Does Access have pointer(s) to updated records?

Question

I am creating an Access driven program in C#.NET.  I am trying to design it around the concept of multiple users.  One function I'm trying to create is an automatic update for other users should one user add/edit/delete records.  I have already created a file watcher that will watch for updates to a specified file when the database changes.  The only problem is that I don't know WHAT has changed!  Can anybody give me some suggestions on what to do?
