Hello, I saw oracle will release AI-driven oracle database (database with machine-learning). Questions: 1. When Oracle will release this version database? 2. What is this version database called? (for example, current database is called 12c) 3. How does the pricing model work? 4. How much it would cost? 5. What is their new release cycle for these products? 6. How would upgrade work? 7. Does it totally self-tuned? (remove db tuning work like traditional DBA did). 8. Anywhere we can find demo video? Thank you!
