Multiple reference to the same table.

[#1]

Hello.

I have problem with multiple references to the same object in model layer.

Let's say I have two tables :

ADDRESS_TABLE(

     ADDRESS_KEY,

     SOME_COL1

)

TRANSACTION_TABLE (

     SHIPPING_ADDRESS_KEY,

     PAYMENT_ADDRESS_KEY,

     SOME_COL1.

     SOME_COL1

)

To set proper relation between tables I'm forced to create two dynamic tables from address.

SH_ADDRESS_TABLE(

      ADDRESS_KEY AS SHIPPING_ADDRESS_KEY,

     SOME_COL1 AS SH_SOME_COL1

).

/* retrieved from RESIDENT ... */

PAY_ADDRESS_TABLE(

      ADDRESS_KEY AS PAYMENT_ADDRESS_KEY,

     SOME_COL1 AS PAY_SOME_COL1

).

is there any smarter way to do that? Do we really create copy of data or we are referring to the same physical place in memory?

I think you're model is correct.

The address table has 2 roles, shipping and payment.

2 roles, 2 tables.
