Pessimistic locking presumes that collision or concurrency issues will occur, so a bar is set on the records and later the data is reconditioned. One can execute pessimistic locking by identifying “IsolationLevel" in SQL server collected procedures, AFO.Net level or via utilizing proceeding scope object.

There are four types of locks one can acquire:

  1. Exclusive: when one wants to modify data without wanting anyone else to read the proceedings.
  2. Shared: when one wants to read-only without wanting to update any distinct transactions.
  3. Intent or demand locks: it is utilized to lock hierarchy.
  4. Update lock: when one wants to update procedures or operations which moves via innumerable phases before the real occurrence of updating.
