We focus on EJB-database interactions as a concrete context for our work, but our results are applicable to other programming language-database interactions.

Containment of Relational Queries with Annotation Propagationharacterization suggests that annotation-containment is more complex than query containment, we show that the annotation-containment problem is NP-complete, thus putting it in the same complexity class as query containment. In addition, we show that the annotation placement problem, which was first

While full XPath is P-complete w.r.t. combined complexity, various (minor) restrictions are known which reduce the complexity to highly parallelizable complexity classes [2]. Finally

An Epistemology for Phenomenology? is based on the PVS theorem prover technology, and it combines static and dynamic checking to attain reasonable performance. The theorem prover technology is itself based on a sophisticated type system equipped with a form of semantic subtyping and parametric polymorphism. The higher-order features
