Explanation of Solution
Course table:
This table tells about the courses that are taught at the university.
Table creation:
CREATE TABLE COURSE (CourseID int primary key, CourseName varchar2(10));
The above query is used to create a table named “COURSE” with two columns named “CourseID”, and “CourseName”.
Inserting values:
INSERT INTO COURSE VALUES (101, 'Mathematics');
INSERT INTO COURSE VALUES (102, 'Computer Science');
INSERT INTO COURSE VALUES (103, 'Information technology');
The above queries are used to insert values into the table named “COURSE”.
After creating and inserting values, view the table by executing the query “SELECT * FROM COURSE”.
Screenshot of the table “COURSE”
Faculty table:
This table tells about the professors who teach those courses.
Table creation:
CREATE TABLE FACULTY (FacultyID int primary key, Name varchar2(10), CourseID int references COURSE);
The above query is used to create a table named “FACULTY” with columns named “FacultyID”, “Name”, and “CourseID”.
Inserting values:
INSERT INTO FACULTY VALUES (111, 'Adams', 102);
INSERT INTO FACULTY VALUES (112, 'Charles', 103);
INSERT INTO FACULTY VALUES (113, 'Bekki', 101);
The above queries are used to insert values into the table named “FACULTY”.
After creating and inserting values, view the table by executing the query “SELECT * FROM FACULTY”.
Screenshot of the table “FACULTY”
Student table:
This table tells about the students who takes those courses.
Table creation:
CREATE TABLE STUDENT (StudentID int primary key, StudentName varchar2(10), CourseID int references COURSE);
The above query is used to create a table named “STUDENT” with columns named “StudentID”, “StudentName”, and “CourseID”.
Inserting values:
INSERT INTO STUDENT VALUES (201, 'Zara', 102);
INSERT INTO STUDENT VALUES (202, 'Ryo', 101);
INSERT INTO STUDENT VALUES (203, 'Maya', 102);
The above queries are used to insert values into the table named “STUDENT”...

- Need help with these:Design a While loop that lets the user enter a number. The number should be multiplied by 10, and the result stored in a variable named product. The loop should iterate as long as the product contains a value less than 100. 2. Design a For loop that displays the following set of numbers: 0, 10, 20, 30, 40, 50 . . . 1000 3. Convert the While loop in the following code to a Do-While loop: Declare Integer x = 1 While x > 0 Display "Enter a number." Input x End Whilearrow_forwardConvert the While loop in the following code to a Do-While loop: Declare Integer x = 1 While x > 0 Display "Enter a number." Input x End Whilearrow_forwardPython - need help creating a python program that will sum the digits of a number entered by the user. For example if the user inputs the value 243 the program will output 9 because 2 + 4 + 3 = 9. The program should ask for a single integer from the user, it should then calculate the sum of all the digits of that number and output the result.arrow_forward
- I need help with this in Python (with flowchart): Im creating a reverse guessing game. Then to choose a random number from 1 to 100 and the computer program will attempt to guess it, displaying the directions calculated or not. The guess will be displayed and the user will answer if it was correct or not. If correct, the game ends, if not then the computer asks if the guess was too high or too low. Finally inputting an answer and the computer generates a new guess within the proper range. Oh and to make sure the program doesnt guess outside of the ranges produced by the inputs of “too high” and “too low”. The program ending when the user guesses correctly or after the program takes 6 guesses. HELP ASAP!arrow_forwardI need help with this in Python (with flowchart): Im creating a reverse guessing game.

- Having error in pseudcode; wanting to get five sets of two numbers each, calculate the sum of each set, and calculate the sum of all the numbers entered. Not functioning as intended and can't find the error.Code: // This program calculates the sum of five sets of two numbers. Declare Integer number, sum, total Declare Integer sets, numbers Constant Integer MAX_SETS = 5 Constant Integer MAX_NUMBERS = 2 Set sum = 0; Set total = 0; For sets = 1 To MAX_NUMBERS For numbers = 1 To MAX_SETS Display "Enter number ", numbers, " of set ", sets, "." Input number; Set sum = sum + number End For Display "The sum of set ", sets, " is ", sum "." Set total = total + sum Set sum = 0 End For Display "The total of all the sets is ", total, "."arrow_forwardNeed help converting loops!1.
