Then we will have to agree to diverge ;-)

If I ever get my app off the ground, it will be an all-purpose, 
multi-company, multi-currency, multi-everything accounting/business system.

There is a massive market out there, and a large percentage of that is 
Microsoft-only shops. I have no intention of cutting myself off from that 
market before I even start.

I am very happy with my choice of 3 databases -

1. sqlite3 - ideal for demo purposes and for one-man businesses

2. Sql Server for those that insist on it

3. PostgreSQL for every one else, and my recommendation if asked
