The solution to the roll back problem in Multi - version concurrency control Timestamp protocol

Concurrency control mechanism can largely use the system resources; it develop the advantage of the database resource sharing and is one of the important indicator to measure the performance of the database management system(DBMS). There are many existing types of concurrency control algorithms. This paper introduces the concurrency control of the Multi version Timestamp protocol and optimizes its shortcomings of the rollback problem, giving a new concurrency control of the Multi version Timestamp protocol.
