Oracle Data Lakehouse streamlines the integration, storage, and processing of data.

In Oracle’s Data Lakehouse architecture, data persistence refers to the storage layer where data is durably maintained. "Autonomous Database" (B) provides a managed, self-tuning relational database for structured data persistence, supporting SQL-based workloads. "OCI Object Storage" (D) offers scalable, durable storage for unstructured and semi-structured data, such as files, images, and logs, serving as the data lake component of the Lakehouse. "OCI Data Catalog" (A) is a metadata management service, not a persistence layer, and "OCI GoldenGate" (C) handles data replication and integration, not direct storage. Oracle’s Lakehouse documentation identifies Autonomous Database and OCI Object Storage as the primary persistence services.
