Welcome to The Third Manifesto (TTM), by Hugh Darwen and C.J. Date, our proposed foundation for future database systems presented in Databases, Types, and The Relational Model: The Third Manifesto, 3rd edition, Addison-Wesley, 2006 (ISBN: 0-321-39942-0). Minor revisions to the Manifesto given in Database Explorations (2010) are reproduced here.

The authors are grateful to the
Department of Computer Science, University of Warwick (UK)
for hosting this web site.

Thanks also to Lyle Hopkins, who redesigned the entire website in August, 2012.

Our aim in the third edition was to provide a text more suited to university courses, by reducing the polemics, enhancing the tutorial material, and adding exercises to each chapter. Solutions to the exercises are available to authorized instructors, in softcopy only, at the publisher's Instructor Resource Center. At this site we published additional material related to TTM, including a free PDF copy of that third edition and a relared book that came later, Database Explorations.
