Data Warehousing

Data warehousing involves the process of collecting, storing, and managing data from varied sources into a single, consistent data store. It implements a systematic approach to organizing and structuring data for complex queries and analysis, using techniques like dimensional modeling, ETL processes, and OLAP (Online Analytical Processing). It includes concepts like dimensional modeling, data mart design, and optimization for analysis rather than transaction processing.
