title: What is the format of connection string that should be used while using ERWin tool for generating ERD for an Oracle database?
body: <p>I have been trying to generate an ERD for some oracle database. While I am doing this via 'Actions'->'Reverse Engineering' option, I get a section that asks me for a connection string. But I am unsure of the format about how we can specify the database and its details. 
  Could someone please help me with this?</p>
  
  <p>Thanks
