A basic case

The scenarios refer to admin users and end users/clients who are in possession of data perspectives having differentiations in many respects. As the keepers of tables and views in DBMS, admin users can share queries by team work tools so as to dispatch authorization to other end users/clients. Admin users are also the publishers and the administrators of the resources. But to the end users/clients, they are only the consumers of the resources and the creators of rectangular data structures used for analysis, and they can only hold the part of resources by authorization. Of course, in his authorization scope, he can organize and manage his data, such as a locally created query.
