Answer 2

Step-by-step explanation:

hey!!

The definition of cardinality, which is important for executing an query, is data cardinality. It's all about how many distinct values are in a column. ... When applied to the database, the meaning is slightly different: the number of specific values given in the table column, relative to the number of rows in the table.
