An Autonomous Data Warehouse is a cloud-based database that automatically manages and optimizes itself without human intervention. It uses advanced technologies like artificial intelligence and machine learning to handle tasks such as data loading, querying, and performance tuning, making it easier for businesses to analyze large amounts of data efficiently. This type of data warehouse is designed to be user-friendly, allowing users to focus on data analysis rather than database management. By automating routine tasks, it reduces the need for specialized IT skills, enabling organizations to gain insights from their data quickly and effectively.
