Data Warehouses

A data warehouse is a large, centralized repository designed to store and manage integrated data from multiple sources, optimized for querying and analysis. It organizes data into a structured format, typically using a schema-on-write approach, which involves transforming and cleaning data before it is loaded into the warehouse. This structured format makes it easier to perform complex queries and generate reports for business intelligence and decision-making. Data warehouses are essential for historical data analysis, trend identification, and supporting strategic business decisions by providing a comprehensive view of an organization’s data.
