Oracle Autonomous Database

Oracle Autonomous Database pioneered self-driving database capabilities with automated patching, tuning, indexing, backups, and failover without DBA intervention. Available as Autonomous Data Warehouse (ADW) for analytics or Autonomous Transaction Processing (ATP) for OLTP. Pricing uses ECPU model with serverless (pay-per-use), dedicated (predictable pricing), and Exadata Cloud@Customer deployment options. Free tier available on Oracle Cloud (20GB storage, 1 ECPU). Self-driving capabilities include automatic indexing (ML-driven index recommendations and creation), automatic SQL plan management, automatic statistics gathering, and automatic workload scaling. Select AI enables natural language to SQL using OCI Generative AI service with integration to GPT-4, Cohere, and Oracle-hosted models. The database automatically generates execution plans, caches queries, and manages memory without manual tuning. Autonomous Database on Dedicated Exadata provides isolated infrastructure for highest security requirements.
