摘　　要：文章提出一种基于数据库生成动态Web权限树的快速方法,采用了一系列综合优化技术,如客户端浏览器的Web树形显现组件实现,支持动态权限分配的数据表设计以及对数据库一次访问实现权限树快速生成的算法。该方法合理分配了计算单元之间的运算负载,有效降低了通信交互和等待时间,并注重采用高效算法充分挖掘每个计算单元的潜力。该方法在DAG系统的开发中达到了满意的工程应用效果;与当前的相关研究成果的全面对比表明,该方法快速高效,具有理论参考和工程借鉴价值。A rapid method of generating dynamic permission tree for Web database application is pres- ented in this paper, which uses a range of integrated optimization techniques including the implemen- tation of a TreeView component in client Web browser, the design of database tables supporting dy- namic rights allocation, and the rapid algorithm of generating permission tree through a single visit to the database. By allocating reasonable computational load among computing units, this method effec- tively reduces the waiting time for interaction and communication, and also takes efficient algorithms to fully tap the potential of each computing unit. The method has been adopted in the development of DAG system, and has reached a satisfying engineering effect. Through the overall comparison to cur- rent research findings, this method is proved a fast and efficient technology, which has a relatively high value for research and development.
