Aiming at the demerits of the real-time database of configuration software, e.g. , real-time performance is not strong enough, and high cost in purchasing, with Visual C + + 6.0 as developing tool, the real-time database system (RTDBS) with better real-time performance is structured by adopting dynamic linkage library ( DLL). The system is combining traditional database system, compatible file system and memory database system, and multiple storage media. In addition, the variables of the real-time database are stored by using technology of object-oriented category. The implementing methods of data model and the open interface are given. The practical result shows that the RTDBS established here features higher real-time and open performance.%针对组态软件实时数据库的实时性不强、购买成本高等不利因素,以Visual C++6.0为开发工具,采用传统数据库系统、文件系统和内存数据库系统兼用、多种存储介质相结合的方式,以动态链接库技术构建了一种实时性较强的实时数据库系统.提出利用面向对象技术的类来存储实时数据库的变量,给出了数据模型和开放接口的实现方法.实际应用结果表明,建立的实时数据库系统具有较强的开放性与实时性.
