Hi. For an example let me say that I have a big (over 1 million) user "base". Then every user does a lot of inserting/updating of data. Would it be better to create different tables for insert/updating for every user or would it be better just to have one big table with all data (tables would have of course the same columns, ...). How do you cope with this kind of things? 1.example (1 enormous table) tablename (id, user_id, datetime, some_data) 2. example (a big number of tables) tablename_user_id( id, datetime, some_data) Thank you.
