Newbie to the SAP Ecosystem. Signed up for HANA cloud and created a database "testdb" with the user configured for the demo SHINE Data (selecting the option "Configure user for SHINE data". The user configured was "JOHN". When I access the database via the admin tools, it shows me two catalogs one with SAP_HANA_DEMO and the other with my username XYZ.

Why should there be a catalog with the user name? Under the SAP_HANA_DEMO catalog, I could see various tables containing the shine data.

Accessing data via Java

When creating an app we set the data source bindings to point to this database created. However, I can seem to access only tables that are under the username JOHN. I explicitly selected the option "Configure user for shine" so why is this user unable to access the demo database. And as stated previously, why is there a catalog with the user name?
