The main idea is that data mining algorithms are used to uncover patterns, relationships, and models that aren’t obvious to people when looking at large amounts of data. By applying statistical methods, machine learning, and pattern discovery techniques to databases, they reveal insights such as frequent co-occurrences, associations, clusters, or predictive rules. This extracted knowledge can inform decisions, guide interventions, and support improvements in patient care and operations. For example, algorithms might reveal a combination of factors that predicts higher risk for a complication, information that isn’t apparent from reviewing individual records alone. Other activities like simply sorting names, storing data in a data warehouse, or generating billing codes are routine data management tasks and do not constitute discovering new insights from the data.
