The question mark combined with the Default Mapped
text in the brackets is used for the unambiguous distinction between the tables that are explicitly mapped to a class and the tables that are default mapped (when you use Default Mapping
, OpenAccess ORM takes care for the update of the table's columns according to the changes in the class).
Regarding the greyed icons, OpenAccess ORM has two types of those: the first one is the same as the icon of an explicitly mapped table and means that currently the table is present in the model but there is no domain class generated for it; and the second one is used to mark the join table in a many-to-many association between explicitly mapped tables.
