摘　　要：在研究实时数据库理论的基础上,分析了当前主流工业实时数据库功能及外部应用环境和条件的变化,结合最新的信息技术,设计了一种新的面向需求的实时数据库数据管理模型,提出了流程工业实时数据库位号映射技术和基于STL技术的多层次索引建立的方法,同时采用COM/DCOM技术使系统支持分布式应用,利用这种数据管理模型设计开发了实时数据库软件APC-iSYS,经运行验证了该模型的有效性和优越性.The data model theory of real-time database and data characteristics of the processing industry is studied. Then by employing the latest information technology, a new design method for data management of the processing industry's real-time database is presented for the processing enterprises' application of real-time database. In the data model, data from the processing enterprise is organized by tag mapping technology. The model has a fast query system with multi-layer indexing structure by using STL (standard template library). In addition, the data model support distributed computation in the processing enterprises by adopting COM/DCOM (distributed component object model) technology. The validity and feasibility of the presented design method were proved by the method's successful application in the real-time database software of APC-iSYS.
