Quick Summary

A data warehouse is a system used for reporting and data analysis, considered a core component of business intelligence. It is a type of data management system that aggregates and organizes data from one or more different sources. Data warehouses store current and historical data in one single place that are used for creating analytical reports for workers throughout the enterprise. The process of moving data from its original sources to a centralized location is called ETL (extract, transform, and load). This allows for the analysis of vast amounts of data that would otherwise be too large to process.12
