That purchase plunged Oracle deeper into Nashville's signature industry and almost assures that the company's planned $1.35 billion riverfront office campus on the East Bank will feature health care. Oracle has pledged to create 8,500 jobs by 2031, marking the largest jobs deal on record in city and state history.
