| 摘 要： | 提出了基于面向对象技术和Ｒ树索引结构的航海资料数据模型。它通过面向对象技术的继承性有效地解决了信息存储的冗余问题，体现了航海资料的自然层次结构，与航海人员的思维定式相吻合。同时，通过Ｒ树建立了航海资料二维动态索引，实现了航海信息快速的查询。

| Abstract: | This paper presents a model of the navigation information based on the object oriented programming technology and R Tree. The model avoids the redundant problem of the navigation information in the integrated navigation system, represents a very natural way of thinking and reasoning, and demonstrates the simplicity and understandability that are needed for mariners. In other respect, the paper builds up a two dimension dynamic index for requiring navigation information. |
