Question

I dont get 1-n relationship.

I have read some articles but still cant figure it out.

I get 1-many, 1:1 and many-to-many.

But what does 1-n mean?

Was it helpful?

Solution

1-n is the same as 1-many

OTHER TIPS

1-n is the same as 1-many. n is just another way of representing an unknown "many".

n could be any number, so this is equivalent to 1:many

Its just another way to say 1 to many

It's another way of expressing a "parent-child" or "master-detail" relationship. For everything parent you have an undefined number (meaning it can lie between 1 and something-bigger-than-one) of children.
