Based On A Distributed Framework Of A Joint Portal System Research And Design

The enterprise portal is one kind of application software which develops in recent years, it may provide a sole visit enterprise kind of information resource for the enterprise the each entrance, enterprise's staff, the customer, the partner and the supplier and so on all may obtain the individuality information and the service through this portal. The enterprise portal may seamless integrate the enterprise the content, the commerce and the community. Through the enterprise portal, the enterprise can dynamic issue saves in the enterprise interior and exterior each kind of information, the enterprise portal also may support the on-line hypothesized community, the gateway user may mutually discuss and the exchange information.At present, the enterprise portal mostly uses the central portal construction. The enterprise portal value very major part manifests the application system which lies in it to connect, therefore the enterprise portal needs and in the enterprise all systems realization interconnection. But is day by day complex along with the enterprise information environment, this kind of central portal construction will be able to turn the enterprise information interactive frame the bottleneck. Therefore, at present the people proposed should establish based on the distributional construction cartel portal, the substitution tradition central portal, avoids the flaw of the traditional construction.Federated portals work because they share a common knowledge framework across all federated servers that use common object models and protocols for communication, primarily XML and LDAP. The common knowledge framework is a shared user directory structure called Digital Business Identity (DBI) and a cooperative metadata directory called the Knowledge Broker (KB). DBI maintains an identity record for each user and KB maintains metadata information about the various data and information sources available to users. Each server in the federation relies on these core components to determine which server can best meet user's requests for information or assistance.Based on the distributional skeleton Federated portals system will be the future enterprise to the information technology attention focal point, in the future several years based on the portal technology system will be able in the world scope the massive uses. Based on the distributional frame Federated portals, is authorized for the business agency takes responsibility organizes the system plan and the development meets their need the department portal, these department portals unions have composed enterprise's Federated portals system. Carries on the development take the department as the unit, makes the question which the system the donor project and budgets to be easier to process, simultaneously the portal goal and anticipated also can be clearer. Through by the department person in charge direct responsible way, the portal system may satisfy the user short-term or the long-term demand. May advance gradually the type development based on the distributional union frame portal system, the fast deployment and the better investment repayment rate. May reduce the donor project time based on the distributional construction model Federated portals.Mainly solves in the distributional Federated portals system following problem in the present paper:1) unites the unification authenticationportal system the unification authentication is refers to many information resource unification and so on the systems user account, password concentrates in the portal unification authentication center, each system makes the household authentication by the central data the only basis. The user may realize the Federated portals system through the corresponding connection to have the user account, the cryptographic information regarding correlation data operational channel sharing, simultaneously carries on various subsystems jurisdiction control through the appropriation module.2) electronic information exchangebecause in the Federated portals system each department level portal system is the independent system, moreover each department's application system also is mutually independent even isolates, simultaneously the request can carry on the data and the exchange of information in the Federated portals system with enterprise's outside information system. Therefore must solve the cross system data exchange problem in the Federated portals system..3) small and middle enterprise the low cost solutionwe discussed the Federated portals system in small and middle enterprise application demand, therefore is restricted in small and middle enterprise the limited fund investment, how and constructs the Federated portals system from the economical angle choice which small and middle enterprise may withstand is needs to discuss and to solve the question.The paper proposed based on the content integration Federated portals overhead construction. Uses the content management system management system in the Federated portals system to take the entire construction the core, may the low cost fast development individuality department portal pitch point. Simultaneously has studied in the Federated portals system the skeleton expandable application system and the portal pitch point interactive way, proposed one kind of conformity data exchange system and the portal pitch point frame and the method.In the research Federated portals system content management and in the data exchange frame foundation, the paper has first analyzed the Federated portals system to the user status management special request, proposed registers the plan based on the unification status authentication system simple point, simultaneously compared the disperser to authenticate and to unify authenticates has the shortcoming, elaborated realized the SSO basic principle of work, chose the LID frame to take the realization unification status authentication the foundation. After that the multianalysis user authentication system request, introduced based on LID the frame OpenID solution situation, as well as work flow. Finally the detailed introduction in the standard WEB environment, erects the OpenID server the method and the concrete realization module, was meeting the dissect based on the OpenID frame customer end realization method and the conformity module.
