Answer:
Explanation:
Transitive dependency
In this case, we have three fields, where field 2 depends on field 1, and field three depends on field 2.
For example:
Date of birth --> age --> vote
Partial dependency
It is a partial functional dependency if the removal of any attribute Y from X, and the dependency always is valid
For example:
Course and student these tables have a partial dependency, but if we have the field registration date, this date will depend on the course and student completely, we must create another table with the field registration date to remove this complete dependency.
If we remove or update the table registration date, neither course nor student must not change.
Answer:
if (x > 7 && Math.sqrt(x) < 3)
Explanation:
The previous condition checks if the square root of x is less than 3, but this would raise an error if x is a value equal to or less than 0.
So, the condition checks for the value of x before evaluating the square root after the AND operation to prevent an arithmetic exception.
