DATA MINING
Traditional Database Query answer such as :
How many units of Product # 403 were shipped in March 2010?
OLAP supports much more complex requests for information such as ;
Compare Sales of Product 403 relative to Plan by Quarter and Sales Region
for the past two years.
With both OLAP and Query-oriented Analysis, Users need to have a good idea about the information for which they are looking for.
Data Mining however is more discovery driven:
–Data Mining provides insight into corporate data that can not be obtained with OLAP or traditional Database Query
–Data Mining finds hidden patterns and relationship in large Databases and Inferring Rules from them to predict future behaviour.
The Patterns and Inferring Rules are used to guide Decision making and forecast the effect of those decisions.
