  Rezumat:   The basic idea of using Conceptual Graphs as query interface to relational databases has been stated by Sowa. The full expressiveness of modern database query languages includes negation and the so-called aggregating functions too. These features were introduced in [1] by means of Nested ConceptGraphs with Cuts. The novelty of the paper is the software named CGDBInter-face, which offers a graphical tool to query an existing relational database. The aim of our software tool is to connect to an existing database by giving the typeand the name of the database, a login name and password, then the software offers the structure of the database in form of a conceptual graph. The software provides a graph editor and a wizard to assist the user in constructing a query with Nested Concept Graphs with Cuts. To the best of our knowledge, such asoftware was not developed yet.
