Towards a Formalisation of Relational Database Theory in Constructive Type Theory
Paper i proceeding, 2004
We offer here an overview of several initial attempts of formalisation of relational database theory in a constructive, type-theoretic, framework. Each successive formalisation is of more generality, and correspondingly more complex, than the previous one. All our work is carried out in the proof editor Alfa for Martin-Löfrsquos monomorphic type theory. Our goal is to obtain a formalisation that provides us with computational content, instead of just being a completely abstract theory.
