A Comparison of Flexible Schemas for Software as a Service
Summary: Five flexible SaaS schemas for multi-tenant DBs evaluated: DB-owned vs app-owned (XML in DB2, Pivot Tables in HBase). DB-owned yields fast runtimes but limited online evolution; app-owned enables schema agility at a performance cost; no ideal SaaS DB yet. (summarized by gpt-5-nano on Feb 09 2026)
