title: normalization and normal forms: database
body: <p>Basically sorry for asking such question.But I got it wrong when I wrote these definitions in my exam about 1,2,and 3rd normal form (Conditions):</p>
  
  <p><strong>1 NF :</strong> </p>
  
  <ol>
  <li>Data in each column should be atomic.No, multiple values separated by commas</li>
  <li>Table should not contain repeating column groups </li>
  <li>Identify each record using primary key.</li>
  </ol>
  
  <p><strong>2 NF :</strong> </p>
  
  <ul>
  <li>must be in 1 NF</li>
  <li>must not contain redundant data, if yes, move it to separate table</li>
  <li>create table using foreign keys</li>
  </ul>
  
  <p><strong>3 NF :</strong> </p>
  
  <ul>
  <li>Must be in 2NF</li>
  <li>Dose not contain column that are not fully depended upon primary key</li>
