Design And Implementation Of Silver Interconnect Systems Based On Web Services Tax Library

The work of this paper aims to design and realize an application of enterprise application integration(EAI)scheme in the heterogeneous system integration of the tax,exchequer, banks, which can combine the existing information resources , and break the information barrier between different departments. The main task of the works is the design and analyse of the system.On the basis of the present application system of the tax, exchequer, commercial bank, the paper design and realize an application platform which is trans-departmentally, inter-tradly, information sharing, and data interoperating.the platform can make the systems which are developed by different departments, develop tools and based on defferent dadabase, application platform , become a whole part .Because of the commonability , platform and language independence of web services, web services has become one of the best schemes to realize the information system that the tax , exchequer , commercial banks communicate with each other.web services is a service-oriented architecture, It merits are that it can construct a common use technology layer of platform-independent and language-independent, on the basis of which various kinds of existing platforms are connected and intergrated.This paper focuses on the research of design and realization of the application of enterprise application integration(EAI)in the heterogeneous system integration, on the basis of the technology of workflow and web servives, and illustrates the research of design idea and the design structure of information system that the tax, exchequer, commercial bank communicate with each other, and then bring out the solution scheme. Based on the web services characteristic and aiming at the national tax, the exchequer and various commercial banks system present correlation software system relations, it creates a feasible solution. In order to improve systematic function, it gives the theory scheme of compressing soap message . In order to satisfy the requirements of long-lived transaction in web services, the paper design the algorithm for dynamically sliding windows to resolve long-lived transaction.This article introduce the correlative technology of the EAI and the fundmential theory , espelially illustrates the workflow technology based on web services , Then based on the security of web services ,using ws-security and WSE ,design and construct the scurity scheme of the tax, exchequer .banks interlinkage , which is based on xml encryption and digital signature.
