Which of the following best defines data mining?
- A.Taking a backup of all company files
- B.Discovering patterns and relationships in large volumes of data
- C.Deleting duplicate rows from a table
- D.Encrypting records before sending them
Correct answer
Explanation
The correct answer is B. Data mining applies statistical and machine learning techniques to large stores of data to find knowledge that was not asked for in advance: customer segments, associations between products bought together, trends over time and unusual cases that may be fraud. Option A is wrong because taking a backup is a copy made for safety and recovery, with no analysis involved. Option C is wrong because removing duplicate rows is part of data cleaning, one preparatory step before mining rather than mining itself. Option D is wrong because encryption protects data in storage or transit and is a security measure. Keep three related terms apart: a data warehouse is the store of historical data, OLAP is the processing style used to query it, and data mining is the search for patterns within it.
