Analysis of Data Mining Techniques and Applications

Abstract

With the exponential growth of digital data in recent years, data mining has become an essential process for extracting meaningful patterns, trends, and knowledge from large datasets. This paper presents an analytical study of various data mining techniques and their applications across multiple domains. Key methods such as classification, clustering, regression, association rule mining, and anomaly detection are examined for their effectiveness and practical implementation. The study highlights how these techniques are applied in diverse fields including healthcare, finance, education, marketing, and cybersecurity to support data-driven decision-making. Furthermore, the paper discusses challenges such as data quality, scalability, privacy, and model interpretability that affect mining performance. Comparative analysis reveals that hybrid and ensemble-based approaches often enhance accuracy and efficiency in complex datasets. Overall, this study emphasizes the growing significance of data mining as a core component of modern analytics and its role in transforming raw data into valuable insights for intelligent decision support systems.
