However, the traditional real-time database concurrency control protocol does not provide security supports.
然而,传统的实时数据库中的并发控制协议没有提供对安全性的支持。
With optimistic concurrency control, the database manager releases the row or page locks immediately after a read operation.
通过使用乐观并发控制,数据库管理器在完成读操作之后可以立即释放行或页锁。
Optimistic locking is an extremely efficient concurrency control method that guarantees data integrity without placing any physical lock in the database.
乐观锁是一个极其有效的并发性控制方法,它可以确保数据完整性而又无需在数据库中放置任何物理锁。
