Question

Mara Kay is a system analyst for a national department store. She was tasked to identify previously unknown relationships in the company's sales data that can be used in future promotions. What technique would Mara most likely use?

Answer 1

Answer: Data Mining

Explanation: Mara Kay tasked with identifying previously unknown relationships in the company's sales data. This is an indication that Mara Kay will be working with pre-existing company data.  

Data Mining can therefore be defined as the examination of large pre-existing databases in order to discover/identify patterns that will be useful in generating new information.

Data Mining is also known as Knowledge Discovery in Databases.

Data Mining will not be complete if the results of the analysis are not used for future purposes, therefore, Mara Kay will use the results of her findings for future promotions.
