    Lightbulb Implementing Supertypes-Subtypes with relations

    I have read numerous texts/articles about ER modelling that involves supertype-subtype structures but none are clear in the way that these structures can be implemented in a relational database.

    Some suggest it can be done, some suggest it can't but none of them give proof or examples.

    Can anybody shed a bit of light on the subject?
