UML Domain Model
I'm trying to get into Java oriented programming,
and have seen this characterisation a few times.
Specifically the *; I know that the 1..* means that a Section belongs to Infinite number of articles but at least 1. but what does * by itself mean 0..* ?, 1..* ?
I know this might seem like a minor grammar thing, but I haven't come across this specific way in any text books. I'm just trying to understand what is meant by it.
Solution
- 1 means 1 and only 1
- 1..* means >= 1
- 0..* means >= 0
- a single star means >= 0 means 0..*
Note : Some UML tools use N instead of star
