How to design insertion and report for customers

Question

I develop a web application in which I provide a web interface for inserting a customer. I model this customer as a class and provide its attributes. I have functions like addCustomer that inserts a customer's details in DB and getDetails() that returns a customer's attributes as an array. I have designed this for dealing with a single customer.
Now I want to list all customers from DB. I think another class should be created with a listing function that has multiple references(multiplicity) for the customer class. It is a easy task to retrieve all customer using a query and display it. But I don't know how to model this. I don't want to create one object for all available customers and display the details of each customer. Then How to model this and how to implement this using classes.
Can U tell me a resource or article that handles similar task.
Thanks.

Hi,
Create a POJO called customer ( plain java object which represent the persistant data ) and a Customer manager which is reponsible for retrieving a list of customer.
So the Customer manager will deal with retrieving the customer list.
