Question

Samediff banks manager is excited to consider updating their account system. An expert has advised that they would be able to increase both security and ease of maintenance by using object oriented concepts such as polymorphism. Create an inheritance hierarchy that a bank will use to represent customers’ bank accounts. All customers of Samediff bank can deposit (i.e., credit) money into their accounts and withdraw (i.e., debit) money from their accounts. Each month they process interest earned and penalties on each account. Specific types of accounts exist. Each type of account you will need to consider in your inheritance hierarchy is listed below.

Steps taken for this phase:

1. (3 points possible) Visit the original UMLs and revise them based on the information learned up to this chapter Collaborate work among your team members to develop/revise the first UML diagram.
2. (3 points possible) Collaborate work among your team members to develop/revise the second UML diagram.
3. (3 points possible) Collaborate work among your team members to develop/revise the third UML diagram.
4. (3 points possible) Revise the fourth UML diagram.
5. (3 points possible) Connect the classes using an inheritance hierarchy and object composition (if any) for Samediff Bank’s account system.
6. (2 points possible) Based on the information below, what functions should be polymorphic and use dynamic binding for security?
7. (2 points possible) How do you keep track of multiple accounts from a single customer? Explain your thoughts....

Account Type	Monthly Interest (APY)	Withdrawal Penalty	Maturity Penalty
Savings	1.05%	Balance < $1000.00=$50.00	$0.00
Checking	0.02	$0.00	$0.00
Certificate of Deposit (CD)	3 months 2.5% 6 months 3% 1 year 5%	<3 months deducts 10% <6 months deducts 20% <12 months deducts 50%
Money Market (MMDA)	1.25%	Balance < $10,000 = $200		$0.00
