n.可串行性

Lock and serializability are two important methods for concurrency control. 加鎖與可串行化是并發(fā)控制中采取的2個主要措施。

At the same time, this method also can make the mobile transactions:學(xué)報；會報." target="_blank">transaction execute serializability. 同時，通過已有的可串行化理論證明該策略能夠保證移動事務(wù)的可串行執(zhí)行。

In global validation distributed update transactions have to do check to ensure distributed serializability in all participants. 在全局有效性確認中對分布更新事務(wù)進行檢查,以保證分布串行性。

The aim of the distributed concurrency control is to keep the consistency of the distributed transaction and DDB(Distributed Database),to realize the serializability of the distributed transaction and to make transaction have satisfactory concurrency. 分布式并發(fā)控制的目的是保證分布事務(wù)和分布式數(shù)據(jù)庫的一致性，實現(xiàn)分布事務(wù)的可串行性，使事務(wù)具有良好的并發(fā)度以保證系統(tǒng)具有用戶滿意的效率。
