【Abstract】 The construction of the Decision Supporting System (DSS) for a new car design based on the vast amount of history cases is very important to the car virtual manufacturing. The conjunction of the Data Warehousing (DW), On-Line Analytical Processing (OLAP) and Data Mining (DM) is an effective way. This paper presents a kind of architecture of the DSS for the car design, describes the main modeling steps and key data structure for a Data Warehousing. Finally, an application logic model of the data warehouse is built up.更多还原
