For training courses from Denodo 8.0, I always recommend to use the Virtual Machine. So here I recommend you to refer **Vitual Machine Configuration** of the on-demand course, which will breif you the Denodo Training QuickStart Virtual Machine and Oracle VM VirtualBox.
Please refer to the **Denodo Training QuickStart Virtual Machine - User Manual** which is available in the downloaded folder of the VM. It will provide you more details on VM Settings and also to Open ip address command in the terminal. Eventually, **Training resources** section of the on-demand courses to know more information on using the Denodo Express.
Hope this helps!!
