AiVibeData Warehouse
A data warehouse is a central, structured repository that integrates cleaned data from multiple business and operational systems, modelled for fast analytical SQL queries, reporting and business intelligence.
A data warehouse is a central repository that integrates cleaned, structured data from multiple operational systems to support reporting, business intelligence and analysis. Data is modelled before loading, often into dimensional star schemas with fact and dimension tables, an approach associated with Ralph Kimball, and is organised by subject rather than by source application. Warehouses typically use columnar storage and massively parallel processing to run analytical SQL queries over large historical datasets.
Enterprises use warehouses for financial reporting, sales and supply chain analytics, and in manufacturing for production, quality, OEE and cost reporting that combines MES, ERP and maintenance data. Cloud data warehouses such as Amazon Redshift, Google BigQuery, Snowflake and Azure Synapse Analytics separate storage from compute so that each can scale independently, and many are billed by query volume or compute time.
Warehouses apply schema on write, which gives consistent, trusted data but makes adding new sources slower than in a data lake. Data must be refreshed through ETL or ELT pipelines, so freshness depends on load schedules unless streaming ingestion is used. Cost control requires attention to query patterns, clustering or partitioning and idle compute, and access to sensitive data should be restricted by role.
Key points
- Stores cleaned, structured data modelled for analysis, often as star schemas
- Applies schema on write, giving consistent and trusted reporting data
- Cloud warehouses include Amazon Redshift, Google BigQuery, Snowflake and Azure Synapse
- Loaded by ETL or ELT pipelines, so freshness depends on load frequency
