Graph Transformation in Relational Databases
Electronic Notes in Theoretical Computer Science, 2005 AbstractWe present a novel approach to implement a graph transformation engine based on standard relational database management systems (RDBMSs). The essence of the approach is to create database views for each rules and to handle pattern matching by inner join operations while negative application conditions by left outer join operations. Furthermore,

Derivation of constraints and database relations
, 1996 In this paper we investigate which constraints may be derived from a given set of constraints. We show that, given a set of relations R, all of which are invariant under some set of permutations P, it is possible to derive any other relation which is invariant under P, using only the projection, Cartesian product, and selection operators, together with
