title: PL/SQL - How can I check if a Package / Procedure / Function is being used?
body: <p>Hello to whoever sees this. 
  First of all, my knowledge on PL/SQL is pretty much basic to layman. I can read the code, do queries and use PL/SQL Developer to do my research. That's all I'm needed to do.</p>
  
  <p>All I need to know is if a Package/Procedure/Function is being used and/or, last time it was used. Is there a way to see it through queries or functionality of PL/SQL Developer?</p>
  
  <p>Side note: I've found the question bellow, but it didn't fit my needs/ didn't fully understand how the awnsers there could be of use:
