Presentation Transcript
Each product type is produced by exactly one factory. Over time, the factory that produces a given product type can change.
0..* FACTORY PRODUCT TYPE 1..1 from Product Type to Factory: The specifications say that a product type is produced by exactly one factory. Therefore, the minimum cardinality and the maximum cardinality are both one. from Factory to Product Type: The specifications do not mention the minimum or the maximum amount of product types a factory can produce. The default is then 0..* because this amounts to not putting any kind of constraint.
0..* FACTORY PRODUCT TYPE 1..1 Since a factory can produce many product types, FACTORY is not existence dependent on PRODUCT TYPE. !!! Since the factory that produces a given product type can change over time, PRODUCT TYPE is not existence dependent on FACTORY.
FACTORY PRODUCT TYPE ASSIGNMENT Each factory has zero to many existence dependent assignment objects, namely one per product type it produces. Each product type has exactly one existence dependent assignment object, namely for the factory that currently produces it. The association Factory-ProductType has been instantiated to the class ASSIGNMENT. Note: the case description is not completely clear about every cardinality.
