I couldn't find such a beast on my CD. More likely it is something like:
You select package foo.
The installer checks foo's dependencies. It sees if the currently
selected packages satisfy those.
Otherwise it queries other packages available for installation to check
for provider packages. This information would be cached.
The installer selects the provider packages of foo as well.
Of course the actual algorithm would be better than that.

This must be the rpmdb-redhat package. It is an RPM of the database,
assuming all the packages on the CD were installed. Maybe useful in
consistency checks.
