title: What is the best way to store and retrieve data from database
body: <p>Lets say If I am storing student information in database. </p>
  
  <p>I want to store student name and each student's ID,age and email. so is it a good idea to go like:</p>
  
  <pre><code>INSERT INTO student table ( 
      (studentName, age, email) VALUES
      ('John', 25, 'john@example.com')
  )
  </code></pre>
  
  <p>or should i use key value combo ? my main concern is when another student with same name is added and when i retrieve data using student name then ids,age etc get mixed up with another name.</p>
