[AccessD] Access ---> Drupal?

Dear List,
I have an Access app that I need to migrate to the web. The app basically
tracks company assets. I was originally planning to take a Microsoft route
with SQL Server (or Azure) and .NET. But I've been talking to folks who
swear that Drupal can do it. The advantages: open source, no cost, great
developer community, fast growth, etc. I'm skeptical of using a CMS as my
foundation, but hey, if it works...
Anybody have any experiences converting an Access app to Drupal?
Thanx,
Darrell
