two-phase locking in database systems, a situation where all locks are acquired by a transaction in a growing phase, prior to release of all locks in a shrinking phase. Two-phase locking guarantees serializability, except when worm-holes exist.

Therefore, we designed a mode of concurrency control based on Deterministic Finite Automaton (DFA) and Two-Phase Locking (2PL) protocol7,8 and improved the previous local concurrency control mechanism to enable the whole system to unify the state of RCVS and that of the system or some components. Benefiting from this, problems such as system exception and even system crash caused by concurrent operation can be avoided to a greater extent.
