You want to store rows with an object id, a field or fields storing the
hour and the 8 object fields (assuming these fields shouldn't also
be one per row - but without any more knowledge about them I can't say).
You should put a primary key constraint on the object id and the hour field(s).

Without seeing what you are going to do with the data it is hard to say
if using a dbms is overkill or not.
