hi im really thankful for this website for this is my reference in my studies taking up computer science.
i would like to ask for help and advice regarding database design what would be the best design regarding
water billing system.

members pay their bills base on water consumed (present reading minus previous reading), and payment is
accepted thru cashier with either balance or advance payment.
