How to setup a data base for forms

Hi,

How would you setup the data base for a forms ?
I didn’t find any thing about it on the forum.

Actually my structure is :

    1. Data type (users) with
      Fields 1 : name
      Fields 2 : relation list of forms (multiple)
    1. Data type (Forms) with
      Fields 1 : ID Forms
      Fields 2 : Relation with user (single)
      Fields 3 : Relation with Questions (multiple)
    1. Data type (Questions) with
      Fields 1 : ID Questions
      Fields 2 : Relation with Forms (single)
      Fields 3 : Relation with answers (multiple)
    1. Data type (Answers) with
      Field 1 : ID answers
      Fields 2 : type answer Text
      Fields 3 : type answer Number
      Fields 4 : type answer Image
      Fields 5 : type answer Bool
      Fields 6 : type answer Date

I am really not sure my Data type Answer is the right way to do it.

Thanks for your help
