Getting an overview of the structure within the database is essential to understand, how the data can be retrieved. Adding GF/ST and its visualisation services to PUM is therefore a first step:
The diagram shows some classes (but only their available associations to other classes) at the “top” of the persistent hierarchy … so some kind of association viewer.
In this version I added a global association viewer (searching for the startup class by itself) or a viewer, where the user selects a starting class.
