Oracle Autonomous Data Warehouse

Oracle's self-tuning, self-patching cloud data warehouse built on Oracle Database with elastic OCPU and storage scaling.

Visit Oracle Autonomous Data Warehouse Alternatives

Oracle Autonomous Data Warehouse is a fully managed cloud data warehouse built on Oracle Database, positioned around automation: Oracle handles tuning, patching, backups, and scaling with minimal administrator intervention, using machine learning internally to manage indexes and workload distribution. It scales compute (OCPUs) and storage independently and elastically, and inherits Oracle Database's SQL surface, PL/SQL support, and in-database machine learning and graph analytics features. It runs on Oracle Cloud Infrastructure (OCI), including OCI's Always Free tier for small workloads, and Exadata-based hardware for high-performance configurations. ADW is a natural fit for organizations already running Oracle Database workloads that want to move analytical processing to a managed, autoscaling cloud service without re-platforming off Oracle SQL.

Terms to know

Data warehouse A centralized, structured database optimized for fast historical reporting rather than day-to-day transactions. Machine learning Building models that learn patterns from data to make predictions or decisions, rather than following hand-coded rules. OLAP (online analytical processing) A category of technology optimized for fast, multi-dimensional aggregation and slicing of data for analysis. Graph analytics Analyzing data modeled as nodes and edges to study connections, structure, and influence rather than isolated records.
