Learning Outcomes The Subject Learning Outcomes demonstrated by successful
completion of the task below include:
a) Identify, critically evaluate and recommend information
systems solutions for inefficiencies in business processes,
procedures and work practices using data and process
modelling techniques.
b) Formulate, validate and document business requirements
for a medium-scale information system development
project and effectively communicate these requirements to
the stakeholders.

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 given case study. 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 processes –
i.e. the sequence of activities that people do; while data modelling seeks to describe the data flows
MIS605_Assessment_2_Brief_Design Specification Page 1 of 5
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.
Instructions
1. Please read case study provided with assessment 1. Please note that every piece of information provided in this case study serves a purpose.
2. Please complete the following tasks: Task 1.
Create a Context Diagram for the given case study. (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 important processes from Level 0 DFD, decompose each of the processes into a more explicit Level 1 DFD.
(24 marks)
Task 4.
For the given case study, provide an Entity Relationship Diagram (ERD).
(20 marks)
MIS605_Assessment_2_Brief_Design Specification Page 2 of 5
Task 5.
For the given case study, identify the data stores including the files that are not part of ERD.
(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. Normalise your database design to the Third Normal Form (3NF).
(16 marks)
Please note that your responses to the tasks above must relate to the case study provided.
Word Count and Layout
The total word count for the written assessment should be no more than 2200 words. Please provide all your answers in a MS word document.
All diagrams must be drawn using any diagramming tool but the same should be copied to MS Word document.
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.
The recommended font size is 12 with 1.5 spacing.
Referencing
It is essential that you use appropriate APA style for citing and referencing if needed. Please see more information on referencing here http://library.laureate.net.au/research_skills/referencing
Submission Instructions
Please submit the written assessment via the Assessment link within Assessment 2. The Learning Facilitator will provide feedback via the Grade Centre in the LMS portal. Feedback can be viewed in My Grades.
