This paper compares a “row major order” data structure that is used standard relational databases against the transposed “column major order” data structure used by CARE. These data structures are described in detail, as were the various filtering methods that could be employed. Performance tradeoffs between the two data structures demonstrated a clear advantage of the column major order over the traditional storage approaches.
