    • A system provides multidimensional tuple Hilbert ordering within a linear storage structure to enable more consistent and efficient access to stored multidimensional tuples. The database system comprises a tuple storage module that receives multidimensional data elements, where each multidimensional data element is defined by a plurality of different object types, and where each object is associated with a different dimension within a multidimensional data space. The tuple storage module further forms a respective tuple for each of the multidimensional data elements by mapping each object to an associated reference and applies a Hilbert function to the references of each of the tuples to determine a respective Hilbert ordering for each of the tuples. The system further comprises a linear data storage structure that includes a B-tree for storing the Hilbert ordering.
    • 系统提供线性存储结构内的多维元组希尔伯特排序,以便更加一致和高效地访问存储的多维元组。 数据库系统包括接收多维数据元素的元组存储模块,其中每个多维数据元素由多个不同的对象类型定义,并且其中每个对象与多维数据空间内的不同维度相关联。 元组存储模块还通过将每个对象映射到相关联的引用来形成用于每个多维数据元素的相应元组,并且将希尔伯特函数应用于每个元组的引用以确定每个元组的相应希尔伯特排序。 该系统还包括线性数据存储结构,其包括用于存储希尔伯特排序的B树。
