hi, everybody:
In the FBM assignment, it says " Note that the locking required is effectively a "write" lock only". In my understanding, we do not need to lock the concurrently "read" activities on the record even this record is being modified by another client. Is that correct?
Thanks!

Hi Xiaoma,
That's the way I understand it even though you may get an occasional "dirty read." You just have to remember to run the sequence lock, read, modify, unlock for a booking transaction.
Hope this helps
