Free industry demo database samples
Mini Samples are intentionally small excerpts of DemoDataWorks' realistic industry demo data — enough to inspect data quality and relational structure before buying, practice SQL, run basic analytics, or put together a simple demonstration. No signup, no account, no checkout — just a direct download.

Two Mini Samples, ready now.
Deterministic, realistic, and relationally complete — every included ID resolves within the sample.
