have a different version of the database file.
Let me know if you need additional clarification.
-One central FMP Database on a shared drive
That's not safe. Database should not be in a shared directory (or drive). It should be hosted from this computer with FileMaker Pro or FileMaker Server. If two users attempt to run your "synch" script at the same time over the network, your database could be corrupted.
Thank you both for the reply. Yea, I talked it over with my supervisor and it doesn't seem logical to go about this without getting FileMaker Server, so we are looking into that. It should make things much smoother all the way around
