Data mining is a process that uses a variety of data analysis tools to
discover patterns and relationships in data that may be used to make
valid predictions. To mine the hidden and useful information we have to
take the available dataset through the process of data mining. It's not
a single step. It contains various groups of interlinking steps which
will help us to find the useful information for decision making. Data
mining searches databases to find hidden patterns and predict
information to increase the business in the organization.Data mining is
the nontrivial extraction of implicit, previously unknown, interesting
and potentially useful information from data . Now a day's hospitals and
health care institutions are well equipped with monitoring and other
data collection devices, where data is collected and shared with other
hospital information systems.
