%X In this paper, we first briefly introduce the concepts of clickstream data and data warehouse, analyze two existing clickstream star schema-click star schema and session star schema in webhouse, then induce a new model-transaction star model based on them, and expressed the method of bringing out the model. Comparing with the two schemas mentioned above, its most apparent speciality is that it includes a series of meaningful page-view sequence rather than a single click. Thus, on the one hand it improves the query performance of data, on the other hand it is in favor of executing more deepen analysis-data mining, and simplifies the process of data pretreatment. At last,the paper verifies its' feasibility and validity using association rules based on the model.
