There can be a DVD abstract class,a customer class and Bill class
Under DVD Abstract class we can have a number of concrete classes like Fiction,Horror,Romance, Thriller(I am assuming movies in this case).
The customer has one to many relationship with DVD.As one customer can buy many DVD's
Under Bill class we have a list of DVd,totalAmount,Customer details,return Date and Buy Date

class Bill
List<DVD>
totalAmt
Customer customer
Date returnDate
Date BuyDate

class Customer
name
address
occupation
phone number

abstract class DVD
name
Description
dvdNumber
cost

Then concrete classes like Fiction,Horror ,Romance and so on
class Fiction
implements cost method-which will be specific to each class

In the Database we can have two tables called DVD and Customer.Customer will have a foreign key which will point to primary key of DVD(which is DVD number).There will be one to many relationship between Customer and DVD.
