Hotsos Symposium Keynote Speaker 2009

Chris DateWe are pleased to announce that this year's keynote speaker will be Chris Date. Mr. Date is one of the men who invented the relational model of database management.

Mr. Date will also speak at two of the sessions during the Symposium.

C. J. Date is an independent author, lecturer, researcher, and consultant, specializing in relational database technology (a field he helped pioneer). Prior to leaving IBM in 1983, he was involved in technical planning and externals design for the IBM products SQL/DS and DB2. His book An Introduction to Database Systems (8th edition published in 2004) is the standard text on the subject; it has sold well over three quarters of a million copies, not counting translations, and is used by several hundred colleges and universities worldwide. He is also the author of several other books on relational database management, including Databases, Types, and the Relational Model: The Third Manifesto (a collaboration with Hugh Darwen) as well as a proposal for the future direction of data and database systems. He has made a number of original contributions to database theory.


The topic for Mr. Date's keynote speech is entitled "Foundation Matters". This presentation is meant as a wake-up call. The foundation of the database field is, of course, the relational model. Sad to say, however, there are some in our field —certainly in industry, and to some extent in academia also — who don't seem to be as familiar with that model as they ought to be; there are others who seem to think it isn't very interesting or relevant to the day-to-day business of earning a living; and there are still others who seem to think all of the foundation level problems have been solved. Indeed, there seems to be a widespread feeling that "the world has moved on," so to speak, and the relational model as such is somehow passé.

In my opinion, nothing could be further from the truth! In this session (which is offered as a combined keynote and extended technical presentations), I want to sketch the results of some of my own investigations into database foundations over the past 25 years or so; my aim is to convey some of the excitement and abiding interest that is still to be found in those investigations, with a view — I hope — to inspiring others in the field to pay attention to such activities, and maybe to become involved.
