INTRODUCTION
Student enrolment system will bring a lot of impact on the education industry where it has
large number of population, its use registration system manually, its primary aim is to automate
system of student admission, select an appropriate course. The system is mainly divided into
different parts: back ground information of student, campus. The online system provide better
quality of facilities to student where they can easily access information through system. in order
to establish interaction with faculty members and build understanding towards particular subject.
The report will describe about the context diagram, data flow which mainly representing as high
level of process and also establish relationship between them. Furthermore, it will identify the
non-trivial processes from level 0-DFD which automatically decompose each process into
explicit one level. However, it will create an entity relationship diagram that shows as relation
among different entities.
TASK 1
Create and document a context diagram for system.
A context diagram is defined as process where it will be divided into different level, in
order to show boundaries of enrolment system. In this way, it can be identified the flow of
information between system as well as external entities. The while system support, shown into
single process. In another way, context diagram is primarily display that how system
interoperates at high level, interact with logical manner (Akbulut-Bailey, 2019). The student
enrolment system, context diagram help for developing an important baseline which
automatically interact with system and actors.

TASK 2
Develop and design level of 0 data flow diagram, identify that how should contain high level
processes of system and established the relationship.
A data flow diagram is an interactive way of representing the flow of information or data
in a process within enrolment system. DFD provide the information about the specific input as
well as output of each entities. It has no specific control flow that control overall processing.
There are no specific decision loops, rules.
0-Level data flow diagram
This level of DFD have been elaborated with the high level process of student enrolment
system. In this way, it can easily explain the basic overview of entire system or process.
Sometimes. It useful for analysed or modelled according to requirement of users (Davis and Yen,
2019). It is designed to be interactive way to show authentication, student login which mainly
representing as single high level process, with its develop relationship to external entities that
applicable within student enrolment system. Therefore, it become easier to understand the
people, including course, subject and enrolment. The Zero level data flow diagram has described
high level flow of system.
High level process flow within system:
 Managing login details
 Managing and controlling student information
 Handle tuition fees payment process
 Managing course
 Managing subject, authentication
