The answer depends on your point of view, the purpose of the diagram,
and the general level of theory being discussed. I notice the diagram
refers to DBMS and not RDBMS so in theory it covers hierarchial,
network, and relational database management systems. No one diagram
is going to be perfect.

You could choose to show a layer appoach: disk storage level, database
software level, program interface, network communication interface,
etc ... like Oracle shows in its documentation (I think in the
Concepts manual).
