Design And Implementation Of Data Exchange Bus For Multi-Level Distributed Information System

The global information is highly developing now. Computer technology as well as network technology update rapidly. As the same time, the enterprises are also getting higher and higher to the request of the information transmission and information sharing. The information sharing between different entities has become the request and duty of the times. Traditional information system because of its mode of storage and access to data limitations, has gradually can not meet the actual demand. So, the research and utilization of distributed-platform as well as cross-platform development technology is one of the important tasks in information system construction. To realize the information transmission and sharing in distributed information system, data exchange is a key issue to be solved.A multi-level distributed information system has the Pyramid structure, in which a higher authority node has some subordinate nodes. Many kinds of data transfer forms exist in the system, including upper-lower level, same level and so on. There are different kinds of data formats and protocols as well. Data exchange includes transmission, control, receipt of message packages, and so on. The structure of system is complex. In the system, high stability, interfaces of good universality and good compatibility to different grade of service request are requested.The aim of this issue is to design and implement the data exchange bus for the multi-level distributed information system, to meet the needs of the system data exchange.Based on the analysis of the basis of background, main related technologies the data exchange bus involved are introduced first in this paper. Then, the function of the data exchange bus to be achieved and possible technical difficulties in actual project are analyzed. Finally, design and implementation of the data exchange bus in the system are given.
