Concurrency control in business transaction terms usually involves generating and maintaining locks on data stores, such as relational databases.
并发控制在业务事务术语中通常涉及生成和维护数据存储上的锁，例如关系数据库。
Moreover, there are many services that do not have concurrency control at all, which may also lead to inconsistent data.
此外，有许多不具备并发控制的服务，这也可能导致不一致的数据。
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。
This concurrency control can greatly reduce timeout situations between readers and writers accessing the same data row.
这种并发性控制可以极大地减少读取程序和写入程序访问相同的数据行时产生的超时情况。
DB2 extends its common services, such as optimization, indexing, concurrency control, and utilities, across the traditional relational and XML column data.
DB 2对其涉及传统关系数据和xml列数据的常用服务进行了扩展，例如优化、索引、并行控制和实用工具。
DB2 services such as optimization, indexing, concurrency control, and utilities are extended to support XML data along with the relational data.
优化、编制索引、并行控制之类的DB 2服务和实用程序都可以进行扩展，以支持XML数据以及关系数据。
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.
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。
A data management system (DMS) for engineering design can support hierarchical decomposition, multiple levels of abstraction, concurrency control and design evolution.
工程设计数据管理系统(DMS)可以支持设计的层次分解、多级抽象、并发控制和设计进展。
Concurrency control is a technique that data stores use to control how data is read and changed in the store when multiple clients are accessing and manipulating the same data.
并行控制是一项技术，当多个用户端存取和操作相同的资料时，资料存放区使用此技术来控制存放区中资料的读取与变更的方式。
It can also facilitate users to define and manipulate data, maintain the security and integrity of data, and the concurrency control and database recovery under multi-user circumstances.
它使用户能方便地进行定义和操纵数据，维护数据的安全性和完整性，以及多用户下的并发控制和恢复数据库等操作。
Based on the conventional 2pl protocol, we propose our concurrency control theory for data warehouse multiple view to ensure the data consistency of data warehouse.
对传统的2PL协议冲突操作概念加以扩展，本文提出用依赖图方法判断数据仓库实例化视图调度是否可串行化。
Due to this separation, a data warehouse does not require transaction processing, recovery, and concurrency control mechanisms.
由于这种分离，数据仓库不需要事务处理、恢复和并行控制机制。
