摘要
OLAP是数据仓库的一个最典型的应用,它能够展现多维数据视图。同时,还提供了较直观的多维分析操作,使得能够多角度、多层次地观察数据仓库中的数据。介绍了OLAP技术的特征和概念,分析研究了运用ADOMD建立OLAP决策支持系统的关键技术,并以某大型斜拉桥的长期健康监测数据系统为研究背景,给出了桥梁健康监测OLAP系统的设计方案。
On-line analytical processing （OLAP） is a classical application of data warehousing for the interactive analysis of multidimensional data of varied granularities. Moreover, OLAP supports some multidimensional analytical operations, such as ,slice,dice,roll-up,drill-down and rotate, which provide users with the flexibility to view data from different perspectives. This paper introduced the characters and concept of data warehouse and OLAP. The OLAP system based an ADO MD was studied. The design schema of OLAP system for bridge healthy monitoring system of one large-scale bridge was given.
