A High Efficient Method of Visualization Management Based on Tree Structure of Relational Model

PAN Jie-zhu(Department of Computer Science and Technology,Anhui Institute of Education,Hefei 230061,China)  
Commonly the complexity of tree time of tree-structured data based on relational model is O(n2).When the scale of tree becomes larger,the response time to display tree-structured data is longer,which will affect the using efficiency of the users.Therefore,this paper proposes the storage structure of tree data based on relational model,and studies and implements a high efficient method of visualization management based on tree structure of relational model.The experiments prove that this method is simple to implement,and has a better time performance and practical value.
