System Design And Realization Of Enterprise's Internal Portal

As the enterprise's development and construction, Growth in demand for enterprise's operations to use the information technology means to transmit information. Construct a large number of multi-types of information systems. While the enterprise's operating costs are greatly reduced, greatly enhance the operational efficiency. At this time, we have partial function in those with automated systems, known as the information silos. At this time, the system relatively independent business executives have brought the situation to the lack of a unified decision-making information concerns, but also for system integration applications bring some difficulties. As the business operations of information systems requires the elimination of information silos increasingly urgent need to improve work efficiency and enterprise macro accuracy and timeliness of decision-making, enterprise portals have emerged as an integration framework and rapid development, to provide enterprises with a more complete solution.Specifically within the enterprise portal has the following significant effects: the elimination of information silos, improve productivity and enterprise macro decision-making accuracy and timeliness of all aspects of the enterprise and the different dimensions of information slicing integrated, organic way, real-time displayed in the user front, convenient for routine administration and macro-decision-making; streamlining links, quick to adapt to new business and new strategy needs, by providing a single sign-on capabilities, simplifying the user access to a variety of application systems link, thereby improving the efficiency ; browser-based approach, unified access and display interface to provide single sign-on function, and with the remote desktop management system to reduce the burden of corporate governance also meet the needs of IT-based support system development.Portal a key technology is to realize the right covers the application of single sign-on. SSO (Single Sign-On, Single Sign-On) is the identity management part of it. SSO in a more popular definition is: SSO refers to the different applications access the same server, the protected resources in the same user, only need to log in once, through an application of the security validation, and then access other protected applications resources, no longer need to re-login authentication.This article focuses on how portal technology and portal system application to build ideas, in order to build in Jilin Branch of China Unicom to build the system within the portal as an example, research within the enterprise portal design and practical application in the design and use.Jilin Unicom of China Unicom Group, according to its own development, to deploy with the requirements of the actual situation, designed and built a house in Jilin Unicom portal. China Unicom to establish a unified enterprise portal platform for the whole company staff interaction, learning and facilitate the establishment and dissemination of corporate culture to promote the information resources of various categories of China Unicom, the unified, centralized management, and give full play to corporate information resources, effect. The use of information technology tools to help enterprises to obtain a strategic advantage, improve efficiency and effectiveness.Through enterprise portals within the framework of the system, and constantly promote the enterprise information system construction specification management, and information resources to facilitate effective, fast show, provide to the user. Jilin Unicom portal integration within the enterprise portal development, covering all the necessary systems, such as, corporate office automation (OA) systems, enterprise resource planning management system (ERP), China Unicom Group, unified messaging systems, Jilin Unicom electronic records management system, business operations analysis system, internal performance appraisal system, task management system applications. At present the system is in the design development phase, this paper, the portal system in the practical application of the construction process need to take into account all aspects of the portal system, the construction and application of the study and discussion.Jilin Unicom function of the system within the enterprise portal architecture can be divided into the portal application management, user management and a unified certification system management of three parts. It is covered by the system in accordance with the portal user directory. User management system account management platform, authentication gateways, portals and application of the theory of system construction and other services. With customers, access, display, application of four-level technical architecture modeling, the user directory system (LDAP) as an enterprise information management system, the user master data source, by the authentication gateway to complete user authentication and application access authorization, integrated enterprise information systems within the major, using IBM WebSphere Protal technology system development.Portal application management to achieve some of the major show of basic services layer of management and portal capabilities, user management and a unified user management to achieve some of the major authentication, unified authentication and single sign-on capabilities, system management to achieve some of the major system permissions management, system security management, operation Log Management, system maintenance and application integration management. The project portal, including a national contacts, to-do to be read, information gathering, messaging services, and other basic applications. User directory user management module is responsible for the management of users and organizations, including user directory management, user rights management make self-help. User authentication provides a single point of access to the portal authentication and rights management. User data maintenance, according to the user types, user management in the operation of authority are also different. Internal users from HR systems, this part of the user data, add, delete, and HR synchronized to the national directory of user data attributes updates are synchronized with the way the data from the HR system operation, all external users to add, delete, update, and internal users In addition to HR system synchronization to update the national inventory of properties other than through the user management operations.User authentication and authorization of portal system is to complete the main gateway from the certification. Certification of user access gateway is as a focal point to receive the user's access request, the proxy user access to back-related applications. User authentication and authorization strategy for the main process, including through the establishment of user accounts to access the application system sub-account, thereby granting the user access to the application system.Jilin Unicom at this stage has been achieved within the portal system, the contents of the application system integration, user management integration and achieving the door-to-use applications, single sign-on and personalized configuration, but each business process is still in separate systems the transfer of the business integration between, with a seamless interface between the processes still need to invest a lot of research and construction.The implementation of the portal-building process, we need to recognize the importance of systematic planning, when we sort out the development goals, needs careful analysis in order to make consistent with the needs of enterprise development, quality information products.
