In Denodo Express, I would utilize the embedded OData 4.0 data service, which can be accessed using the following URL:
> http://localhost:9090/denodo-odata4-service/denodo-odata.svc/<database name>/
This provides with the contents of the Virtual DataPort server. For more information, You can refer to the section[ Denodo OData 4.0 Service](https://community.denodo.com/docs/html/browse/7.0/vdp/administration/restful_architecture/odata4_service/odata4_service#denodo-odata-4-0-service) of Virtual DataPort Administration Guide.
Hope this helps.
