In Luna Modeler, all database connections are available in the Connections section.
How to create a new connection to your Oracle Database
To create a new connection, click the Connections button on the main toolbar, and then click Create New Connection. A new modal form opens. Select Oracle and enter the connection details.
When you are finished, click the Save Connection button. Your new PostgreSQL connection will appear in the list of all database connections.
Loading existing database structures
To start the reverse engineering process and to create a project with an ER diagram, navigate to your connection and click Connect and load the existing database structure.
As a result, you will see the ER diagram for your database structure. If you reverse engineered multiple schemas, you might find it useful to enable the Display schema mode.
In the Professional edition of Luna Modeler, you can also split the main diagram to multiple sub-diagrams by schemas.
If you wish to visualize another Oracle Database, either create a new connection or create a copy of an existing connection by clicking the Duplicate link.
