Question
In MYSQL database, if a table, Alpha has degree 5 and cardinality 3, andanother table, Beta has degree 3 and cardinality 5, what will be the degreeand cardinality of the Cartesian product of Alpha and Beta?
Solution
To find the degree and cardinality of the Cartesian product of two tables, Alpha and Beta, we need to multiply the degrees and cardinalities of the individual tables.
The degree of the Cartesian product is the sum of the degrees of the two tables. In this case, the degree of Alpha is 5 and the degree of Beta is 3. Therefore, the degree of the Cartesian product of Alpha and Beta will be 5 + 3 = 8.
The cardinality of the Cartesian product is the product of the cardinalities of the two tables. In this case, the cardinality of Alpha is 3 and the cardinality of Beta is 5. Therefore, the cardinality of the Cartesian product of Alpha and Beta will be 3 * 5 = 15.
So, the degree of the Cartesian product of Alpha and Beta is 8 and the cardinality is 15.
