Web-based Olap Visualization Methods

OLAP is a Software technology which let analysiser, manager or executercan deposit and extract the information consistently, interactively from different point, thus can go deep into the data. In the dataware appliance, OLAP appliance is a former tool of dataware appliance..NET is Microsoft's XML Web service platform. XML Web service can let application program transfers and share data leap over operating systemand program language on the Internet.OLAP technology combined with. NET technology can construct a On-Line Analytical Processing service based Internet.This thesis does a research on how to realize visualization of OLAP, which is a front display system based on Web. The task of this subject is to design an analysis and front display system which can slice, dice, drill, and pivot muti-dimesion dataset.Firstly, this thesis expound the current development situation and key technologies about data warehouse and OLAP. Then it discusses the overall plan of analysis platform, developing environment and key technologies from the aspects of generality and practicality of the system, and focuses on the design of data forms. Finally, the realization of the system and its effect are analyzed.At present, this system has achieved good test results and demonstrates the correctness and teasibility of the system.
