Data Mining
Data Mining is a way of finding useful patterns and insights in large sets of information. Think of it like being a detective who looks through massive amounts of data to find valuable clues and trends. Companies use data mining to make better business decisions, understand customer behavior, and predict future trends. It's similar to data analysis or business intelligence, but focuses more on discovering hidden patterns automatically. When you see this term in a resume, it usually means the person knows how to use special tools and techniques to uncover meaningful information from large databases.
