We have an application, below which there is a database where the information is stored.
information used from the users themselves. This database is controlled by staff
administrator from a database manager program external to this application. There are
to take into account both the administrator and the normal user when carrying out the
conceptual models of the considered application?
a) Both must be taken into account, and their corresponding classes must appear in the
requirements document diagrams.
b) The user must appear, since he is an actor of the application and his data is used,
but the administrator does not, because he uses an external program.
c) The user should not appear, but the administrator should, since the latter has more
weight that the user performs the necessary operations so that the application
works.
d) Neither of them should appear, since they are external agents to the system, and
therefore, they should not appear in the system information model, or model
conceptual.
