数据仓库技术在放射性监测系统中的应用研究

针对目前核辐射安全防护还停留在基于以事务处理为主的数据库管理系统之上的传统数据分析，文章提出了在放射性监测系统中建立以分析处理为主的数据仓库体系化环境。初步设计了系统的总体框架，完成了数据仓库的建模过程。重点在于确定主题、粒度划分和多维数据模型的确立。同时运用数据挖掘工具对其数据进行模式和知识的发现。

The Application and Research of Data Warehouse Technology in Radioactivity Monitoring System

The current condition of safe protection from radiation stays on the traditional data analysis of DBMS based on the business transaction,we expound to set up systematic environment of data warehouse based on the analysis transaction in the radioactivity monitoring system. We design the whole primary framework and accomplish the process of modeling. The emphasis is on establishing subject and multidimensional data pattern. At the same time we use data mining tool to discover data pattern and knowledge.
