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, the model manipulation prescribed by the application of a graph transformation rule is also implemented using elementary data manipulation statements (such as insert, delete, update).}, keywords = {graph transformation, Pattern matching, relational databases, Tool support}, url = {http://www.inf.mit.bme.hu/FTSRG/Publications/varro/2004/grabats2004_vfv.pdf}, author = {Gergely Varr{\'o} and Katalin Friedl and D{\'a}niel Varr{\'o}} }
