Data Warehouse

A centralized repository that stores historical and current hotel data from multiple operational systems in a structured format optimized for reporting and analysis. The data warehouse preserves historical snapshots that operational systems typically overwrite.

Why it matters: Without a data warehouse, historical performance data is lost as the PMS overwrites records. Year-over-year pace comparisons, trend analysis, and forecast models all depend on having clean historical data preserved in a data warehouse.
