Last Day a client asked me if I can generate a relational diagram for an oracle schema. He was just preparing a migration and wanted to see how tables are organized in the schema.
In this article we will show how this is possible with SQL Developer . We are using SQL Developper 4.1.3.20
sqldev1
Once SQL Developer started just proceed as following :
Launch File ==>Data Modeler ==>Import==>Data Dictionary
sqldev2
Choose your connection and Click Next
sqldev3
And then after we can choose the schema
sqldev4
In this example we check all tables and click Next
sqldev5
Review the summary
sqldev6
And Then Click Finish
logfile

After closing the log file, we have the diagram
sqldev7

And we also can save the model in a PDF file or an image file
sqldev8

Hope this article will help
