Your relational models can get big. Bigger than the human mind can easily consume. So instead of generating a report of 2,500 objects, you might want to break down your model to smaller chunks, AKA SubViews.
So let’s open the reports, which you’ll find on the main File menu.
First, we don’t want the main diagram in the report, that’ll give us EVERYTHING. I just want the subview diagram.
So after un-checking ‘include main diagram,’ we need to go look at the ‘Objects’ page.
Now we can define a reporting configuration that defines which objects we want included.
With our configuration saved and now available, we can go back and select it from the Objects panel.
And Our Report!
Note I generated this using 220.127.116.11 of SQL Developer. Also note I noticed there’s a bug where the Subview Diagram links in the navigation bar to the left don’t work. Thankfully the object links work for the data dictionary bits, and you can just scroll down to the diagram.
If we had included the main diagram (remember when we unchecked that box?), our report would have two diagrams instead of just the one here for the SubView.
