Data mining involves what?

Data mining involves what?

• A. Companies analyse large amounts of data they hold about their customers
• B. It is the process of deleting customer data
• C. Data mining is illegal without consent
• D. Data mining is only for marketing

Answer: (A)

Data mining is about discovering patterns and useful insights by analyzing large data sets. In business, this usually means looking at the data a company already collects about customers—what they buy, how they browse, how they respond to offers—and using statistical and analytical methods to find trends, relationships, and predictions. That’s why describing it as companies analyzing large amounts of data they hold about their customers fits best. Deleting data is simply data management, not mining. Data mining isn’t inherently illegal without consent—legal and ethical rules govern use of data, but the technique itself isn’t defined by consent. And it isn’t limited to marketing; the same techniques are used for many purposes such as operations, security, and risk management.
