为满足配电自动化系统对实时数据库的各种应用需求 ,开发了一个跨平台、可伸缩、接口丰富的对象关系实时数据库系统 RTDB4DA。文中介绍了该实时数据库中内存管理、事务管理、数据恢复和查询优化等核心部分的开发思路 ;对 RTDB4DA提供的 3种接口 (C++接口、ADO接口和JDBC接口 )的实现、优缺点和适用情况进行了比较详细的论述
In order to meet various application requirements of real-time database for distribution automation system, a cross-platform, scalable and interface-rich real-time object database RTDB4DA was developed. This paper introduces the core idea of memory management, transaction management, data recovery and query optimization in this real-time database. The implementation, advantages, disadvantages and applicability of the three interfaces provided by RTDB4DA (C ++ interface, ADO interface and JDBC interface) Conducted a more detailed discussion
