I've made an application that manages unstructured data (e.g. News Papers, Receipts, etc...) using Visual Basic 6.0. The application connect to an SQLServer which run on Windows 2000. I dont have a problem (yet) with the performance, but the price of these softwares makes my program very hard to approach the market.
I'm thinking to use Postgres and Linux as my server probabbly RedHat, but I dont have idea where to start.
I really need a lot of help
