Also consider making multiple sets of data sources, either using the
"domain" Rose::DB data source attribute ("local", "mirror", "main") or
perhaps prefixing the "type" attribute with "local:", "mirror:", or "main:"
Then all you have to do in the classes to get the right db is pick the right
arguments in the init_db method. Here's an example using just the "type":
package My::DB::Whatever;
...
sub init_db
{
my $type = <figure out correct db type for this class>
return My::DB->new($type);
}
The "figure out correct db type for this class" can perhaps look at the
class name and see if it has "::Mirror::" in it or whatever.
