We 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,
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). ? 2005 Elsevier B.V. All rights reserved.
