How to generate an entity-relationship (ER) diagram using Oracle SQL Developer

Question

I want to use Oracle SQL Developer to generate an ER diagram for my DB tables but I am new to Oracle and this tool.

What is the process for creating an ER diagram in

Answer 1

I'm running SQL Developer 17.2.0.188 build 188.1159 which does indeed contain data modeling capability. I just created a relational model diagram via the menu: File->Data Modeler->Import->Data Dictionary....

I also have the stand-alone Data Modeler, which does the same thing.

As the Data Modeler tutorial states:

Figure 4: Relational model and diagram for HR

The diagram you’ve generated is not an ERD. Logical models are higher abstractions. An ERD represents entities and their attributes and relations, whereas a relational or physical model represents tables, columns, and foreign keys."
