mysql - Simple survey database design -


I am creating a survey for the visitors of my event, though it was a time since I created a database, need help.

I find some solution but they are in widespread and there is no such thing.

Visitors need to be anonymous, but they can leave them behind the email (separate table emails which are not related to ATMs) They have approximately 20 questions, some are open, some are There are options (radio) and there are several options (checkboxes). The questions need to be reused. I do not know how much you have to go beyond a lot of people in the picture below. survey database design

How do I go from here? Should there be a relationship with an answer table? With surveys or with questions?

Edit:

In the following link, most of the surveys are based on classic design patterns. One of my surveys is more information in the following link:

I possibly take a survey The user's event may have a host named "User_Answer_Session", which contains surveys and links to the user; And then "User_Answers", which are connected to the session and are included in the actual blob of the question and answer. How I'm Absolutely based on some things (mainly, I wanted to be able to see them in a powerful way). For example, do I want to be able to index multiple-choice answers for highly intense reporting? If so, then you need a model for it. It can be included in creating a "Question_Options" table, which is a question-and-a-lot among the available options ...

It should think with a good path. : -)

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
