过程数据的应用层次和数据获取研究

The studies for the process data's application layers and its acquiring

基于实时数据库和关系数据库,将过程数据的应用层次分成集成、整合和校正3个层次。用ODBC数据库绑定技术研究3个层次数据应用的建立方法和数据获取技术。用SQL、ASP等技术建立数据查询器、修正器和浏览器。提出基于实时数据库和关系数据库的数据集成实时数据库/数据整合批次关系数据库/数据校正有效数据库的过程数据应用层次模型。该研究对于企业信息化、装备信息管理、指挥与决策等系统的开发具有重要意义。

Three layers of process data's application,named as data integration,data batch process and data revising,is proposed in this paper.Based on ODBC data bending technology,the creating and data acquiring method for three layers' data applications are studied.The data query,data modify and data browse are designed with SQL and ASP.The process data application model based on real-time database and relational database is derived,which is consist of real-time database used as data integration,batch database used as data batch and virtual database used as data revise.The study is very meaningful to the development of enterprise information building,equipment information management and command and decision making.
