What is Data Warehouse?

A data warehouse is a central repository of large amounts of data that originates from various sources, both internal and external to an organization. It is specifically designed to support business intelligence activities, such as reporting, analysis, and decision-making.

Data warehouses are structured databases that store and organize data in a way that facilitates efficient querying and analysis. They integrate data from multiple sources and typically store historical data, allowing users to analyze trends and patterns over time. Additionally, data warehouses often contain data that has been transformed and cleansed to ensure consistency and accuracy.

The primary purpose of a data warehouse is to provide a unified view of an organization's data, making it easier for users to access and analyze information. This centralized approach enhances data consistency and eliminates the need to access multiple systems or databases for reporting and analysis purposes.

In a data warehouse, data is organized into a dimensional model, which consists of one or more fact tables and related dimension tables. Fact tables contain numerical values, known as metrics or measures, representing the different aspects of the business being analyzed. Dimension tables provide context for the measures by describing the characteristics or attributes associated with them.

To facilitate efficient querying and analysis, data warehouses often employ techniques such as indexing, partitioning, and aggregations. These techniques optimize performance by reducing data retrieval times and improving query response.
