Hi all,

I have a large quantity of data ( several millions ): several view's uses the same data

Approach 1:

Using one table, we can store all the data and several views can access that table

Approach 2:

Using several tables, we can store all the data and different sets of views can access these table

Which approach is the best one for performance?

Babu

Will you need to JOIN the views or all view will display only subset of column from the table?

If you must JOIN the views - then ONE table approach is (usually) better, because it eliminates the need for join, however it depends on the number of columns in your table and the row length as well.

HTH.
