Hi guys need some advice. Please consider schema below. ![alt text] : /storage/temp/1237-capture.png I have a staging database which i'm importing from flat files into local SQL server before importing into salesforce. Now this relationship is fine if you have 1 account linked to 1 address to 1 credit card. How would you maintain a relationship between the tables if in a future import an account wanted to have another credit card or address linked to it???
