Locking is the mechanism that the database manager USES to control concurrent access to data in the database by multiple applications.
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。
Efficient management of concurrent access (of service requests to the target) is determined by the performance characteristic of the target database server.
并发访问的有效管理(对目标的服务请求)由目标数据库服务器的性能特性决定。
This provides concurrent access by multiple threads to the human tasks in the database as shown in Figure 2.
这提供了多线程并发访问数据库中的人工任务，如图2所示。
When reorganizing XML indexes, database administrators can use the allow write ACCESS clause in the reorg indexes command to allow concurrent writes on the table.
在重组xml索引时，数据库管理员可以通过在REORGINDEXES命令中使用ALLOWWRITEaccess子句允许并发的写操作。
There can be no concurrent users (the application has exclusive access to the database files), but there are no additional threads nor TCP connection overhead.
不能存在并发用户(应用程序独占地访问数据库文件)，但因此也没有额外的线程和TCP连接开销。
By applying carefully the database functions of transaction handling and concurrent access, the platform guarantees data reliability and data integrity in multi user network environment.
该系统还利用了数据库自身的事务处理与并发控制功能，解决了在多用户网络环境下的数据完整性和可靠性问题。
Transactions ensure database consistency even if there are hardware failures. It also maintains the integrity of data while permitting concurrent multiuser access.
即使出现硬件故障，使用事务仍可保证数据的一致性，在多用户环境下，事务还可维护数据的完整性。
