An Autonomous Database is a type of database that uses artificial intelligence (AI) to manage itself. It automates tasks such as tuning, patching, and scaling, which traditionally required manual intervention by database administrators. This technology helps improve performance and reduce operational costs, making it easier for organizations to handle large amounts of data. By leveraging machine learning, an Autonomous Database can adapt to changing workloads and optimize its resources in real-time. This means it can efficiently allocate storage and processing power based on demand, ensuring that applications run smoothly without human oversight.
