中文摘要 | 本文討論資料庫系統中各種並行控制的方法(concurrency control mechanisms),例如鎖定(locking),時戳(time stamp)以及迴轉(roll back)等等,並討論如何評估這些方法的效能(performance)。 在分散式環境中維持安全策略(security policy)的一致,是現今分散式資料庫應用中重要的議題,本文描述一個維護安全策略一致性的模組(model),並且說明如何應用並行控制技術來完成實作。 |
英文摘要 | In this paper, ideas that are used in the development of concurrency control mechanisms have been studied. There are locking, time-stamp, and roll back mechanisms included. Measures of evaluating the performance are briefly presented. It is important to maintain consistency of the security policy in distributed environment. We present a concurrency control model in the distributed database system by employing the locking mechanism. |
