Also know, what is the difference between KDD and data mining?

KDD is the overall process of extracting knowledge from data while Data Mining is a step inside the KDD process, which deals with identifying patterns in data.

Similarly, what is data mining and its types? Important Data mining techniques are Classification, clustering, Regression, Association rules, Outer detection, Sequential Patterns, and prediction. R-language and Oracle Data mining are prominent data mining tools. Data mining technique helps companies to get knowledge-based information.

Accordingly, what is meant by KDD?

The term Knowledge Discovery in Databases, or KDD for short, refers to the broad process of finding knowledge in data, and emphasizes the "high-level" application of particular data mining methods. The unifying goal of the KDD process is to extract knowledge from data in the context of large databases.
