Police Through Server Software System Based On The Corba Model

The Implement of a Jinwutong Server Software System Based on the Model of CORE AMajor: Control Theory and Control Engineering Graduate: Wang Jue Advisor: Huang SanRecently the application of distributed computing becomes in common use. But the conventional Client/Server model can not meet the need of modern computing. International organization OMG presents the CORBA standard. The CORBA standard provides the interface for the different applications. It divides the Client and Server completely, and adds a new tier-agent between the Client and the Server. Because of these changes CORBA ameliorates the C/S method and improves the distributed computing greatly.With the development of technology, PDA has been put into practice use. But PDA has still some problems when it is used in the police work, especially in operating the heterogeneous database. Using CORBA concepts our scheme presents a new way to solve these problems. We develop a Jingwutong Server software system based on the model of CORBA. The Jingwutong system extracts data from the system database and after handling them it downloads the data into PDA. It also receives the data upload from PDA and put the converted data into the system database. The system is a agent and gives a interface for the data exchanging between the system database and PDA. The scheme can resolve the troubles in convenience, security and the using in heterogeneous environment. This paper introduces the design method, the architecture, the functions and the plan of Implement of this software system.
