5 pri-key to much???

[ice-9]

Hi,

Im constructing an ERD.
I got rid of all redundancy, but im stuck atm

heres my question:
Is it bad to have 5 pri-key in a entity?
I an work around it when i leave a tiny bit of redunancy,
but in my perfect opinion its better to have no redunacy!
So can i contruct witout getting problems at a later level, relating to the 5 keys entity?

I think it's also very important to look at what fields you are putting as the primary key.
