Design And Implementation Of The Protocol Parser In Data Exchange Management System

More and more enterprises are trying to go after be win-win by sharing informationwith each other in the opening global market. In the same way, the government canwork together more efficiently. So, the support has grown for data exchange products.However, the data exchange products are different from the normal information systemsbecause they are made based on the existed information systems. During designing,they have a common problem: heterogeneous data.The project of data exchange management system for Shenyang Administration ofWork Safety is also faced with this problem. This paper was put forward to solve theheterogeneous data problem.In this paper I analyzed the theory and technology using in data exchange products.At the same time, some excellent methods and theory were borrowed in my design.After having a research on the whole structure of the system, the formalizationdescription was used to describe the process of data exchange. So the content of theprotocol parser and the environment of it are definite. The design of data exchangeprotocol was to solve the heterogeneous data problem in our project. For this protocol,the methods of visual management and parsing were designed. And the method ofparsing is the design of the protocol parser which including the module of checkingprotocol, visit control, parsing data and so on. The project was implemented based onthe above designs. At last, the test for protocol conformance and integration testing weredone to prove that this subject was valuable.
