Loose coupling No coupling Question 9 options: True False interval-scaled attribute is a numeric attribute with an inherent zero-point. Tight Coupling Which of the following is not part of data warehouse technologies? Question 14 options: Data Cleaning Question 10 options: True False A high standard deviation means that the data observations tend to be very close to the mean, while a low standard deviation indicates that the data are spread out over a large range of values. Data Integration Online Analytical Processing Supply Chain Management Question 11 options: True False Predictive mining tasks perform induction on the current data in order to make prediction. In the database or data warehouse system is fully integrated as part of the data mining system and thereby provides optimized data mining query processing. Thus, the data mining subsystem is treated as one functional component of an information system.
