Two-level graph grammars, grammars, the former resulting from the lack of parameters, the latter from the general lack of structure of string manipulation systems. As a field of application of 2GG‘s, the formal description of programming languages is focussed.

Graph grammars and operational semantics,ion rules carries over to the correctness of derivations via such rules. Applying this result to LISP we show that a LISP interpreter represented by a graph grammar is correct with respect to the functional semantics of graphlike LISP expressions.

Transformations of data base structures,nsform one configuration into another one. Valid configurations are those that conform to the integrity constraints declared for the particular data base..In this work we investigate the use of graph grammars for the specification of data base operations, in ways that preserve the imposed integrity constraints.
