| 摘 要： | 目前GML已成为空间数据编码、交换的国际标准,大量GML空间数据的不断涌现,给我们带来了新的挑战,即如何有效地管理、操纵这些GML格式的数据,如何建立良好的索引机制以高效地检索数据量大大增加的GML文档。本文结合开源纯面向对象数据库引擎db4o和传统的空间数据库技术,研究了GML空间数据的原生对象存储方法、索引机制。

| Abstract: | Presently GML has been the international standard for the encoding and exchange of spatial data. With the massive GML spatial data unceasing emergence, it brings us new challenges; how to effectually manage and manipulate these GML format data and how to build firstrate index mechanism to efficiently retrieve the GML document with larger data. Integrating the technology of db4o object-oriented database engine and traditional spatial database technology, this paper delved into the native object storage and index mechanism of GML spatial data. |
