Visio and Databases

[sucoyant]

I have two questions:

1. Can the layout of a Visio diagram (specifically a flowchart) be saved to
a database and be accessed from multiple computers?

2. Please bear with me on this question, I know nothing about shapes. Is it
possible to have a drop-down box in a shape? If so, is it possible for that
drop-down to pull its contents from a database?

Any information would REALLY be appreciated. I would love if someone could
answer these questions and possibly point me in the direction of a few
resources.

Thanks!
