Define non-default database using hook_schema?

Hi

Please correct me where I am wrong.

I am assuming that the implementation of hook_schema() is for drupal_install_schema() is to install a module's schema into the default database used also by Drupal's site components (nodes, menus, views, etc...).

However, is it appropriate to alter where to load implemented hook_schema() besides using default when calling drupal_install_schema()?

For example, if in settings.php there is defined two database aliases: default and example. And in the implementation of hook_install() for an example module example, have it be:

function example_install() {
  // Choose Database 'example'
  db_set_active('example');
  // Load schema into example database
  drupal_install_schema('example');
  // Return to Database 'example'
  db_set_active('default');
}


function example_schema() {
 // Tables for Database 'example'
}

Is this an appropriate Drapal database install?

Thanks
