| 摘 要： | In order to improve the concurrency of multiversion database systems,a conservative MV locking-graph scheduler algorithm is proposed,which takes the power of MVS as a target.The algorithm combines the advantages of locking and graph,and does optimizing processes on read-only and write-only operations to reduce the blocks of transactions.The correctness and complexity of the algorithm are also provided.

| Abstract: | In order to improve the concurrency of multiversion database systems, a conservative MV locking-graph scheduler algorithm
is proposed, which takes the power of MVS as a target. The algorithm combines the advantages of locking and graph, and does
optimizing processes on read-only and write-only operations to reduce the blocks of transctions. The correctness and complexity
of the algorithm are also provided. |
