Design And Implementation Of Data Integration Platform Oriented To The Shared Database Center

With the development of the computer, communication and network technology, and the huge and immense impact on the whole world brought by the globalization and internationalization, the process of informationization and digitization of the whole society is accelerated greatly, Meanwhile, the information systems which enterprises or universities set up in different periods have formed the"Isolated Information Island". Data integration is the most effective method to break through the "information isolated island". For this sake, this thesis designs and implements a data integration platform oriented to the shared database center.Firstly, this paper gives an introduction about the technical background of this thesis and the applied background of the digitalized campus. Secondly, it analyses the requirements of the shared database center, and puts forward the main framework and the organizational structure of the shared platform. Based on the profound analyses of the structure, the paper takes ERwin as the modeling tool, divides the data layer of platform into five subject areas to analyze, and develops the relevant tools. Then, the paper summarizes and analyzes the relevant technology of the data exchange, and presents the conception of the data exchange protocol. Afterwards, based on the monitor mechanism, the paper proposes a data exchange scheme, and designs and implements the various modules. In the end, it draws a conclusion about some characteristics and modified suggestions of the shared platform.The shared platform in this paper has already been partially applied in one university's digitalized campus construction. The fact shows the platform not only has...
