ABSTRACT:
Instead of executing a plurality of submitted transactions separately, each data item to be processed by the plurality of submitted transactions is retrieved only once, update operations of the plurality of transactions are executed consecutively on the retrieved data item in main memory, and only the last updated result is written in a database once.Two-phase locking technique and timestamp technique are used for multi-operation processing providing concurrency control of transactions in order to execute multiple synthetic transactions concurrently.
