摘要
多维数据库的应用日益广泛 ,如何有效地存储组织多维的数据 ,提高多维数据处理的效率已成为一个核心问题。对空间数据库索引技术的研究情况作了分析 ,介绍了各类技术的基本思想。最后着重介绍了一种用于高维特征向量检索的新的、通用的空间索引技术 。
With the wide application of high dimensional database,how to store and organize high dimensional data is becoming more and more crucial for efficient processing in high dimensional database In this paper,existing spatial indexing techniques are divided into four classes and the basic idea of each class is summarized Finally,an universal spatial indexing technic is put forward for the retrieval of high dimensional feature vectors called the generalized R tree
