基于面向对象空间数据库的空间对象模型设计及其存储策略的探讨

A Research for Designing and Storing the Spatial Object Model Based on OODBS

分析空间信息的结构和面向对象数据库技术的基础上,着重讨论了如何利用面向对象数据库的技术来对空间信息进行存储,展现了利用面向对象设计建立空间信息结构模型的先进性,并针对空间信息的结构提出了在面向对象空间数据库的存储策略。一方面为面向对象空间数据库的设计与建立提供参考,另一方面,通过借鉴相对成熟的面向对象技术,为空间信息的存储管理提供了思路和策略。

The author discusses how to store and manage the spatial object model by analyzing the construction of spatial information and the technology of the object--oriented database （OODBS）. It takes advantage of the object--oriented design for spatial object model and then presents three strategies fr storing the model base on the technology of OODBS. The author has the goal of providing an example of designing and building the OODBS. Moreover, the author presents an idea and approach to store and manage the spatial dada by referring to the technology of OODBS which has been studied wide.
