Answer to Question 1

B

Answer to Question 2

A crucial process for consolidating data from operational systems with other organizational data-to facilitate the use of data mining techniques to gain the greatest and broadest understanding from the data-is extraction, transformation, and loading.

First, the data need to be extracted from different systems. In the transformation stage, data are being cleansed and manipulated to fit the needs of the analysis. Data cleansing refers to the process of detecting, correcting (e.g., standardizing the format), or removing corrupt or inaccurate data retrieved from different systems. Finally, the transformed data are loaded into the data warehouse and are ready for being used for complex analyses.
