I need to update a database with new data. the data is coming from a database whichhas been in use while other data has been being keypunched and cleaned up. So I will be appendind data from onea tablel named FOO in one database to a table named FOO on another databes. The table has filed which serve as links to other tables, (ie they are the other table's primary keys). How should I do this append without compromising the integrity of the data's relationships?
