Digital Organism System User Information Management System Design And Realization

With the Internet network and computing technology in-depth development ,distributed systems has been widely applied. Distributed System will be adopted on the geographic distribution of heterogeneous resources into a complete computing platform, the efficient resouces management system has become the digital organisms most pressing problem. This is necessary to consider some of the core of General Services, including resource discovery, detection, resource scheduling and the selecte-matching problem of resouce and task. At the same time, we also have the necessary to pay special attention to the reliability, availability, and dynamic management of existed resouces in system. The management system based on digital organisms system is studying how to make efficient management to these resouces integrated in the wide-area Internet through a broadband Internet digital organisms,and this article is to describe the management of user information. This thesis first introduces the topic of research background and significance, then the digital organisms system are briefly described, and then combined with the engineering practice of user information management system using the following key design:1. The article take theoretical analysis of user information management system from the view of system point, set up a unified model and put forward a unified management interface for scalable management demand and the ways of access,convenience of the administrator to the user management.2. When the administrators to manage users, this thesis designed a user and user group information cache in order to improve query speed to the user information, so to some extent alleviate the load on the server node in system,and saving network bandwidth.3. In this thesis, a specific algorithm are applied to the user's authentication password and authentication information which is stored in the syestem with segmented and distributed way, and provides a redundancy mechanism it greatly enhanced the system security.Through extensive testing to verify the system reliability and correctness of implementation and achieve the goal of safe, efficient, dynamic manage digital organisms user information .
