Answer number 2 and use Java language

Laboratory Exercise:
1. Create a database of salesman:
a. Table Description:
o Salesman Number – Integer – Primary Key – Not Null
o Salesman Name – VarChar
o Quarterly Sales – Real (Float)
Note: input of sales per quarter (1st, 2nd, 3rd, 4th)
Total Sales - Double
Commission – Real (Float)
b. Compute the Total Sales
c. Compute the Commission based on the following:
Total Sales
Commission
10% of Total Sales
<= 5000
<= 10000
<= 15000
15% of Total Sales
20% of Total Sales
<= 20000
> 20000
d. Search a salesman (input must be Salesman Number), determine if the salesman is
existing in the database, otherwise update the record by inputting new values of
Quarterly Sales.
e. Search a salesman (input must be Salesman Number), determine if the salesman is
existing in the database, otherwise delete the record.
f. Display all the record of database.
25% of Total Sales
35% of Total Sales or 15000 whichever is higher
