The Reverse Database to Model feature allows you to create a database model from an existing database or schema.
Navicat provides a step-by-step wizard for you to complete the task:
In the Workspace window, choose Tools -> Reverse Engineering -> Reverse Database to Model.
Select the source connection, database, schema, and select the target model, database, schema. Choose New Model and the model type if you want to create a new model.
Click Next.
Select the objects you want to import.
Enable Import To Diagram and select a diagram if you want to add the objects to a diagram. Choose New Diagram if you want to import objects to a new diagram.
Click Start.
You can also simply create a new model diagram using reverse engineering in the Navicat main window. For example, right-click an opened database and select Reverse Database to Model.
