The following are the basic processes of Boarding School Outing System. Student may enter the outing request such as date, reason, check-out time (check-in time is auto-set at 6.00 PM) to request for outing. The outing request details are stored in 'Outing Request' record. Warden can view the outing request and he/she may approve or disapprove the request. The status of the request is updated in the ‘Outing Request' record. Once the status is updated, a short message service (SMS) notification will be sent by the system to the student and parents. The hand-phone numbers are retrieved from the Student' record. Student will check-out and check-in via this system whenever he/she is about to leave from the school and reports back to the school. The data (date and time) is kept in the existing outing record. Note: **Definition of outing (in boarding school context): A day out from the hostel/school, normally during the weekend. Based on the scenario above: a) Draw a Context Diagram for Boarding School Outing System. b) Draw a Data Flow Diagram (level 0) for the system with general processes, data stores, date flows and sources/sinks.
