This document discusses data warehousing and mining. It explains that data warehousing is the process of consolidating data from multiple sources into a centralized location. Data mining is the process of analyzing this data to find patterns and relationships. It describes typical analysis tasks, challenges in data warehousing, OLAP for interactive queries, and basic data mining techniques like classification, clustering, and association rule mining.
