1. Two Decades of Engineered Systems Milestones
When Larry Ellison announced the Sun Oracle Exadata V2 in 2009, it introduced the concept of an engineered database appliance with PCI flash cards and Smart Scan software. Over eleven generations, Exadata transitioned from a niche data warehouse accelerator into the foundational platform for tier-1 global banking, telecom, and ERP workloads.
