Sparse dynamic selection trees

A device comprising:

• a memory device for storing a plurality of data nodes that include one or more data sets and one or more data objects, wherein each data set includes zero or more data objects and zero or more other data sets;
• and
• a processor coupled to the memory device and programmed to:
• depict a data set of interest as a primary node in an available data node area;
• depict one or more data nodes within the data set of interest as available data nodes within the available data node area;
• receive a selection of an available data node;
• depict the selected available data node as a selected data node in a selected data node area when the selected available data node is a data object;
• and
• depict the selected available data node in the available data node area as a secondary data node that is subordinate to the primary data node when the selected available data node is a data set.

One or more non-transitory computer-readable media having computer-executable instructions embodied thereon, wherein when executed by at least one processor, the computer-executable instructions cause the processor to:

• depict a data set of interest as a primary node in an available data node area;
• depict one or more data nodes within the data set of interest as available data nodes within the available data node area;
• receive a selection of an available data node;
• depict the selected available data node as a selected data node in a selected data node area when the selected available data node is a data object;
• and
• depict the selected available data node in the available data node area as a secondary data node that is subordinate to the primary data node when the selected available data node is a data set.
