Which Composition graph best represents the following code? (looking for personal preferences)
Where spaghetti "IS" pasta that "HAS" meatballs and sauce.

| Of the 4 options, just looking at the pictures on their own, and thinking about code structure, I would say A is my preferred option. But to try and represent the statement, definitely B, which better reflects what is happening. |

A is a hard sell for me because inheritance is upside-down.
B and C are appealing because I see standard inheritance (base at the top, most derived at the bottom, with "is a" arrows in the direction I expect them to be).
D is growing on me but I have to mentally change the meaning of the arrows from "is a" and "has a" to "is the base of" and "is in."
And an additional disconnect because it uses the same link colors as "is a" and "has a."
The question "Is water used in spaghetti?" for me is most easily answered by D but I'm not sure how often that question matters. |

I would also say B.
However, I think it would be even better if the "HAS A" link were more like the UML aggregation link for displaying the relationship between "Spaghetti <>--- Meatballs" and "Spaghetti <>--- Sauce".
I know that this wouldn't be perfect (the tool probably couldn't reasonably distinguish between aggregation and composition, for example), but I think displaying links more like UML lets the diagrams be more readily understood at first glance by someone, since UML is a widely documented and used diagram standard. Even if the diagrams aren't full-blown UML, using UML where there's reasonable UML to be used will make the diagrams less confusing. Why invent your own diagram 'language' when there's one already out there? |
