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.

Convention (norm) A convention is a set of agreed, stipulated, or generally accepted standards, norms, social norms, or criteria, often taking the form of a custom. Certain types of rules or customs may become law and regulatory legislation may be introduced to formalize or enforce the convention (for example, laws that define on which side of the road vehicles must be driven).
