How to look up a value based on another entity

I have two entities, Employees and Projects. The Project Entity has multiple attributes (e.g. Owner, Developer and Lead) that I want to limit to records in the Employee entity.  What is the best way to do this?

I am guessing the owner, developer and lead should be employees. In that case you can set associations from the project to the employee, i.e one for owner, one for the lead.

If there is only one owner(employee) you make the association *-1 from project to employee.
If it  is possible to have more developers(employees) you make the assocation *-*
