【Abstract】 With Data Warehouse and Online Analytical Processing (OLAP), a Decision Support System for Foreign Investment Management is developed. Based on the design and implementation of the system, this paper illustrates the scheme of the Data Warehouse and the key techniques involved in the integration of foregrounding analysis application with OLAP service, including how to access the multi dimensional data in data cube and how to manage the meta data to control the OLAP server. From the perspectives of efficiency and flexibility, a glancing comparison on the performance of the analysis based on Data Warehouse and the analysis based on relational database are given at the end of the paper.更多还原
