Database Access w/SQL Developer Any More Meaningful Examples for report generation

The Document E59996-01 does a fine job presenting us the information required to get set up with the ability to pull data from the database, and I can see much of what we are interested in.... It's the ID references, which don't seem to be consistent between Views/Tables....   So grabbing the Data I want and can see, and making it into a Useful report is a tad bit difficult.

Is there any additional documentation for this content or More Real World Examples of Data Extraction???

   thanks;
