title: Oracle Database Object - Last DDL vs TIMESTAMP
body: <p>I am trying to determine which date would be reflective of the time an object was modified on an <code>Oracle 11g</code> database.</p>
  
  <p>last_ddl_time or Timestamp</p>
  
  <p>I have read a number of threads but can't find a clear cut answer. If I am understanding correctly, there are certain events that will trigger the last DDL date to change but not the TIMESTAMP? </p>
  
  <p>Could anyone elaborate. I have a beginner level understanding so patience is appreciated. </p>
  
  <p>Thanks</p>
