Using Hierarchical Correlation Information To Signify Hierarchical Structure In A Single-Dimensional Stream

A method comprising:

• receiving, by a computing device, a request for output in a single dimension;
• generating, by the computing device, a query for a single-dimensional stream of data based on the request, the query including one or more values, wherein the single-dimensional stream of data is generated from multidimensional data;
• accessing, by the computing device, a hierarchical correlation information data structure using the query to determine hierarchical correlation information associated with the one or more values;
• using, by the computing device, a hierarchical structure from the hierarchical correlation information to generate a response that includes a portion of the single-dimensional stream of data, wherein the hierarchical correlation information signifies the hierarchical structure with respect to the portion of the single-dimensional stream of data;
• and
• outputting, by the computing device, the portion of the single-dimensional stream of data in the single dimension.

A computer readable storage medium having stored thereon program code executable by a computer system, the program code causing the computer system to:

• receive a request for output in a single dimension;
• generate a query for a single-dimensional stream of data based on the request, the query including one or more values, wherein the single-dimensional stream of data is generated from multidimensional data;
• access a hierarchical correlation information data structure using the query to determine hierarchical correlation information associated with the one or more values;
• use a hierarchical structure from the hierarchical correlation information to generate a response that includes a portion of the single-dimensional stream of data, wherein the hierarchical correlation information signifies the hierarchical structure with respect to the portion of the single-dimensional stream of data;
• and
• output the portion of the single-dimensional stream of data in the single dimension.
