Question : Import and export rows in Access 2003?

Hi,

I have an Access 2003 database application that has tables of linked "static" data that are only editable by the administrator, and several interlinked tables of "user" data that can be customized and added to by users. The database administrator wants to be able to update the "static" data periodically, but does not want the users to lose the data that they've already added. Is there a way to import multiple tables of linked data using VBA?

Thanks to anyone who can help...

...Jay
