| 摘 要： | 三维地籍是土地利用空间多元化的必然结果,是地籍多用途功能实现的必然要求。它将会在土地管理和社会经济发展规划中发挥重要的作用。但是动态的三维地籍数据结构复杂、数量大,给数据存储和管理带来极度不便,在一定程度上影响数据检索的效率。本文从了解ORACLE数据库的数据结构和管理方式出发,通过数据模型集成和联合索引存储分别对三维地籍数据库的数据结构和存储方式进行了优化,以达到提高数据检索效率的目的。

| Abstract: | The three-dimensional cadastre is an inevitable result of diversification of land use space,and an inevitable requirement for cadastral function to achieve multi requirements,which will be planned to play an important role in land management and social economic development.But with the complex organization and large quantity of the dynamic three-dimensional cadastral data,it gives an extreme incontinence for data storage as well as management manner of ORACLE database,and has influence the efficiency of dat... |
