Question { PCS, 8517 }

what happens if cardinalities are not resolved?

Answer

If Cardinalities are not specified between the tables i.e
the relationship between the tables ( 1-1,1-MANY,MANY-MANY)

We get more results at report level more than the actual
result,like a Cartesian product.

We can't detect the Loops & Traps
(Chasam & Fan) Which are mainly detected by the
CARDINALITIES option

so it should be Identified.
