Reply To: Where to put the referential attributes?

[Lee Riemenschneider]

Sorry. Let’s do this again, in UML.

All rules are reflexive. e.g., 0..1:1 follows the same rule as 1:0..1

1:1 – choose either side
1:0..1 – 0..1
1:1..* – 1..*
1:* – *
0..1:0..1 – use associative object
0..1:1..* – use associative object
0..1:* – use associative object
1..*:1..* – use associative object
*:1..* – use associative object
*:* – use associative object
