    We need assistance on following issue of commit and rollback transaction process A transaction is a set of database operations (such as reads and writes) that are executed in a sequential order and in an all-or-nothing manner. This means that for the results of running these operations to be saved within the database and visible outside the transaction to other database clients, all of the individual operations must succeed. If any of the operations fail to execute correctly, the transaction aborts and every change made from the beginning of the transaction will be undone. The database will then be restored to its previous state as if the operations never happened. Similar to SQL
