Workflow-oriented Data Mining System

Workflow is a series of action and process in operating affairData mining means a process of nontrivial extraction of implicit previously unknown and potentially useful information from data in database. Data mining provide good technology supportment for decision support system, and data mining tools can directly mining in large database for discovering potential knowledge in database.The mostly function of BCDAAS is decision analysis for decision梞aker. However, BCDAAS is based on the information technique of tradition at present .Decision analysis of Bank Card still belongs to data procession of manipulation type based on manipulational data. During using our BCDAAS,users bring forward the requirement of decision analysis , expect to develop intellectualized BCDAAS for decision action , such as assiting assignment center, sales promotion etc.The research object of this paper is developing data mining tools of intellectualized BCDAAS , for provicing important tools of data warehouse and decision surpportment.Vie design data mining tools based on three level structure of Clientj Server. Data source of the tools is based on Bank Card opration data source . This project contains three main module:data preparation, data mining, data presention.In data preparation module , adopt ODBC connection technique in order to connection all kinds of relationship database, which asures systemopenning . This paper discuss data structure of association rules: data structure of data preparation data source, data structure of mining result. In data mining module, this paper introduce four dataMining teehnique:association rules, Sequential, Patterns, classifiers,clustering. We mostly discuss association rules,and our improvementFor going deep into know about BCDAAS,we wholly discuss the status in quo, limitation and trend. This Bank Card data mining project is decision surpportment analysis tools based on Bank Card data source.
