A look into the logic programming camp may be worthwhile, at least if
you are interested into extensions of the classical relational model, too.
A random link, just googled:
Constraint Programming and Database Query Languages
http://www.cs.brown.edu/publications/techreports/reports/CS-94-31.html
As far as I --accidentally-- know, there is some research going on
about the expressiveness of database query languages. (Think of a
database relating railway stations: x is railwise next to y, and query
it for a connection from Irkutsk to Perpignan, in SQL -- or relational
algebra, for that matter...)
