Question
A table student consists of 5 rows and 7 columns. Later on 3 columns added and 2 rows deleted. After some time 5 new students added. What will be the degree and cardinality?
✓
Answer
Degree – 10
Cardinality - 8
Initial table: 5 rows and 7 columns
Later 3 columns added: 10 columns
2 rows deleted : 3 rows and 10 columns
5 new students: 5 rows
Degree = 10 (i.e. 7 + 3 = 10 columns)
cardinality = 8 (i.e. 5 – 2 + 5 = 8)
Cardinality - 8
Initial table: 5 rows and 7 columns
Later 3 columns added: 10 columns
2 rows deleted : 3 rows and 10 columns
5 new students: 5 rows
Degree = 10 (i.e. 7 + 3 = 10 columns)
cardinality = 8 (i.e. 5 – 2 + 5 = 8)
