Abstract:

Abstract algebra has the power to unify seemingly disparate theories once they are encoded into the same abstract formalism. This paper shows how a relation-algebraic rendering of both database dependency theory and Hoare programming logic purports one such unification, in spite of the latter being an algorithmic theory and the former a data theory. The approach equips relational data with \emph{functional types} and an associated type system which is useful for database operation type checking and optimization. The prospect of a generic, unified approach to both programming and data theories on top of libraries already available in automated deduction systems is envisaged.
