Abstract
A binary data file embodies an inline tree data structure storing fields of a hierarchical dataset. The inline tree comprises first-level binary string segments, each comprising substantially contiguous second-level binary string segments, corresponding to subranges of first and second subsets of data fields. Size is reduced by substituting: binary string indices for alphanumeric strings; a data clump index for a set of correlated/anticorrelated strings; field masks for unoccupied data fields. A dedicated conversion program generates the inline tree from conventional database formats, which is read entirely into RAM to be searched/filtered by a dedicated search/filter program. Small size (<2 bytes/field/record) and contiguous arrangement enables searching/filtering of >10records (>100 data fields) in <500 nanoseconds/record/core. Recursive subdivision of selection field ranges can guide searches that include those selection fields. One example includes geographic searching/filtering of records that include latitude and longitude fields.
