Designing Feedback database table
<p>What attributes should be in the Feedback table? </p>

<p>First of all I do not require any login for feedback. So I'm putting the following column in my table:</p>

<p>For Example</p>

<ol>
<li>Subject = that about what is the purpose of feedback.</li>
<li>message = description of subject.</li>
<li>contact Number</li>
<li>Email = to contact the user or replay the answer to subject</li>
<li>Name = for calling the user purpose<br></li>
<li>FeedBack_Date= TIMESTAMP ON UPDATE<br><br>
Do I need any primary key in my table? And if so, why do I need the primary key? Any suggestions?</li>
</ol>
