The Design and Implementation of Distributed Logging Diagram System Based on WCF Technology

In this paper, a design plan of distributed logging diagram system based on the latest Windows communication foundation (WCF) technology is proposed, which can satisfy the demand on graphic drawing, data preparation and presentation of the logging drawing, and also is service-oriented. The server side services are designed as based on template architecture which could change database in configuration file. To satisfy the demand on performance, the large size core image files are transmitted by special images service. The client can realize image and data communication with the service application by using the TCP protocol. In practice, the design has solved the need of logging diagram, the problem of sharing data and the efficiency for upgrading system. The implementation of the logging diagram system also validates better expansibility, and works efficiency and compatibility than traditional C/S based graph diagram system of the enterprise.
