Hi all, Say we have a collection T_1, T_2,...., T_n of tables. I would like for any pair to be related. Would it work if I where to select any field, say the primary key PKT_1 for T_1 and insert it (albeit artificially) meaning include it as an attribute in every other table? If we did this, any two tables would then have PKT_1 in common. Would this work?
