title: How to see the table relationships in ORACLE
body: <p>I had an Access database.</p>
  
  <p>Now I have created a connection with this Access DB and copied it to ORACLE.</p>
  
  <p>I hope the keys and constraints must be recreated in Oracle.</p>
  
  <p><strong>I couldn't find out how to create the relationships between the tables.</strong></p>
  
  <p><strong>And also visualizing them.</strong></p>
