A loan company wants to design a database to track student loans. Each student attending school is eligible for a loan. A student may have more than one loan. A student may be registered, possibly at different times, in more than one school. Each loan should belong to only one bank. Each bank can approve as many loans as it desires. For each loan, the loan company will track: the student’s SSN, name, address, amount of loan, date of the loan, interest rate ( which may be different for each loan as determined by the bank), duration of the loan, monthly payment, remaining balance, school ID, school name and address, number of years the student has been at the school, bank name, bank branch, and bank ID. Draw an ER diagram. State any assumptions you make in the diagram
