Bounded Fixpoints for Complex Objectscoding of . with unbounded fixpoints into flat relations. We also define a complex object logic based language with fixpoints and prove that its range restricted fragment is equivalent to . with bounded fixpoints.

The Triumph of the Rational Subjectare not the most technically superior, and SQL became the dominant language in the relational database world, despite many clearly better ideas: Quel and E-Quel from Ingres, the Relational Model book produced by Michael Brodie et al, and so forth. Now SQL is the standard database interface even if your database is not relational!

Matti Kamppinen,Antti Revonsuo,Seppo Sajamaon. We also show how to generate efficient algorithms for checking a large class of constraints. We show how all the techniques presented took great advantage of the underlying type system which provide a significant help both in solving (1) and (2). Last the current status of the Thémis prototype is presented.

A Functional Object Database LanguageL and these functional languages have w.r.t. each other in terms of (i) the above-mentioned flexibility in the type system, which we consider essential for . and (ii) the orthogonality of the language.
