Management of Flexible Schema Data in RDBMSs - Opportunities and Limitations for NoSQL

Summary: Advocates managing Flexible Schema Data (FSD)—data‑first semi/unstructured, rapidly evolving records—inside RDBMSs rather than large optional schemas or wholesale NoSQL migration. Outlines engineering practices, limitations, and research opportunities to unify structured and FSD workloads. (summarized by gpt-5-mini on Feb 09 2026)
