Trebam prevesti "Barred relationship" pojam . Pronašao sam "objašnjenje" i manje-više mi je jasno što to jest ali kako taj pojam prevesti na "naš" jezik jer mi rešetka ili zatvor ne izgledaju logično iz objašnjenja?
"What they mean with the "barred relationships" is explained in the text. This is about the concrete representation of a Many-to-Many representation.
The original M:M relationship has become two 1:M relationships.
What would be the UID of the intersection entity?
Here comes the following section: Barred Relationships
The unique identifier (UID) of the intersection entity often comes from the originating relationships and is represented by the bars. In this case, the relationships from the originating entities to the intersection entity are called "barred" relationships.
This is because they make in the first place a pure modeling representation. To have a working implementation in a relation model (I guess Oracle Enterprise Database), there is a need to have a unique identifier in each entity and to introduce a new entity and relative relationships (barred relationships)."
Polako ide, ali učim :-)
