Hello. I'd like to implement for my DB a mechanism of backup based in inherited tables. I explain it in detail: Idea is simple: table B inherits from table A. Anualy, data from table A is dumped in B. So, from frontend it is posible to access current data (from A) or all data (A + B). Problem is that I'd like also implement a view for A and B, but I don't know what is best way. View(s) must have rules for insert and update. Can view from A access data from B without problem (eliminating "ONLY" from select)?. Is there another better form of implementing this backup mechanism?. I'd not want to reinvent the wheel ;) Thanks for your ideas.
