The invention proposes interacting with a database having data related to modeled products and parts using a graphical user interface displayed by a computer. The graphical user interface is adapted to allow a user to access the database. The method also includes providing within the graphical user interface a toolbar with at least one field suitable for displaying an argument. The toolbar is adapted for allowing a user to execute a function using the argument. The method further includes the steps of querying the database and updating the argument displayed in the field using a result of the querying step.
