Loading product data from a database

[CCuser]

Already checked forum topics.

I previously wrote a C# windows application which can browse a Window's folder for product images. It will auto re-size the image with the larger dimension being 300 pixels, add a smaller thumbnail image, input title, price, category  and up to 2048 character description. The information is then stored in a MSSQL service database. I can modify for a Joomla required MySQL database, but my question is: How can I use the database to load up product information into VirtueMart?
