Object Design query

[N_K]

Hi,

I'm designing a system in ASP.Net using VB.Net.

I have an object called Uer which will house a user's email address and password. I want each user to have its own Address object also which holds name, address, country etc.

What i need to know is to I make one of the properties in the User object to be of the type Address and put address info there like an object within and object or do I have the Address as a seperate object linked via a common field such as 'AddressId' say?

Thanks,
