A data warehouse is a centralized repository that integrates data from multiple sources into a consistent, cleansed and standardized schema optimized for analytics and reporting. It serves as a single source of truth for enterprise data.
Data warehouses transform raw data into structured formats using ETL processes to enable business intelligence and analytics. They are a core component of modern data lakes and data orchestration pipelines.
A data warehouse consolidates data from transactional systems, databases, IoT devices, social media and other sources into a unified schema. It applies data cleansing, transformations, aggregations and business logic to present integrated views of business data.
Analytical tools and dashboards can then run high-performance queries against the integrated data in the warehouse to drive business insights, forecasts and decision making.
Data warehouses enable using data for strategic business intelligence as opposed to just transactional operations. They provide the trusted information backbone for analytics across sales, marketing, finance, supply chain and more.
With a single integrated view of enterprise data, data warehouses deliver the reporting, segmentation, forecasting and predictive models essential for data-driven management and optimization of business processes.
A data warehouse is a centralized repository that integrates data from multiple sources to support analytics and reporting. The key components provide capabilities for data integration, storage, management, and access.
Data warehouses enable consolidated data and are well-suited for certain use cases needing integrated data at scale for analytics.
Data warehouses come with inherent complexities around scale, operations, and governance:
A data lake is a scalable data repository that stores vast amounts of raw data in its native formats until needed.
