To be more precise, how SQL updates works when you need to add new records to a view? Will it create new records in all files?

just because you directed this reply to my box, I can answer that this is not right: you can update several (at least it works for two) tables. Also, it's useless to use views for reporting. Here, it's enough to use cursors.
