Answer 1

There is a companion tool called Oracle Data Modeler that you could take a look at. There are online demos available at the site that will get you started. It used to be an added cost item, but I noticed that once again it's free.

From the Data Modeler overview page:

SQL Developer Data Modeler is a free data modeling and design tool, proving a full spectrum of data and database modeling tools and utilities, including modeling for Entity Relationship Diagrams (ERD), Relational (database design), Data Type and Multi-dimensional modeling, with forward and reverse engineering and DDL code generation. The Data Modeler imports from and exports to a variety of sources and targets, provides a variety of formatting options and validates the models through a predefined set of design rules.
