What is the normal cardinality between a Customer entity and a Sales order entity? What does it signify? Why is it the only logical cardinality?
The normal cardinality is 1:M which signifies that one customer may play many orders during a sales period. The cardinality would never be 1:1 . That would mean that each customer was restricted to a signal sale.
