Hi there,

I'm fairly new to Objective C and Core Data and have a problem designing a case where players team up one-on-one and have multiple matches that end up with a specific result.

With MySQL, I would have a Player table (player primary key, name) and a match table (player A foreign key, player B foreign key, result).

Now how do I do this with Core Data? I can easily tie a player entity to a match entity using a relationship. But how do I model the inverse direction for the second player ref. in the match entity?

Player
Name: Attribute
Match: Relationship Match

Match
Result: Attribute PlayerA: Relationship to Player (<- Inverse to Player.Match)
PlayerB: Relationship to Player (<- Inverse to ????)

Would be great if someone could give me an idea on this!

Thanks, Stevie.
