Design And Implementation Of Portal System For Integrated Information Managerment System

With the development of information technology, enterprise information portal system technology research has become a new hot spot, corporate enterprise information portal are the inevitable transformation of the strategic direction. Enterprise Information Portal (EIP, Enterprise Information Portal), are for the same value chain to provide public information related to the browser, as well as personalized access to internal information.Enterprise Information Portal is a window to display a corporate image, but also business visitors to obtain information outside of the interface, not only be able to dynamically publish enterprise storage at a variety of internal and external information, but also be able to support business applications, online office, as well as community forums and so on..Visitors can interact through the portal system of information and exchange of information on the distribution of enterprise storage for a variety of formats, a variety of sources of content (documents, data) unified retrieval, classification browser, and in accordance with permissions for access control and so on. In order to reduce enterprise software purchasing costs, the project used open source Liferay Portal system to replace expensive IBM Portal system, achieve the same OA, ERP, e-mail system such as information integration, a set of structures for small and medium enterprises integrated information management system portal system, the formation of a certain price advantage of the office products business.In this paper, the status of enterprise portal system and its technical rationale to study the current market on mainstream open source Portal system, an analysis of integrated information management system portal system, the overall scope of business models and specific business function, describes the system in Liferay Portal on basic set up an integrated information management system portal system technology architecture.. Integrated information management system portal system is set up at open-source Spring, Hibernate, Struts and Tiles and other components on the basis of the three-tier J2EE-based MVC structure, the formation of an integrated information management products gateway system architecture. This paper introduces the portal system is how to use these open source components of the industry's mainstream technology, the use of Spring and Hibernate data source management, transaction processing and data persistence, the use of Struts and Tiles implementation MVC three-tier structure, as well as through the Struts technology to Portlet development and deployment, making Portlet and its access to the management more convenient.In this paper, an integrated information management system portal system needs analysis, will the whole project is divided into a unified account with the organization and management, authentication authorization management, content management, unified interface display customization, collaboration tools, Application Integration seven modules, portal system and described the overall design idea and the detailed design of each module program. One of a unified account management and organization focuses on the design of the LDAP directory service, from the structure and mode of some aspects of the system's directory services.Finally this paper describes a unified account with the organization and management, certificate authority management, application system integration module and some other specific methods of implementation.
