Poll system multiple answers

If you would want to make a poll system that supports multiple answers (options) (not just yes/no) how would you do it? How would you structure the db etc?

I don't want to limit the answers/options.

Some input on开发者_JAVA技巧 this would be greatly appreciated.

Here is what I used:

Pool table:

pool_id: int
pool_name: varchar
number_of_votes: int

Pool_question table:

question_id: int
pool_id: int
question: varchar
answer: varchar
question_selected_count: int
