Efficiency Question

Querying one table is definitely faster than querying 30 tables! By "values" do you mean columns? If so, you probably should be breaking up groups of related fields into different tables to keep with normal-form recommendations for RDBMS table design. Please clarify.

Oh, by values i mean by rows. There will only be about 7 columns. Every table will have these same columns. So instead I should have a massive table as opposed to separate ones?
