Can multiple users enter the same database and edit records at the same time?
No. Any number of users can open the same database with Read-Only access. You can place databases in a read-only folder to make sure the databases are always available to multiple users. One user at a time can open a database with Read-Write access. The first user to enter a database with Read-Write access has exclusive rights to edit records, while others receive a “busy” message. The database is not available to others until the user with Read-Write access closes it. A database in use by another user, either Read-Write or Read-Only access, cannot be opened with Read-Write access.
