Answer / Ranbir Kumar

In RDO, there are four types of lock edits: 1) adLockOptimistic, locks the record for editing but allows others to read it. 2) adLockPessimisticWait, locks the record for editing and waits if another user wants to edit the same record. 3) adLockPessimisticForWrite, locks the record for writing and immediately overwrites any changes made by other users since the last save. 4) adLockBatchOptimistic, optimistically allows multiple users to edit the same record until they try to save, then it resolves any conflicts.
