特定的并发控制机制因商业SDO实现而有所不同，但这超出了本文的讨论范围。
Specific concurrency control mechanisms vary across commercial SDO implementations and are beyond the scope of this article.
文中着重研究移动事务的并发控制机制，提出了一种基于动态计时器机制的并发控制策略。
The paper focused on concurrency control mechanism of mobile transactions and proposed a concurrency control strategy based on dynamic timer.
因为由语言(而不是操作系统)控制并发机制，所以生成数千甚至数百万个进程是很普通的。
Spawning thousands or millions of processes is quite normal, because the languages controls the concurrency mechanism not the operating system.
锁定是数据库管理器用来控制多个应用程序并发访问数据库中数据的机制。
Locking is the mechanism that the database manager USES to control concurrent access to data in the database by multiple applications.
即使JDBCDMS提供了数据更新和用于解决更新冲突的optimistic并发控制(occ)机制，SDO也不可能适合所有的Web应用程序。
Even though the JDBC DMS provides for data updates and an optimistic concurrency control (OCC) mechanism for update collisions, SDO may not be suited for all Web applications.
但是，当同步主要是并发控制的机制时，则事务主要是处理异常的机制。
But while synchronization is primarily a concurrency control mechanism, transactions are primarily an exception-handling mechanism.
传统数据库通过并发控制协议及事务的恢复机制来保证事务的正确性。
In a traditional database system, the transaction correctness is implemented through the concurrency control protocol and the recovery mechanism.
