数据库并发调度与封锁管理

Database Concurrent Dispatch and Blockade Management

“封锁”管理是数据库中用于保证数据库完整性和一致性的措施之一。本文分析了并发操作可能产生的数据错误原因,提出了利用“封锁”机制对数据库加锁的方法。

Using ＂Blockade＂ to control the data stream is one method to secure the integrity and continuity. The article analyses the cases that some data errors may occurred during concurrent operation and quests the reasons and finally proposes a way to use ＂Blockade＂ system to lock the database.
