Can we check Directionality with -HAS- test.
for example, say we have two entities Employee and Address.Now Employee has a address but address don't need to have a Employee so it is uni-directional.
And again if we have two entities Employee and Project.Now Employee has project and project also has employee so it is a bi-directional mapping.
Am I Correct??
