  In this paper we have focused a variety of techniques, approaches and
different areas of the research which are helpful and marked as the important
field of data mining Technologies. As we are aware that many Multinational
companies and large organizations are operated in different places of the
different countries.Each place of operation may generate large volumes of data.
Corporate decision makers require access from all such sources and take

engineering.To analyze,manage and make a decision of such type of huge amount
of data we need techniques called the data mining which will transforming in
many fields.This paper imparts more number of applications of the data mining
and also focuses scope of the data mining which will helpful in the further
research.
