We are interested in doing a comparison of logic programming systems with
database systems.

Has anyone compared a database-like program coded in a logic programming
language such as Prolog with the same program coded in a commercial database
system such as Ingres or Oracle?  Please give details of your comparison,
with the programs, machines, and systems you have compared, and the time and
space results of the comparison.  How difficult was it porting from one system
to the other?  How does the source program size compare?   And the memory
usage?

How difficult is it to interface Prolog with a database? What are the
trade-offs in deciding what parts of the problem are to be implemented in
Prolog and on the database system?

In what ways can logic languages or database systems be extended to incorporate
more of each other's abilities?  What are the implementation and performance
questions in doing such extensions?

Please send me e-mail giving any experience you have had in relation to any
of the issues touched by these questions.  If there is enough interest I will
post a summary to the net.

Thanks,
