Research And Implement Of Key Technology For Digital Campus

According to the goal of digital campus construction, the existing isomerism of subsystems resulted in difficult to carry out with interconnecting for different systems, data sharing cannot come true, data redundancy apparent, and it is far from the construction standards of digital campus greatly. Must be through the comprehensive integrated way of building comprehensive platform based on web service, make each department work together, and give full play to the role of the existing system resources.Due to the differences of the structure between the systems, in order to achieve the construction goal, it is necessary to analyse the structure of database of existing system, accomplish the comprehensive integration of the network from data, applications and services, this thesis puts forward a kind of integrated solutions based on web service to solve the problem of network application, and the problem of isomerism between the data and systems. In order to shielding platform isomerism, the mode based on the Web service is adopted, so that can be used for packaging and release, construct general middle layer, eliminate the obstacles of data sharing, thus forming a integrated system platform based on Web service.The thesis adopts the combination method with J2 EE and web service to implement application integration with distributed multi-layer structure. For hardware, operating system and database system platform, constructing an open, easy to expand application framework, and provide the standard interface and flexible configuration function, and has the characteristics of the component type expansion. It provides a loose coupling interface to realize the unity of the network resources to visit with Web service mode for different systems. Through the data cleaning, data extraction, data integration, and other means to realize data integration and sharing, and forms the corresponding database, updates the relevant data, to ensure the data consistency and integrity.In this thesis, the research on LDAP based single sign-on technique and its realization are studied, the user information and the specific application are relative independence, both provides convenience for the users, and ensure data security, while strengthening the ability of network management.
