osCommerce & MS SQL?

Hello Friends,

I'm evaluating osCommerce and wondering if it integrates with MS SQL?
It comes with MySQL, but we have already developed a content management system that uses an MS SQL database and we would definitely need to use that data with osCommerce.

We'd also want to make some extensive modifications to the osCommerce website, so that it ties in not only to our content database, but also to our MS SQL database containing periodically updated accounting data (AR, sales, inventory,...).

Does this sound possible with osCommerce?

Thanks!
