  "description": "A data warehouse is a centralized repository optimized for analytical queries (OLAP) rather than transactional operations (OLTP). Kimball methodology: star schema (fact tables + dimension tables). ETL (Extract-Transform-Load) pipelines populate the warehouse from operational systems.
