事务

To describe consistent transaction behavior when transactions run at the same time, database researchers have defined a transaction isolation model called serializability .

为了描述同时执行的多个事务如何实现数据一致性，数据库研究人员定义了被称为串行化处理的事务隔离模型。

In order to improve the efficiency of DBMS, Concurrent Control is the basic requirement on concurrent transactions execution. When transactions execute instantaneously, Lock Mechanism which could ensure transaction serializability is a good way. But the problem that LM produces should be faced.

并发控制是数据库管理系统提高运行效率的基本要求，事务并发执行时，采用锁机制是保证事务可串行化的一个方法，但因此而产生的死锁问题是一个必须面对的问题，其根本原因是由于数据共享的要求而造成的。

Serializability may not be implemented using only row-level locks; there must be another mechanism that prevents a newly inserted row from becoming visible to a transaction that has already executed a query that would return the row.

如果仅仅通过"行级锁"是无法实现事务序列化的，必须通过其他机制保证新插入的数据不会被刚执行查询操作的事务访问到。

In addition, a new synchronization scheme, Double-Timestamp Transaction-Level Synchronization model is put forward to solve the synchronization problem under the 3-tier replication architecture (Mobile Client - Synchronization Server - Database Server). DTSTLS utilizes a novel double-timestamp strategy to promote the efficiency of synchronization. Besides, it ensures serializability and consistency of the mobile database system through transaction-level conflict reconciliation.Mobile transaction processing is another key technology to provide efficient information service in mobile computing environment.

通过引入一种乐观并发控制方法与两段锁协议相结合的移动事务处理机制，本文重点解决了交互式长事务的问题，并提供了对移动主机任意移动性和数据库系统一致性的支持；在移动对象数据库方面，本文提出了一种新的移动对象数据库模型—离散时空轨迹移动对象数据库模型，重点阐述了DSTTMOD模型中的位置表示方法及位置更新处理策略，并分别给出了基于GRID文件和基于QUAD树的移动对象索引算法。
