It transforms raw data into a structured format that is easy to analyze, providing a unified view of the organization's operations and performance.

The main role of a data warehouse is to consolidate and harmonize data from various sources into a consistent format. It involves extracting data, transforming it into a suitable structure, and loading it into the warehouse. This process is often called ETL (Extract, Transform, Load). By structuring the data in a uniform way, a data warehouse enables users to perform complex queries and generate meaningful reports without hindrance.

Data warehouses also provide historical data, storing information over a long period of time. This historical perspective allows analysts to track the organization's performance trends and identify patterns or anomalies. It enhances decision-making by providing a broader context and facilitating predictions or forecasting. Without a data warehouse, organizations would struggle to efficiently store, integrate, and analyze large volumes of data, limiting their ability to gain valuable insights and make data-driven decisions.
