“Data Mining is a non-trivial extraction of implicit, previously
unknown and potential useful information about data”[1]. In
short, it is a process of analyzing data from different
perspective and gathering the knowledge from it. The
discovered knowledge can be used for different applications
for example healthcare industry. Nowadays healthcare
industry generates large amount of data about patients, disease
diagnosis etc. Data mining provides a set of techniques to
discover hidden patterns from data. A major challenge facing
Healthcare industry is quality of service. Quality of service
implies diagnosing disease correctly & provides effective
treatments to patients. Poor diagnosis can lead to disastrous
consequences which are unacceptable.
