The Design And Implementation Of Integrating Heterogeneous Information Platform Facing To Read-Only Application

With the development of advanced research in computing and communication, computer technology has been applied into transaction procession, information systems and workflow management in all kind of businesses. This development also leads to the revolution in the management model and new requirement in the emerging applications. For some special needs in global characteristics, it's necessary to integrate distributed, heterogeneous, autonomous and evolutional information components into a uniform platform, which has the transparent access mode for all these components.We firstly introduce the background and fundamental theory of Federated Information Systems (FIS) and N-tier application framework. Secondly we take Digital Archive Retrieval System (DARS) of Soochow University as an example to describe how these technologies have been used into the implement of the heterogeneous information integration platform. Furthermore, we discuss some themes about DARS, such as how to access information that stored in Domino/Notes, the methods to obtain information according to different components, distributed query,. etc. We also show the general application framework, which is deployed in DARS. The conclusion is given in the last part.
