acknowledgments

Thanks go out to Jordan Tigani, cofounder and CEO of MotherDuck, who was our technical editor. His diligent work and feedback made our examples and writing a lot better. Big thanks also to all the other technical reviewers who diligently worked through the chapters and left their feedback, especially to Marcos Ortiz, Georg Heiler, and Jacob Matson for reviewing the original proposal, and to Dirk Gomez for checking all the code.

The writings and explanations by Mark Raasveldt, Hannes Mühleisen, and Alex Monahan helped us a lot, teaching us more about the inner workings of DuckDB, the ideas behind it, and some SQL gymnastics we had no idea were possible before. Thank you!

Many thanks to Ryan Boyd and Mehdi Ouazza. They not only gave valuable feedback but helped us a lot in making more people aware of the book.

We also thank the editing team at Manning, especially Rhonda Mason and Jonathan Gennick, for dealing so positively with us, and Christian Berk for his diligent copy editing and fast feedback loop. Michael Hunger and Michael Simons are happy about our colleagues at Neo4j, who may have raised an eyebrow or two but have enough self-confidence to acknowledge that both the graph and relational approach can coexist. DuckDB has been influential for us when thinking about empathy for users of our software.
