Research On Workflow Based Information Integration And It's Application On Customer Information Management

In the age of Knowledge Economics and Network Information , the role of information in our society is becoming more and more important. How to integrate and utilize information supplied by management information system in a reusable and dynamic way without restraint of time and space is a challenge to knowledge workers and system integration workers now. In this thesis, after an overview of current traditional Information Integration research in the field of Computer Science,the fundamental of Information Integration and Workflow Technology are first introduced. On the basis of a deep research into the pivotal technology of Information Integration based on Workflow Technology ,the architecture of a Information Integration System based on Workflow is designed by combining the Web Service technology, Workflow technology and XML technology. Then the pivotal theory of working and the process of developing system are discussed in detail. Towards the end of the thesis,a case is studied to show how to apply the Workflow based Information Integration System to Customer Information Management System in the Wuxi Jixing Integrated Cooperate Management System. The system has four layers in this system which includes from bottom to top Data Layer,Services Integration Layer,control Layer and User Interface Layer. Different information and process to obtain them are transformed into sharing Services by Web Services technology,and then they are integrated into various application systems in a reusable way. Workflow Based,Information Service object and dynamic call of Web Service are developed through Object-Oriented and Reuse-Oriented methods.
