基于树形结构的数据检索方式研究

A New Way of Data Retrieving Based on TreeView

分析了信息系统中传统数据检索方式的不足,结合一个具体的学生信息管理系统的概念模型, 介绍了基于树形结构的数据检索算法及其在软件开发中的应用,并给出其示例界面,最后用PowerBuilder实 现了这个系统的树形结构。

Based on analyzing the defaults of traditional way of data retrieving, the paper introduces the data retrieving algorithm based on treeview and its application in software developing, gives the example interface by combining the conceptual model of a MIS about student. At last, the algorithm is achieved by PowerBuilder language.
