Relations between uml diagrams

Question

I have something like this

public class Item
{
   public string FirstName { get; set; }
   public string LastName { get; set; }
   public int ID { get; set; }
}

public class Data
{
    public List<Item> Items { get; set; }
}

what is right type of relationsheeps between them? Dependency?

You are right - Data is dependent on Item, since it "owns" many Items. This is a form of aggregation.

This is the arrow you are searching for:

         0..*     0..*
| Data | ＜＞―――――――＞ | Item |

I added a picture. The multiplicity is not deducible from the code. So I left it away. – qwerty_so Dec 03 '15 at 17:45

I don't know what your model means, but here is a version of it in normal UML 2:

If I were you, I would put a property on both ends of the association and give each one a semantically strong name. For example, describedItems and describingData. Please see how to indicate a list of types in UML and this answer on association ends.
