一种高效的基于关系模型的树结构可视化管理方法

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

常见的基于关系模型的树结构数据的建树时间复杂度为O(n2),当树的规模较大时,显示树数据的响应时间较长,影响用户的使用效率。针对该问题,本文设计并实现了一种基于关系模型的树数据存储结构,研究并实现了一种高效的基于关系模型的树结构数据可视化管理的方法。实际应用表明,该方法简单易实现,有较好的时间性能和应用价值。

Commonly the complexity of tree time of tree-structured data based on relational model is O（n^2）. 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.
