Question

A table student consists of 5 rows and 7 columns. Later on 3 new attributes are added and 2 tuples are deleted. After some time 5 new students are added. What will be the degree and cardinality of the table?​

Answer 1

The degree of a table refers to the number of attributes (columns) it has. In the case you described, after the 3 new attributes are added, the degree of the table would be 7 + 3 = 10.

The cardinality of a table refers to the number of rows (tuples) it has. In the case you described, after 2 tuples are deleted, the cardinality of the table would be 5 - 2 = 3. After 5 new students are added, the cardinality would increase to 3 + 5 = 8.
