Draw an activity diagram exemplifying proper partitioning of whole figure for the
following Change Student Information use case: It starts with the student logging onto the
system by filling out a web form and clicking the Submit button. The form is transmitted to the
web server, which then passes the data to the mainframe computer. The mainframe accesses the
STUDENT database and passes either a “Not Found” message or selected student data to the
web server. If the student record has not been found, the web server displays an error message on
the web page. If the student record has been found, the web server formats a new page
containing the current student data in a web form. The student may cancel the change from either
the Logon system or the Enter change states, and the activity halts. If the student enters changes
on the web form and clicks the submit button, the change data is transmitted to the server and a
program starts running that validates the changes. If there are errors, an error message is sent to
the web page. If the data are valid, the student record is updated and a Change Student Journal
Record is written. After a valid update, a confirmation web page is sent to the browser and the
activity terminates.
