Hi,I have 5 tables related among them so that:* T1 is parent of T2 * T2 is parent of T3* T3 is parent of T4* T4 is parent of T5However, in some cases one table is missing so that:* T1 is parent of T3 * T3 is parent of T4* T4 is parent of T53 relations in total.And yet, in some cases an additional table is missing so that:* T1 is parent of T4,* T4 is parent of T5The 5 tables always have the exact same fields but, of course, the relations are different among each case.Is there a way to design the schema so that I always have 5 tables and make T2 and T3 "invisible" for cases #1 and #2?Or should I consider 12 tables: 5 for case #1, 4 for case #2 and 3 for case #3.I will very much appreciate your feedback.Respectfully,Jorge Maldonado
