A data warehouse is an evolving resource that supports key business processes for reporting, business intelligence, and more. Here are the common characteristics of a data warehouse:
- 1
Subject oriented People can access data via topics tied to business units and processes that they work with daily.
- 2
Consistent data Data formats and values are standardized, complete, and accurate. Data must have integrity.
- 3
Updated in real time Changes are tracked over time to create an effective corporate memory of the enterprise.

What's the difference between a data warehouse and an enterprise data warehouse (EDW)?
What's the difference between a data warehouse and an enterprise data warehouse (EDW)?
A data warehouse is a centralized repository that consolidates data from multiple operational sources and is optimized for analytics, reporting, and business intelligence.
An enterprise data warehouse (EDW) extends this concept to serve the entire organization: It aggregates data from across all business units, integrates multiple systems, and supports enterprise-wide analytics and decision-making.
In short: All EDWs are data warehouses, but not all data warehouses reach the scale, scope, or integration level of an EDW.
What types of data are stored in an EDW?
What types of data are stored in an EDW?
An EDW typically stores:
- Structured data, such as transactional records, customer and product tables, finance data, and CRM/ERP data, which are integrated and subject oriented
- Time-variant/historical data, meaning the EDW retains data across time periods to support trend analysis and forecasting
- Integrated data from multiple sources, meaning data from different business applications that has been cleaned, reconciled, and standardized
- EDWs primarily ingest structured data, but modern EDWs may also ingest semi-structured and contextualized data (like logs, XML/JSON, and enriched external feeds) when transformed for analytics
An EDW provides a consolidated, cleansed, and optimized dataset that supports enterprise analytics, reporting, and decision-making
What are the key characteristics of a high-performing EDW?
What are the key characteristics of a high-performing EDW?
Key attributes include subject orientation (organized by business themes), integration (standardized naming and formats), time variance (historical context), non-volatility (data is stable once loaded), scalability, governance, and performance for analytics
