【正文】 ld financial institutions to provide us with these data, and our goal is to acquisition of these data, and maintain data integrity and accuracy of this system is our main function.We adopt a program approach to achieve such a data collection, and does not require manual intervention, this set of systems used c language, and the threetier structure itself to do some design features a more detailed analysis, and a large number of XML technology, The threetier system designed to achieve a relatively plete set of features and has a good user interface and scalability of the system. In this paper also on the point on innovation, and the prospect of automated data collection and data mining direction for the development and prospects.Key words: fund, XML, data mining.III / 49目 錄1
