Help needed in Identifying dependent objects

Question

Hi all,
Basically I need to identify the object related to Integration which is not there in one of our software product under development as compare to other(existing) already developed so that we can apply them in the product being developed.
I need to find these below from few of the packages given to me
     dependent packages/functions to read and update data
1)     Tables
2)     Packages
3)     Triggers
4)     Views
5) Jobs
I would request you to help me in carrying out this faster, I have plsql Developer tool, how to start with so that i m not mess up with and complete it faster.
Regards,
Asif.
