Abstract :
With the development of information technology, the government become increasingly demanding of information technology. Therefore, it also brings some problems, due to heterogeneous databases and heterogeneous application systems, lead to each application system to become an “information isolated island”. An effective solution is using the method of information integration and data exchange as well as using EJB technology to realize the transparent exchange between the isomerism databases and processing of distributional data. Therefore, we take E-Switch as the application background to introduce the E-Switch computation model in the EDI(Electronic Data Interchange) platform and system structure as well as its function characteristics. The E-Switch platform can achieve the access services of application system, the data forwarding, internal information processing (routing processing, compression/ decompression, encryption/decryption, pack/unpacking, information analysis and classification, data filtering/distribution, storage and so on), public data maintenance, system configuration management, information statistics, system monitoring and so on.
