The Architecture And Application Of Data Warehouse Based On Chronic Diseases

Chronic diseases refers to those morbidity, disability and mortality is high, the hospitallizat--ion cost is expensive, long-term cannot be self-healing, and almost cannot almost heal by oneself either, but disease with a clear preventive and control measures. Identify the factors that affect the incidence of chronic disease, thus prevention is the major chronic disease prevention and effective means.This paper based on a deep understanding of the theory of Data Warehouse and architecture and construction methodology. And The Data Warehouse technologies are applied to business data analysis of chronic diseases by author firstly. However, due to the special nature of the business of chronic diseases, the users of chronic disease data warehouse have special needs, Such as the need to keep in the data warehouse system by adding new data sources, Of course, the data source also has a range of features, including the definition of many data elements, the different types of business systems, the complex structures of the data sources. Which also makes traditional data warehouse architecture and architectural approach can not effectively adapt to chronic disease data warehouse construction. In this subject, the author adds the central library components to the original architecture of the Data warehouse. The addition of the component solve the problem that arised from the construction of chronic disease data warehouse. Add the component will not only make joining the chronic diseases data sources into the Data warehouse system has become easier,but also greatly facilitate the process of data warehouse architecture.
