Question 1

Explain the characteristics and advantages of data mining systems.

Accepted Answer

Data mining systems process data using sophisticated statistical techniques,such as regression analysis and decision tree analysis.Data mining systems find patterns and relationships that cannot be found by simpler reporting operations,such as sorting,grouping,and averaging.Data mining systems improve decision making by using the discovered patterns and relationships to anticipate events or to predict future outcomes.
