Autonomous Domain Of Heterogeneous Information-based Collaborative Mechanism Research And Application

The integration, exchange, and sharing of information between network information systems have become the development trend. Nowadays system integration usually adopts CORBA and XML technology, while the system is not flexible. Multi-system data synchronization and sharing mostly use the synchronization program of enterprise database which is lack of general usage. And the multi-system is always instability. So this paper designs a heterogeneous information cooperative mechanism to resolve these problems.This paper researchs on the Asynchronous Message Mechanism, combining the distributed character of Heterogeneous System to design a WAN message mechanism based on Web service and defining the processor for the generation, adapter, process and remote send of message. Considering the randomicity of heterogeneous information in distributed information systems, a new message mechanism, heterogeneous information cooperative mechanism based on self-governing domain, has been established. The mechanism adopts Web services to get interconnectted between information systems, uses custom message mechanism to achieve information conversion in heterogeneous systems, which can avoid information inconsistent, information loss, and information redundancy, and takes subscribe/published pattern dynamically organize the logical structure between systems to solve the close-coupled of function and structure. This paper studies relational database, sets different database objects for different databases to achieve database information standardization handling, and projects cooperative processing of self-governing domain information. Some studies have been done on grid resource management to design resource management mechanism and auxiliary mechanism in self-government domain. To resolve both the asynchronous send and handling of cooperative information and long wait of Web task, Web asynchronous task management based on log has been projected to achieve priority-queue task scheduler. Periodic task management model has also been designed to restore the effectiveness of cooperative information.In the end, this paper has analysed the operation and organization of existing experts information system, and used heterogeneous information cooperative mechanism to construct the prototyping service platform of national experts information.
