So because of this thread, I just went and perused the description of
the Clojure datalog library.
Some things I
Did you also read the overview that's part of contrib at
http://richhickey.github.com/clojure-contrib/doc/datalog.html.
I don't know if you already saw that, but since you didn't mention it,
I thought I'd be sure.

as an aside, i was under the impression that Datalog was syntactically
a subset of Prolog, but was not semantically so much so, since in
Prolog order matters e.g. wrt termination.

Thank you for being interested in the datalog library. :)

Thank you Josh for your answer.
I have read the sources of datalog, however, literal.clj and the ideas
of the query language behind it is unknown for me, thus I can not
understand it quite well. The same thing happens when I saw magic.clj,
in which file I saw "magic transformation".
I ran the ex

Two more questions:
3. In datalog.database , it is required that every tuple must has
exactly same field as in database define, is that possible to just
define some necessary fields, and tuples appended can have additional
optional fields?
4. What is a magic transformation? I googled the term, but
I am trying to use datalog now, have the following questions:
1. How about the memory consumption of datalog?
2. There are examples of datalog, but can I find more detailed
document about the query language?
