Consider the following relation: CAR_SALE (Car#, Date_sold, Salesman#, Commision%, Discount_amt Assume that a car may be sold by
Nady [450]

Answer:

See explaination

Explanation:

The given relation is:

CAR_SALE(Car#, Date_sold, Salesperson#, Commission%, Discount_amt)

Primary key: {Car#,Salesperson#}

We will first check whether the relation is in 1NF.

A relation is said to be in the 1st Normal form(1NF) if all the columns in the relation have atomic values. In this case, the relation is in 1NF.

A relation is said to be in the second normal form(2NF) if it satisfies the condition that all non keys are completely dependent on the primary key and just a part of the primary key.

In the case of the CAR_SALE relation, the Commission% depends only on the Salesperson# and not on the combination of Car# and Salesperson#. This means that the given relation is not in 2NF. To satisfy 2NF, we make two relationships as given below:

SALE_DETAIL(Salesperson#, Commission%)

and CAR_SALE(Car#, Date_sold, Salesperson#, Discount_amt)

Now both the relations are in 2NF.

For a relation to be in 3NF, no non-key should be functionally dependent on another non key.

In the case of the CAR_SALE relation, it is specified that the Date_sold field determines the Discount_amt. Therefore the modified CAR_SALE is not in 3NF.

To satisfy 3NF, we seperate the non key and the dependent non key and create a different table.

Final Relations:

SALE_DETAIL(Salesperson#, Commission%)

Discount_Detail(Date_Sold, Discount_Amt)

CAR_SALE(Car#, Date_sold, Salesperson#)

In this lab, you complete a Python program that calculates an employee's annual bonus. Input is an employee's first name, last n
HACTEHA [7]

Answer:

The program is as follows (See attachment)

Comments are used to explain some lines

Fname = input("Enter Employee First Name: ")

Lname = input("Enter Employee Last Name: ")

Salary = float(input("Enter Employee Salary: "))

Ratings = int(float(input("Enter Employee Ratings: ")))

#Initialize bonus rate to 0; This will be used if ratings is 4 or 4

bonusRate = 0.0

if Ratings == 1:

       bonusRate =0.25 #If ratings is 1, bonus rate is 0.25

elif Ratings == 2:

       bonusRate = 0.15 #If ratings is 2, bonus rate is 0.15

elif Ratings == 3:

       bonusRate = 0.1 #If ratings is 3, bonus rate is 0.1

bonus = Salary * bonusRate

print(Lname+" "+Fname+"'s employee bonus is "+str(bonus))

#End of Program

Explanation:

The program saves the employee's first name and last name in variables Fname and Lname, respectively

The employee's salary is saved as float datatype in variable Salary

The employee's ratings is saved as int datatype in variable Ratings

For ratings greater than or equal to 4, the bonusRate is set to 0.0; this is done on line 6 of the program

Line 7 to 12 check if employee Ratings is 1, 2 or 3 and the respective bonusRate is used

Line 13 calculates the employee's bonus

Line 14 prints the employee's bonus

The program is ended on line 15
