Research And Implementation Of The Management System For Internet-based Integrated Laboratory

As a link between the client and the server, and the manager of user and experimental information, the management system is apparently the core of the "Virtual and Physical Interaged Network Laboratory" system platform.This thesis focuses on the design and implementation of the management system and has finished the requirement analysis, overall design, and system development. The detailed functional model in user management, laboratory management and teaching management, as well as the six hierarchy role model of the management system have been obtained based on remote experiment teaching tasks and network laboratory development needs. According to the topology of existing physical and virtual experiment system and the comparison between B/S and C/S development mode, a B/S/C architecture of the integrated network laboratory and3-tier development model of its management system are determined to bring good system scalability. At the same time, MySQL is selected as the practical database of the management system and ER model is used as the standardization method to accomplish the design of the database schema, in order to bring high system performance and also try to meet the requirements of3-paradigms. Finally, the design and implementation process of the management system is explained in detail, the tiered development with help of the SSH2framework is completed, and design patterns like MVC and interface-oriented programming are adopted to decouple system modules and ensure good scalability and maintainability for the management system. As for the security, the system has achieved a method level fine-grained privilege management strategy by using RBAC model and Shiro security framework, which has excellent practicality and versatility.
