Abstract

A system, method, and computer program product are provided for generating a range of ordinals corresponding to key values represented in a B-Tree data structure. This allows for a boundary point, usable, for example, for partitioning the B-Tree for parallel processing, to be specified using an ordinal value of the range of ordinals. Then an ordinal-to-key transformation can be performed in order to identify a key value corresponding to the boundary point. Additionally, ordinal values can be identified through the use of key-to-ordinal transformations, allowing for specification of ranges, for example, in terms of key values.
