| Abstract: | A rapid method of generating dynamic permission tree for Web database application is presented in this paper,which uses a range of integrated optimization techniques including the implementation of a TreeView component in client Web browser,the design of database tables supporting dynamic 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 effectively 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 current research findings,this method is proved a fast and efficient technology,which has a relatively high value for research and development. |
| Keywords: | dynamic permission tree TreeView integrated optimization load balance JavaScript programming language |
