Hi Joseph,

I don't know what you want to model. Assuming the accounts already 
exist, you can attach each transaction to the account. But then you 
would need a collection of accounts somewhere.

In that case each account will have a collection of transactions. OTOH 
if you need your transactions to replay them all on a 'database' (like 
Smalltalk's changes file or the transaction log of a rdbms) it's useful 
to have a second collection where you also put the transactions in.

Basically if you have many of anything you put them in a collection and 
use the powerful collection protocol do deal with them.

Sorry for being so vague but I hope to get the message :-))

Cheers

Herbert
