摘要
载货车辆称重管理系统在大型厂矿企业中占据重要的地位。在该系统中,通常一些用户拥有相同的使用权限,如果这些用户不加以合理控制会破坏数据库一致性,因此怎样避免数据共享中的冲突通常是在系统开发过程中需要解决的关键问题。本文针对称重管理中多用户共享访问实时数据库数据时出现的问题,探讨了并发控制机制和解决并发控制的方法。
The weight management system of Laden vehicle takes an important position in large factories .Usually , some users have the same right of use in the system, if these users are not been controlled reasonablly, the database consistency can been breaken, so how to avoid conflict of Data sharing is usually an important problem,which ?need solved in the system development processing.After studing the theories of database concurrency control ,the paper explores the implementation of concurrency control in weighing in weight management system of Laden vehicle of multi-user database to share real-time data access problems database system .
