The quantity of occurrences of pairings are as follows:
Specifies the estimated percentage of times entities of the destination Entity Type are paired with entities of the source Entity Type.
Specifies the minimum/maximum or average number (estimated or actual) of entities of the destination Entity Type that can participate in the pairing.
Note: Frequency of pairing and number of pairings become important during database design because they help determine allotted space amounts.
