Research and Application on OLAP-based Farm Products Examination Model

The technology of Data Warehouse is being widely used in decision making and data analysis. Data Warehouse generalizes and consolidates multidimensional (MD) data. Hence, Data Warehouse has become an important platform for OLAP which is based on a AM data model. Therefore, dimensional modeling is a key factor in OLAP data analysis. In this paper, we address the technology of dimensional modeling based on Data Warehouse. Based on the technologv of dimensional modeling, we integrate the characters of farm product transaction market in China and take the farm product examination as the subject of data analysis. Then the packet graphic and snowflake schema of farm product examination are designed. Finally, the paper offers the results of the OLAP with farm product examination model.
