In the survey, there is a type of question called Matrix which it’s like this:

          | Is Friendly | Weather | Comments
===========================================
Sydney    | Y           | 5       | 'bla'
-------------------------------------------
Singapore | Y           | 10      | 'test'
-------------------------------------------
Jakarta   | N           | 0       | 'test2
-------------------------------------------

Try to get a feedback in term of designing SQL table for question and answer. I could have a design that you can only have 3 label sets (Is Friendly, Weather, Comment) or maybe extended to 10 to be save which means I have 10 columns.

What do you think about this approach, I know this is not relation database in such but at least from query point of view for answer to pull out.

Your thought?

    In Sql Server you can make use of PIVOT.

    This will allow you to design the table differently.

    You would then have a table with columns

    • EntryType (eg. IsFriendly, Weather, Comment)
    • City_Region (eg. Sydney, Singapore, Jakarta)
    • EntryValue (eg. Y, 5, bla)

    This will basically give you the functionality to have “dynamic” columns.
