Abstract
Data mining is a process which finds useful patterns from large amount of data. The paper discusses
few of the data mining
techniques, algorithms and some of the organizations which have adapted data mining technology to improve their businesses and
found excellent results.
Keywords: Data mining Techniques; Data
mining algorithms; Data mining applications.
1. Overview of Data Mining
The development of Information Technology has generated large amount of databases and huge data in
various areas. The research in databases and information technology has given rise
to an approach to store
and manipulate this precious data for further decision making. Data mining is a process of extraction of
useful information and patterns from huge data. It is also called
as knowledge discovery process,
knowledge mining from data, knowledge extraction or data /pattern analysis.
Figure 1. Knowledge
discovery Process
Data mining is a logical process that is used to search through large amount of data in order to find
useful data. The goal of this technique is to find patterns that were previously unknown. Once these
patterns are found they can further be used to make certain decisions for development of their businesses.
Three
steps involved are
Exploration
Pattern identification
Deployment
Exploration: In the first step of data exploration data is cleaned and transformed into another form, and
important variables and then nature of data based on the problem are determined.

Pattern Identification: Once
data is explored, refined and defined for the specific variables the second step
is to form pattern identification. Identify and choose the patterns which make the best prediction.
Deployment: Patterns are deployed for desired outcome.
