Title: Linking to Virtualised End Points
Post by: Screwtape on July 12, 2016, 08:50:03 pm

Hi Folks!

I'm trying to draw a class diagram that represents the data required in a query. I thought using virtualised end-points would help show the structure, but it doesn't.

I'm looking to do something like:

A--B--C--B--B--D

So I virtualised the B following C, but I cannot link anything to the virtualised end.

Is there any way to link to the virtualised end-point, or can anyone suggest a better way of representing a table multiply linked in a query structure.

Thanks for your help.

Draw as many associations as needed. B connects to A, C (twice), D and self. A to B, C twice to B, and D to B. You could name the association in the order you need them.

As you do that for a query, you will probably use instances. In that case just use multiple instances and you're also done.

Virtualised End Points aren't real - that's why they are virtualised.   ;)

You get one per real relation (and only when the line type is correct - see my (fairly) recent posts on virtualised End Points to get a better understanding).
