You are able to view and switch domains using the switch context menu on the project menu or the context button on the main dashboard. You will notice that you already have one domain called NODES, NODES is the default domain name, you can use it if you wish.
To add a new domain, chose the Create One option from the context menu, you will then be able to type a new name into the screen and hit open. A new domain is created.
Adding a new domain will be a little like starting a new project – there will be no tables, concepts, indexes etc available – but don’t worry they are safely stored in the other domains and you can get back to them by clicking on the context menu.
In the event that you want to move all or part of your tables from one domain to another, then you will need to use the export-import functionality in the modeling section.
