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.
norm noun [C]. âº an âaccepted âstandard or a way of being or doing things: Illness has âbecome the norm for her. (Definition of norm from the Cambridge Academic Content Dictionary Â© Cambridge University Press). See all translations.
Equivalent norms define the same notions of continuity and convergence and for many purposes do not need to be distinguished. To be more precise the uniform structure defined by equivalent norms on the vector space is uniformly isomorphic. Every (semi)-norm is a sublinear function, which implies that every norm is a convex function.
