Virtual Entities

In this section the user administrator can manage the Virtual Entities: a set of queries over the ontology that can be used by external BI tools.

In order to create a new query please read the Graphical Queries manual. Once you saved the set of queries (consultable in the left side menu) and started a Mastro Endpoint the virtual entities will be accessible by the OData protocol by Power BI (or similar).

OData Button

Just click on the button to copy the URL, then paste it in the Power Bi source of type Feed OData and you are done! You can exploit the power of any OBDA specification and BI tools together in a fully integrated way.
