Contacts database to invoices
If I have a contacts database and I want to produce invoices, do I modify the contacts database adding in product tables etc, or do I create a new database and import the existing contact records? If I import, won't I have the same info in two places? But if I modify the contacts database, then won't it stop being a simple contacts database?
You can probably tell I'm a novice with relational databases. I'm using FM10 on Mac OSX 10.6.2
