ASSUMPTIONS

Since no technological requirements were specified, I was free to use any stack.
In the ERD, Address being a number instead of a string was a typo.
Customer cannot exploit the monthly increment to a savings account by depositing money right before the increment and withdrawing it right after the increment and repeat.
