Identifying Calling Applications
Identifying Calling Applications
The last task to perform before generating the applications is
to identify those that need to call other applications, by asking
the following questions about each:
• Is the purpose of this application to display general
information about a particular subject? If so, does another
application display detailed information about the same
subject?
The purpose of the "project-info" application is to display
general information about a project. If a user wants detailed
information about an event associated with that project, he or
she must use the "event-detail" application. For this reason,
a user of the "project-info" application should be able to
call the "event-detail" application.
• Is one purpose of this application to enter data? If so, will
some users of the application need information from another
application to complete an entry in this one?
The purpose of the "employee-assign" application is to enter
data that assigns an employee to a particular event within a
project. When using this application, a project manager
enters an employee identification number to assign an employee
to an event. If the project manager does not have a current
list of employee numbers, he or she must use the "look-up"
application to obtain the correct number. For this reason, a
user of the "employee-assign" application should be able to
call the "look-up" application.
• Is there a logical order in which the applications should be
used?
The purpose of the "project-entry" application is to enter
information about a project and the events associated with
it. After entering this information, a project manager can
assign employees to each event. A project manager cannot
assign an employee to an event until that event exists. For
this reason, a user should be able to call the
"employee-assign" application only from the "project-entry"
application.
