The Properties of DB Category,It is demonstrated that . is a V-category enriched over itself..Finally, we present the inductive principle for objects and the coinductive principle for arrows in the . category, and demonstrate that its “computation” Kleisly category is embedded into the database . category by a faithful forgetful functor.

It is important also due to the fact that usually the database experts do a lot with logics and relational algebras, but much less with programming languages (their denotational and operational semantics) and still much less with categorial seman

The objects of this category are the instance-databases (composed of the relational tables and an empty relation ⊥) and every arrow is just a set of functions (mapping-interpretations defined in Chap.?.) from the set of relations of the source object (a source database) into a particular rel
