Research And Design Of Enterprise Information Resource Integration Platform

With the rapid development of computer technology, companies have established a largenumber of applications of information systems to help businesses deal with and manageinternal or external business. Because these systems are established at different timesaccording to the needs, they run independently from each other, it makes that the interactionof critical information between information systems is difficult to achieve, then forms aso-called "Information island". This leads the information resources use between the variousapplication systems to be difficult, the rise in the cost of running and low business operatingefficiency, and results in difficulty of optimize and efficient operation of enterprises, so thatthe degree of enterprise information construction is difficult to meet today’s increasinglycompetitive market. At this time, companies require an efficient, flexible, standardizedresource integration programs to meet the needs of enterprise information construction.For the problems of enterprise information construction and enterprise informationsystem application status, this paper presents the design goals of enterprise resourceintegration platform. Through a comprehensive study and research of the enterpriseapplication integration (EAI) technologies theory and key technologies of resource integration,including single sign-on (SSO), CAS protocol, Public Key Infrastructure (PKI), X.509digitalcertificates, Web Services, etc, this article puts forward the design scheme of integrationplatform, designs an integrated platform architecture, determines technology solutions of theinterface integration design and application integration design of the resource integrationplatform, and take a detailed design.The focus of this paper is to design single sign-portal and application integration ofenterprise information resource integration platform. The first is to achieve single sign-onportal, which provides users with a unified portal entrance and secure access controlmechanism. Through the analysis of mainstream single sign-on system solutions, at the sametime taking into account the cost of system development and platform adaptability, this articleuse the CAS protocol to achieve single sign-on portal design. For CAS SSO deficiencies, thisarticle use SSL authentication mechanism, designs security authentication module based onPKI and RBAC-based permission management module, creates a unified security accesscontrol platform, achieves a complete SSO mechanism; The second is the design of theapplication integration, which achieves design of a system application interface, thetransmission of information, the application program of interaction and other services. In theSelection of application integration technology, through the analysis of EAI technology,concludes that the traditional application integration solutions are proprietary and complex,therefore they can not achieve the necessary flexibility and adaptability. And due to the use of a series of standard protocols (Hypertext Transfer Protocol, Extensible Markup Language,Simple Object Access Protocol, Web Services Description Language, Universal DescriptionDiscovery and Integration, etc.), Web Services can effectively meet the requirements ofapplication integration and adaptability flexibility.Therefore, this paper chooses Web Servicesintegration technology to achieve application integration design of enterprise informationresource integration platform, and calls a consistent programming model of Web Services toachieve program interaction of integration platform.
