Create a view that joins the tables. This has the advantage that any column in the view (not just one table) is now queryable, and is more efficient than post-query triggers populating other fields (less traffic and fewer SQL statements)

You will need to replace the on-insert/on-delete/on-update triggers to 'resolve' the view into its base tables and do the right thing to each table.
