  As new technologies move to the fore, our understanding of the world may seem
to have shrunk in comparison, for despite new developments in research, much of
it is reduced or rather, abstracted for marketability. Thus, the purpose of
this work is to provide a brief study of current techniques used in data
analysis that will yield some clarity and encourage new research. Several
applications of which are discussed in relation to the high data volume fields
e.g. health care and economics. Particular attention will be given to recent
developments in health care.
