I am trying to figure out how to set the attributes of the attributes such as foreign-key, primary-key,auto-increment. How do you set them in the app?
The best way is to choose Entity Relationship Diagram (Project/Add Diagram/Other/Entity Relationship Diagram). Insert an entity to your diagram, add an attribute, right-click on it and choose Primary Key, Foreign Key, Nullable or Auto Increment from context menu.
If you want to use UML Class Diagram, you can add an attribute with custom stereotypes to a class. You can create custom stereotypes for foreign key and auto increment (right click on attribute / Field Properties / Stereotypes tab). You can use (UML) standard modifier 'ID' for primary key (right click on attribute / Field Properties / Modifiers group)
I can't select the association multiplicity in the Class diagrams, it opens and closes very fast in the upper left corner. It looks like a bug. Can somebody help me?
This problem may occur at some zoom levels. It will be fixed in the next release this week.
