Active-Link Tables Optimistic Record Locking When working with active-link tables, Alpha Five uses a technique called 'optimistic record locking' to prevent one user from inadvertently overwriting changes made by another user. Contrast this with 'pessimistic record locking' - the technique used when two or more users want to edit the same record in a native Alpha Five table. In 'pessimistic record locking' when one user begins to edit a record, the record is locked, preventing the second user from editing.
This video show how optimistic record locking works for an active-link table.
