Designing a data model for a survey; building the relationships
Table 1 - Questions

Table 2 - Users

Table 3 - UserResponses

If your answers could be more than just yes or no 1 or 0, you might also want a question_answers as a 4th table.  With this you could then use multiple choice with more than 2 choices.

UserResponses will be a many to many relationship or a junction table because a user might answer more than one question and a question will be answered by more than one user.  

The UserResponses table will reference the Users table primary key and the Questions table primary key as foreign keys.
In the case where you want multiple choice, not just yes/no, the UserResponses table will also have a foreign key relationship to the Question_Answers table.
