Data modeling for the data mart in the prediction system of specialty setting

It´s important to set up a basic database which can support national wide prediction system of specialty setting. With the challenges of massive and multi-source data, the key question we must solve is how to satisfy the users´ complex query demands in different levels and different angles. Based on the data warehouse theory and technology, we have taken an in-depth study of the data modeling of the data mart in the prediction system of specialty setting. In this paper, we describe a data modeling method for the prediction system of specialty setting, considering both the requirements and the reality. The study will be a guarantee of the research on the specialty setting prediction system.
