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.

What is the phase of a waveform ?

allsm [11]

In sinusoidal functions or in waves, "phase" has two different, but closely related, meanings. One is the initial angle of a sinusoidal function at its origin and is sometimes called phase offset or phase difference. Another usage is the fraction of the wave cycle that has elapsed relative to the origin.

OlgaM077 [116]

Answer:

Changing the customer number on a record in the Orders table to a number that does not match a customer number in the customer table would violate referential integrity.

If deletes do not cascade, deleting a customer that has orders would violate referential integrity.

If deletes cascade, customer can be deleted and all orders for that customer will automatically be deleted.

1.Write a Java program to solve the following problem using modularity. Write a method that rotates a one-dimensional array with

Westkost [7]

Answer:

Explanation:

The following code is written in Java and it asks the user for the size of the array. Then it randomly populates the array and prints it. Next, it rotates all the elements to the right by 1 and prints the new rotated array.

import java.util.ArrayList;

import java.util.Arrays;

import java.util.Random;

import java.util.Scanner;

class Brainly {

public static void main(String[] args) {

Random r = new Random();

Scanner in = new Scanner(System.in);

System.out.println("Enter Size of the Array: ");

int arraySize = in.nextInt();

ArrayList<Integer> myList = new ArrayList<>();

for (int x = 0; x < arraySize; x++) {

myList.add(r.nextInt(15));

}

System.out.println("List Before Rotation : " + Arrays.toString(myList.toArray()));

for (int i = 0; i < 1; i++) {

int temp = myList.get(myList.size()-1);

for (int j = myList.size()-1; j > 0; j--) {

myList.set(j, myList.get(j - 1));

}

myList.set(0, temp);

}

System.out.println("List After Rotation : " + Arrays.toString(myList.toArray()));

}
