I have some OO modules that I need to be declared in a particular order and must ensure that code is called in parent modules before being called in the modules that inherit from it.

First is the basic Configuration module, it establishes a DBI connection so has to come first. 

use My::Config 'test';

package My::Config;

sub import {
    my $package = shift;
    my $option  = shift;

    #initialize DB connection here
}

Next is my basic Object-Relational-Model code, it needs that DBI connection from the My::Config module to automatically run some code when it is initially used.

package My:ORM;

use base My::Config;

# Need to run My::Config::import()
# Need to run My::ORM::import() or something similiar

After 'using' the two previous modules, I want to run some more code in the Model. 

package My::ORM::Model;

use base My::ORM;

I guess my question is, is import() being used in modules or is it like any other subroutine, I would have SUPER my way down the Config module to ensure that everything gets called in proper order?

OR? Is there another approach that I am missing that I should try? When these modules are use'd I only need the code to be run once; (for example, I don't constantly need to create a DBI connection once I have one.
