Schema references - blue circle icon with arrow

Hello,

what does this blue circle icon with arrow mean? (Schema references window in Schema Browser)

Recursive.

And in order to understand recursion, first you have to understand recursion.

Are recursive references perfectly fine or this is bad design? Will Oracle have problems to handle this?

Oracle won’t have any problems with it, and there is nothing “wrong” with them. I just had to add an icon to say “recursive” rather than trying to make it to the end of the dependency list!
