Key Updates: Vector Database Capabilities:Vector indexing for unstructured data (text, audio), can be queried jointly with transactional data (limited preview) Private Agent Factory:No-code AI Agent builder, with built-in knowledge base Agent and data analysis Agent Unified Memory Core:Low-latency inference engine, unifying vector/JSON/graph/relational data storage Deep Data Security:Row/column + Agent level data access control DBA Perspective Previously, AI applications required a separate vector database + ETL pipeline. Now Oracle sinks AI capabilities into the kernel, DBAs only need to manage one database to support transactions + analytics + RAG. The Private Agent Factory deserves special attention — DBAs need to relearn “database + Agent” permission models to prevent Agents from accessing sensitive data beyond their authority. Impact on Teams:If upgrading to 23ai, start with a “knowledge base Agent” pilot to evaluate the real cost of vector indexing on storage […]
