Data Mining vs. Data Warehousing Key Differences and Applications

Abstract

Data mining and data warehousing are pivotal components in modern data management and analytics, supporting the extraction of meaningful information from large data sets to drive decision-making across industries. While data warehousing provides a structured environment for storing historical data from various sources, data mining involves the application of algorithms to discover patterns and relationships within that data. This paper discusses the fundamental differences between data mining and data warehousing, examining their respective architectures, processes, and applications. Data warehousing focuses on data storage, integration, and retrieval, whereas data mining emphasizes the extraction of actionable insights. Through this exploration, we analyze the complementary nature of these technologies, particularly in business intelligence (BI), healthcare, finance, and retail. Understanding these distinctions and synergies is essential for leveraging data mining and warehousing in complex, data-driven environments.
