Oracle（ORCL）深度研究：數據庫護城河 × OCI AI 基礎設施爆發 Oracle 是全球最被低估的 AI 基礎設施卡位者。DB 護城河轉換成本最深（5/5）、OCI +84% YoY、RPO $4,550 億確認需求不虛。後進者另辟戰場：主權雲 + 醫療 AI（Cerner EHR）+ 政府國防。客戶變競爭者是第二階段風險。PVL：✅ 可深入研究。
Oracle (ORCL) Deep Research: Database Moat × OCI AI Infrastructure Surge Oracle: deepest DB switching-cost moat + OCI +84% YoY, $455B RPO (6× revenue). Late entrant, different battlefield. Healthcare AI via Cerner EHR, sovereign cloud, defense compute = untapped moats. Self-build clients as future competitors: unpriced risk. 43% Non-GAAP margin. PVL: Research-worthy.
