Based On The Knowledge Of J2ee Architecture Found In The Crm System

The competition of enterprises are focus on the customers just like the quantity, price and management before. For making good use of customer resource, CRM system is necessary. With the development of modern data process and analysis technology, CRM system is optimized.According to the application of the KDD (Knowledge Discovery in Database) technology in CRM research the thesis firstly introduced the current situation of the KDD technology, then in the basis of the system request and data characteristic of the technology used in CRM design, pointed out the common application demand and surrounding of the CRM application. At the same time, it also provided how to design the system, analyzed the common algorithm of the associate rule used in the customer analysis. To improvement the shortcoming of the traditional arithmetic and make good use of customer information, it ameliorated the Apriori algorithm of association rules and analysed the temporal and spacial complexity to enhance the analysis of customer invest trend.More and more systems move to the 3—tier or multi—tier system because the latter one shows better in scalability and reusability together . Web technology is also adapted by more CRM system. For making good use of KDD technology in CRM system, the thesis presents J2EE—based system architecture, adapts the Model—View—Controller(MVC) patter.These make the whole system become a multi—tier component system, loose—couple horizontally and vertically, Provide flexibility, reusability, testability and extensibility. To improve the efficiently of the system, design patterns are used to optimize system's performance, so the target of mining the customer information by KDD technology is realized.
