HBase is a sparse, distributed, persistent multidimensional sorted map. The map is indexed by a row key, column key, and a timestamp; each value in the map is an uninterpreted array of bytes. Applications store rows in labelled tables. A row has a sortable key and an arbitrary number of columns. All rows are sorted in strict alphabetical sequence.

Norms are the bridge between principles and rules. Norms are different from rules in that rules state exactly what must occur, when and how. Principles are more general in that they guide people but never provide the 'how' to do it.
