Dear Torsten, good grief no, I did not mean that the topic / field was obsolete. In fact most of my posts over the last couple of months are inquiries on this very subject. (Apart from the occasional glitch). Well about EDSL for Relational Algebra. I was very excited when I found your paper and noticed your other works. My question was more, and please don't get this the wrong way, if your findings from over 10 years ago may have been superseded my more recent discoveries or techniques. It will take me a very long time to absorb your paper, in fact I might not even be able to understand it all, but I'll try. But before I do so I wanted to make sure that it's still the "state of the art". Best regards Günther Am 28.03.10 21:58, schrieb Torsten Grust:
Günther,
feel free to contact me when it comes to questions regarding ``Comprehending Queries.''
Understanding database queries as (specific) functional programs is far from being an obsolete endeavor. Quite the contrary. Think LINQ (Microsoft) or Links (Philip Wadler). Or Kleisli (Limsoon Wong). Or monoid comprehensions (Leo Fegaras). Or Ferry (my group at U Tübingen) [1].
Cheers, --Torsten (no `h' in here ;-)

Hi all,
is anyone here familiar with the paper "Comprehending Queries" by Thorsten Grust? http://kops.ub.uni-konstanz.de/volltexte/1999/312/pdf/312_1.pdf
As the paper dates from 1999 I wonder if its content may have been "obsoleted" by later works or if it still is pretty much current.
I ask this because I'm still struggling to put my program with lots of queries on a more sound code base.
Günther
