Data Mining
Data Mining is a way of finding useful patterns and insights in large sets of information. Think of it like looking for treasure in a mountain of data. Professionals who do data mining help companies make better decisions by uncovering hidden trends in their customer information, sales figures, or other business data. They use special computer programs and statistical methods to sort through this information, similar to how a detective looks for clues. This is part of a broader field called "data analytics" or "business intelligence." Other related terms you might see include "predictive analytics" or "statistical analysis."
