针对传统的关系型数据库管理系统无法满足具有事务限时响应的实时性应用的问题 ,以及为了提供移动通信网本地位置寄存器HLR中的高可靠和高可用的访问服务 ,提出了一种实时数据库与商用数据库相结合的实现模式 ,用以提供大容量大事务处理能力和电信级高实时性响应的服务 ;分析了系统基于事务响应时间限制优先级要求的并发控制原理及利用主动触发机制解决数据竞争的实现方式 .
Aiming at the problem that the traditional relational database management system can not satisfy the real-time application with the limited time affairs response and provides a highly reliable and highly available access service in the HLR of the mobile communication network, a real-time database and commercial Database combination of the realization of the model to provide high-capacity large transaction processing capabilities and high level of telecommunications-based real-time response to the service; analysis of the system based on transaction response time constraints priority concurrency control principles and the use of active trigger mechanism to solve data competition Method to realize .
