Poll Database Schema

What is the best database schema for polls? Is one-to-many relationship good for this? I'm thinking about having two tables: ``` poll_questions int id varchar body datetime created_at datetime updated_at poll_answers int id varchar body int votes default 0 int question_id (foreign key to poll_questions.id) datetime created_at datetime updated_at ``` Then there would also be third table for tracking who voted for an answer so users are able to vote only once: ``` poll_voting_history int id int question_id (foreign key to poll_questions.id) int answer_id (foreign key to poll_answers.id) int user_id (foreign key to the id in the users table) datetime created_at datetime updated_at ``` What are your thoughts? Am I thinking about it right?
