Project Preliminaries
The project is being conducted by the AusEd Inc organization which provide online
education to students all around the world. The main subjects that are being taught by the
organization are infromatgion Technology and Business. The organization is looking to
develop their online education system that would help the students across the world in
receiveiung education without actually having to vist the instiututions. The proejct is to
develop an accounting infromation system for themselves so that they can diversify tgheir
business and the reduce the overall cost for their business. The organization is looking to
upgrade oon the already adopted MYOB software and add an off line moodel in the system
and the ctreate photo exams on the system.
System services
The description of the system services that are planned by the organization are
provided below:
Off-lin Moodle:The students would be able to matian their personal details on their system
which is available on all the platforms such as Windows and MacOS. In additon to this, when
the student goes online the personal data of the students stored on the local database in the
system of the student would be synchronized with the data in the server of the organization.
Photo Exam: The photo exam is the one in which the students can give the tests from their
system. The eaxmination would open in the systems of the student provided they are
connected to an internet connection in their personla computers. The photocopies of the
examintaions would be stored effeciently in the system of the students. The data in the system
of the student and the current location of the system is also copied by the server.

Online courses: The students would be able to access the systems and log in to the online
education systems. The student would be able to access all the course lecture materials and
the other required resources from the systems.
System context daigram
Description of the context of the system
The main process is the online education system. The system aims providing the
student educstions online so that they are not required to vists the institutaiuon to receive the
educations. The main entituies if the system are the students, evaluators, tutors and
theaccounts that would be interacting with the systems and the messages in the systems
would be flowing from the eneties to the system and the vice versa. The students would be
able to perform the actions such as logginh into the system, registering into the system ans in
return they would be fecthing the course details and the study materials from online system.
In addion to this, the tutors would providing the education online on the system and they
would be receiving salary from the system in return. The evaluators would be retreiving the
assignements submitted on the system from the database in the server of the organization and

in return the feedbacks would be sent on the system by the evaluators. The accounts entity
would deal with the payments and finances in the system. The accountgs would receive the
payments from the students and in return the invoices would be returned to the student via the
system from the accounts entity.
System functional requirements
The functional requiremnets of the Aus Ed Inc online education system is used by the
students to asisst them in their education. The main funcational requirements of the system
are registration, and uploading and downloading of important study materials online and
storing them on online data storage area.
Lists of system functions
The list of funcations of the system are provided below:
Function Descriptions
Login The students would be able to login in to the online courses with
the login credenatials provided to them.
Registration The students would be able to provide the details on the system
and perform the registration operartions.
Select Course The student would select a course on the system after logging into
the system.

provides a number of actors for the system. The main actors identified in the system are
Students, tutor and evaluator. The main functions that are idenfied by the system are Login ,
resgitration, assginment selction functions. The other functions in the system are assigment
upload and download options. The student actor performs the login and resgitration
funcations. The lectures notes are downloadable by the students and the lecture notes are
uploaded by the tutors. The evaluator actor performs the action of dowloading assignments
and submiting feedback in the system. The tutor actor peforms the performs the task of
uploading the lectures in the system.

System constraints
The system would be useful for the students as they would be able to go online and
select the courses desired by them and also they can gain important infromations about the
course from the system. They would be able to make payments for the courses they enrol
themselves into. The tutors would also be able to performs several functions in the systems.

However, there are various funcations which are out of scope of the system. The interaction
in between the students and the tutors are very difficult in the system. There is no
communication options or chatting options available in the system. In additon to this, the
system has different login credentials for the different type of users on the system. The login
id and password for that of the students are different, than that of the tutors or the staffs in the
systems. Hence, with implementation of a few tools that would be helpful in the
communication process within the system.
