Layout (a) All diagrams must be drawn using Lucidchart and copied into the MSWord document. (b) Please note that you are NOT required to copy the task description over to the MS Word document. Use the task number to indicate which task your response relates to. References APA style for citing and referencing research Submission 14/04/2020 Task Summary Based on your responses to Assessment 1 – Written assessment, perform process and data modelling and develop and document a number of design diagrams using UML (including Context Diagram, Level 0 and Level 1 Data Flow Diagram, Entity Relationship Diagram). Context In Assessment 1, you performed a comprehensive requirement analysis for the online student enrolment system at the ABC University. With an in-depth understanding of the functional requirements of the System, you are now required to perform further analysis through process and data modelling. In doing so, you also need to provide a preliminary data storage design for the System. Both process modelling and data modelling can be used to provide deeper understanding of a new System. Thus, they are an integral part of System Analysis. Process modelling describe business processes – i.e. the sequence of activities that people do; while data modelling seeks to describe the data flows through those processes. Data flow diagrams (including context diagrams) and entity relationship diagrams are the most common process and data modelling techniques used in industry. Assessment Instructions 1. Please read Assessment 1_Case Study. Please note that every piece of information provided in this case study serves a purpose. 2. Once you have completed reading the case study, please read the attached Assessment 2_Additional case information document. Please complete the following tasks: Task 1. · Create and document a Context Diagram for the System. (15 marks) Task 2. · Create and document a Level 0 Data Flow Diagram (DFD). The Level 0 DFD should contain all the major high-level processes of the System and how these processes are interrelated. (20 marks) Task 3. · Select three major and non-trivial processes from Level 0 DFD, decompose each of the processes into a more explicit Level 1 DFD. (24 marks) Task 4. Using your own experience with similar online student enrolment systems and the information provided in the case study: (20 marks) · Identify all the entities and their relationships in the System. · Create and document an Entity Relationship Diagram (ERD) for the System. Note: the case study has not and does not intend to provide a comprehensive description of entities in the System. You are expected to use your own experience with information systems in general and online student enrolment systems in particular to develop this ERD. For example, would Subject Name be an attribute for a Subject? Would Date of Birth be an attribute for Students? Task 5. Should data be stored in files in a file system or in a database for the System? Justify your answer. (5 marks) Task 6. Translate the ERD you developed in Task 4 into a physical relational database design. Document database tables and their relationship in MSWord file.

Student and staff login credentials are stored in a central database external to the System. Online Student Enrolment System at ABC University ABC University (ABCU) is seeking to develop an online student enrolment system (the System) whereby the students would be able to enrol themselves into eligible subjects at the beginning of each trimester and pay their tuition fees online. You have been hired as the Business Analyst for this project. Founded in Sydney in 2013, ABCU has experienced a remarkable growth in student numbers in recent years and has opened new campuses in three other Australian cities including Melbourne, Brisbane and Adelaide. ABCU currently has 50,000 students across their four campuses with an estimated 5000 student in-take in each trimester. This phenomenal growth in their student numbers has necessitated the need for an online student enrolment system. Once developed, this system will replace the manual enrolment process that is currently in place. The current manual enrolment process is labour-intensive, error-prone, and rather inefficient as it requires the Student Enrolment Officers to manually enrol each student into the subjects upon the receipt of a study plan from the students. The Pro Vice Chancellor (Learning and Teaching) envisage an online student enrolment system which would allow students to complete their enrolments and tuition fee payments before the Census date. The System should not only enable Student Enrolment Officers of each School to create, edit and remove Courses offered by their School but also to create, edit and remove core subjects and electives offered in each course. The students should be able to access the system through a device of their choice (e.g. desktop web browser, mobile phone or tablet app). Most subjects would have pre-requisites that must be satisfied before the students are eligible to enrol in the subject. It would be the responsibility of the Program Directors to provide and update the relevant course and subject information including the descriptor, availability (i.e. whether a subject or a course is offered in a certain trimester) and the prerequisites. The Timetabling Officers may also create, edit and remove timetables for each available Subject through the new System. Each campus will hold multiple classes for the same subject. A Subject is offered in the form of classes. Each campus may offer multiple classes for the same Subject. Once logged into the System, students should be able to view all the available subjects, enrol in and drop subjects. The System will detect timetable clashes and prevent students from enrolling into subjects that clash. The System should not let students to enrol in too many or few subjects unless they have an increased or reduced study load approved by the Student Enrolment Officer. Once the enrolment has been completed the system will generate a timetable customised to each individual student outlining the class times and locations. The System will then prompt the students to pay their tuition fees through a secure payment process. The System should be able to send email reminders to students who have not completed the enrolment process by a designated deadline. It should also allow the Student Enrolment Officers and Program Directors to generate customized reports (e.g. a report showing a total number of students enrolled in a particular subject or a course).

y
The development of EMS system for the ABC University requires development of different diagrams and following related processes. As the stakeholders of this EMS system are identified and their roles are defined, so the functional operation of this EMS system can be defined in graphical manner with help of different diagrams. The development of context diagram will provide help in defining the data flow this important system to ABC University. The different DFD will also help in defining the data flow among identified sub systems of this required system. The identification of possible entities required to implement this system are proposed in the ERD. The university system will handle a data set of large size, thus, recommendations for data storage to this important system for ABC University are also done. The conversion of data tables to 3NF is also proposed for EM system. This will help in fast fetching and easy access to the created data base of ABC University. The development of these diagrams and recommendations will provide easy handling of operation to EM system of ABC University. These all graphical representations are developed on the bases of identified requirements in previous task and defined use cases.
2. Context diagram of EMS for ABCU
The successful implementation of EM system to ABC University requires development of context diagram so that the data flow among all sub systems can easily be maintained. The DFD of 0 level and context diagrams are very similar to each other but the difference among created sub systems and their data flow makes them different. The fragmentation based data flow to all developed external interfaces to EM system of ABC University is mainly proposed with context diagram. This diagram developed for EM System will define the context among all developed data forms maintaining the operations of different use cases developed in previous task. The single process which is defining unique operations of EM system are represented in context diagram. The category based implementation logic of this EDM system is mainly understood by the context diagram. The operational interactions among the identified actors in previous task is properly explained and defined with this pictorial representation. Context diagram showing implementation of EM system for ABC University is provided in pictorial form:
Enlightenment on above presented diagram:
· There are total six sub systems identified for this EM system of ABC University. These will act as the external systems providing support for different operations of ABC University.
· The system with starting from enrollment to their final exam is effectively shown in the context diagram. The involvement of payment, course, and student login are effectively shown as the sub systems of EM system.
· The creation of sub systems to this EM system will allow defining data flow to all created sub systems through this context diagram.
· The involvement of payment processing through this EM system will allow effective operations to this ABC University.
3. DFD (0- level) diagram of EMS for ABCU
The implementation to any system requires defining the possible data flow among the developed sub systems. These data flow among the sub systems are mainly defined with help of DFDs. The level based requirements of the data flow among the sub systems of EM system to ABC University are mainly defined with the development of DFDs. The requirements of data flow to EM system are mainly identified with the DFD of 0- level. The implementations of data structure to this EM system are mainly identified with EM system’s DFD of 0 levels. Abstract view of EM system based on the data flow can be defined through this DFD. The occurrences of input and obtained outputs to sub systems are also defined through this pictorial representation of DFD to ABC University. Allowing the easy monitoring to administrator for handling the data flow makes DFD as the essential requirement for EM system development to ABC University. DF diagram (0-level) showing implementation of EM system for ABC University is provided in pictorial form:
