Updating a database simultaneously
My current database is password encrypted. I am allowing two other users on two different computers the ability to modify the database. The database isn't synced such that if Person A modifies the database at 10 AM, it will automatically show up on Person B's computer at 11AM so that Person B can continue to modify the database. Furthermore, if two people are simultaneously working on the database, then the modifications that Person A does will not show up on Person B's version of the database. Is there any way to get around this, or can only one person modify the database at a time.
