PARTwarehouse (focus on class systems) uses a different systematic structure than PARTsolutions (focus on the project, which represents a configurable component).
Leaf classes (classes without subclasses) match projects
Special case is a class which has both products and subclasses:
Klasse A - Klasse B - Produkt 1 - Produkt 2 - Produkt 3
Here, an artificial class is created during the export.
Klasse A - Klasse B - künstliche Klasse für Projekt - Produkt 1 - Produkt 2 - Produkt 3
Products match table rows (characteristics of the same part or different parts)
Attributes (class attributes) match table variables (in LinkDB or characteristic attribute table)
When importing or exporting the systems are mapped to each other.
