Crow's foot notation: Zero or One

[simeonlin]

I think there should be an improvement on the crow foot notation on the relationships.
From Wikipedia: (https://en.wikipedia.org/wiki/Entity%E2%80%93relationship_model#Crow's_foot_notation)

Three symbols are used to represent cardinality:
-the ring represents "zero"
-the dash represents "one"
-the crow's foot represents "many" or "infinite"
These symbols are used in pairs to represent the four types of cardinality that an entity may have in a relationship. The inner component of the notation represents the minimum, and the outer component represents the maximum.

ring and dash → minimum zero, maximum one (optional)
dash and dash → minimum one, maximum one (mandatory)
ring and crow's foot → minimum zero, maximum many (optional)
dash and crow's foot → minimum one, maximum many (mandatory)

Issues:

• At the moment to-many-relationships are marked with three symbols ring, dash and crow's foot instead of only ring and crow's foot.

• And if I mark a foreign-key-column in the List-view as mandatory the symbol stays at 'ring and dash' instead of 'dash' or 'dash and dash'.

(Just found this VS Code-Extension and I'm amazed!) 🥇

Now I know!

But I don't think it's going to be possible for me to revise it now.

I'm preparing for major version 1.0.
The current version only planned to fix important bugs.

Instead, I will reflect the notation you told me in 1.0!

Thanks for letting me know!

Ok, thank you that's fine! 👍

Do you already have a time horizon for 1.0?
Just: Is it about weeks or months? :)
I'm considering using your great tool in my database-courses I'm teaching.

I'm thinking maybe it'll be completed between June and July.
