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.
