Explanation

A data warehouse architecture consists of three core components: metadata (technical and business definitions about the data), summary data (aggregated facts and metrics pre-calculated for query performance), and raw data (detailed transaction records from source systems). Metadata includes schemas, transformation rules, and data lineage; summary data contains pre-aggregated metrics like monthly sales totals; raw data holds the granular source records that enable drill-down analysis.
