Fifty years of relational.  It’s hard to believe the relational model has been around now for over half a century!  But it has—it was born on August 19th, 1969, when Codd’s first database paper was published.  And Chris Date was instrumental in making it all happen, working closely with Codd for many years and publishing the first, and highly influential, book on the subject in 1975.  In this unique presentation, Chris offers his own perspective on those fifty years.  No database professional can afford to miss this one of a kind history.


The presentation is in two parts, corresponding roughly to the first 25 years and the second 25 years, respectively.  Part I traces the development of relational technology from its early theoretical beginnings to its total dominance of the database marketplace (albeit in an unfortunately imperfect form) by the mid 1990s.  Part II explains how the industry then began to lose its way … It considers in some depth various claimed alternatives to the relational model, and explains why those alternatives are doomed to eventual failure.  It also shows how relational technology has led to success in a variety of important research areas, and it touches on issues where work still remains to be done.
