Abstract
With the development of the information era, the quantity of information increases in the way of geometric series, and people find that it is more and more difficult to obtain valuable informatin and it is incogitable to find out the rules hiding in the information. Data mining is a new technology to mine valuable informatin from abundant data, and association rules mining is a method of data mining. This paper elaborates on the process of the design and development of association rules mining system based on Apriori . The system is based upon classical Apriori arithmetic, and converts chinese medicine prescriptions database to a bitmap matrix, which greatly enhances the efficiency of search, and can mine frequent items and association rules respectively.
The paper is organized as following: Firstly, introduces the generation, definition and application of data mining; Secondly, sets forth the conception of association rules mining; Thirdly, analyzes the demand of the system, and propses the design project and implements the system; Finally, gives a test to mine chinese medicine groups from a chinese medicine prescriptions data, which proves the system valid and applicable.
Key words: Data mining; Apriori; Chinese traditional medicine
