A data warehouse is a system that stores extensive company data, serving as a single truth source for business intelligence tasks, machine learning modeling, and more.

A data warehouse integrates with various data-generating tools to ingest large volumes of data. This integration is achieved through native connectors or ETL processes.

There are three common data transformations within a data warehouse:

• Integration – Serves as an endpoint for data from diverse sources like APIs and databases.

• Cleaning – Data from different sources is cleaned before consolidation for reliable data.

• Consolidation – Combines and distills clean data from various sources to extract valuable information.
