The Virtual Private Database packages/tables are stored into a new schema and include
grants to the CMS owner schema for executing and reading them.
Obviously a sensitive information such as the password is not granted to the cms owner for
security reason. User only can check for the validity of an specific user/password combination
through a database procedure.
The owner schema which contains the CMS assets creates sinonyms to the packages and tables
stored into the VPD schema.
