数据库多选和评论结构

Question

I've read a lot of pages but didn't find what I was looking for. I am trying to figure out which is the most appropriate solution for my problem here. I currently got a multiple choice form with 23 questions and 23 comments section (650 characters each, basically a comment per question) and I am not sure if I should go with a single table or if that would be too much.

So basically something like:

id
user_id
date
multiplechoice1
..
multiplechoice23
comment1
..
comment23
status

That will be around 50 columns :/ Is there a better way to do this? Like split the comments on a different table or somehow combine all the multiple choices in a single column? Since each answer will be 1-5.

Example of the question:

How long do you usually surf the NET on a daily basis?

• 0-1 hour
• 2-3 hours
• 4-6 hours
• more than 7 hours

Answer 1

Taking your comments into consideration, being that you don't want to normalize too much and prefer something slightly flattened, I think this may be a proper solution for you.

questions

+----+-------------------------------+
| id | question                      |
+----+-------------------------------+
| 1  | What is your favorite food?   |
+----+-------------------------------+
| 2  | What is your favorite animal? |
+----+-------------------------------+

answers - question 1 has three answers, question 2 has two answers

+----+-------------+-----------+
| id | question_id | answer    |
+----+-------------+-----------+
| 1  | 1           | Spaghetti |
+----+-------------+-----------+
| 2  | 1           | Chicken   |
+----+-------------+-----------+
| 3  | 1           | Sushi     |
+----+-------------+-----------+
| 4  | 2           | Dog       |
+----+-------------+-----------+
| 5  | 2           | Cat       |
+----+-------------+-----------+

answer_data - one person answered "spaghetti" for question 1, one person answered "cat" for question 2, and one person answered "dog" for question 2

+----+-------------+-----------+
| id | question_id | answer_id |
+----+-------------+-----------+
| 1  | 1           | 1         |
+----+-------------+-----------+
| 2  | 2           | 4         |
+----+-------------+-----------+
| 3  | 2           | 5         |
+----+-------------+-----------+

Truthfully I'm not great with MySQL, I'm a T-SQL guy, but the query would probably look something like this:

SELECT q.question, a.answer, COUNT(ad.answer_id) as `Count`
FROM questions q
JOIN answers a ON a.question_id = q.question_id
JOIN answer_data ad ON ad.question_id = q.question_id
GROUP BY q.question, a.answer


+-------------------------------+-----------+-------+
| question                      | answer    | count |
+-------------------------------+-----------+-------+
| What is your favorite food?   | Spaghetti | 1     |
+-------------------------------+-----------+-------+
| What is your favorite animal? | Dog       | 1     |
+-------------------------------+-----------+-------+
| What is your favorite animal? | Cat       | 1     |
+-------------------------------+-----------+-------+
