Semester 2, 2018
Assignment 2 (35%), Due on 19th of October 2018
Assignments 2 is related to the Weekly activities from week 5 to Week 11. You must add all these activities to one document and submit it by the 19th of October 2018.
Read the Rubric for Assessment Task 2 from Leo (Very Important)
Rubric: Has 5 Criteria. C1: 15 marks, C2: 15 marks, C3: 10 marks, C4: 10 marks and C5: 5 marks.
Project due: on or before 19/10/2018 09:00 pm
Report: Read the Activity Sections Week by Week:
The purpose of the report is to demonstrate the theoretical understanding of fundamental concepts of Systems Analysis and Design through reflection. Your reflection should capture critical learning points that occurred during weeks 5-11. It should show that these learning points are well analysed, deeply reflected on, and comprehensively captured via discussion forums and practical activities.
How will the modelling diagrams be assessed?
a) Must use the diagram’s symbols provided in Leo:
Useful Links for Diagram Symbols (Assignment 2)
b) All the diagrams below (5 diagrams) have some relationship among them. This consistency and continuity should reflect in all the diagram.
Week 5:
Think about a large food fair with food stalls selling different type of food and drinks. Your task is to create a data flow diagram for this scenario. Use DIA software. (Diagram 1)
Steps to create a data flow diagram:
a) Think about basic or main activities that take place at a lemonade stall. List them.
b) Also think about the additional activities needed to support the basic activities. Add them to the list created at (b).
c) Group the activities in (b) in some logical fashion, possibly functional areas.
d) Use correct symbols to draw Context Level DFD.
e) Identify manageable sub- processes and draw Level 0 DFD.
Important points:
a) Use correct symbols and name elements in DFD correctly.
g) Study and understand the purpose of Context Level DFD and Level 0 DFD diagrams prior to drawing them.
Week 6:
The objective of this week’s practical activity is to understand the essentials of systems design using the running case study Sandra Medical Devices.
Answer the questions related to the systems design of Sandra Medical Devices.
Week 7
Note: Use your own words to answer the following questions. There is no point of typing what is in the textbook.
a) Scenario – a customer wants to buy a car. Using your own words, describe how object-oriented systems design can be applied to this scenario.
b) An object-oriented program consists of many objects. List all the objects that can have in this scenario. Draw a diagram as described below. (Diagram 2)
Refer to OO Program flow diagram on page 11 in SAD OOD Part 1 power point file.
c) Within each object, the program logic exists, in small segments called methods. These methods are invoked using messages. Select two objects in the scenario and draw design class diagram (Diagram 3) for each object. An example is shown below.
Refer to Design model class diagram on page 16 in SAD OOD Part 1 power point file.
Week 8:
The following figure (Figure 13-32 – page 436 of 7th edition, Figure 11-26 – page 363 of 6th edition) is an activity diagram for the scenario – Return books in the university library system. Apply object oriented design for this scenario.
a) An object-oriented program consists of many objects. List all possible objects for this scenario.
b) Develop a domain class diagram.
c) Then develop a design class diagram based on the domain class diagram created at (b). (Diagram 4)
d) Develop a communication diagram for this design. (Diagram 5)

Week 9:
Refer to the case study Computing Publishing Inc (CPI) in your textbook.
6th edition – page 405
7th edition – page 289
a) Consider the contents of this textbook as a template for CPI’s database content. Draw a class diagram that represents the book and its key content elements. (Diagram 6)
b) Expand your diagram to include related product content, such as a set of PowerPoint slides, an electronic book formatted as a Web site or PDF file, and a Web based test bank.
Week 10:
You work in a parcel courier service company where packages will be picked up and delivered within Australia. You are in charge of implementation and deployment of a new system that is replacing a critical existing system that is in operation for 24 hours a day. In order to improve the efficiency of the current system, your team has been working on developing four new sub-systems.
a) Custom Account sub-system (such as Customer Account)
b) Pickup Request sub-system (such as Sales)
c) Package Delivery sub system (such as Order Fulfillment)
d) Routing and Scheduling sub system (such as Scheduling sub system)
The development of these individual sub systems has been accomplished and now you have come to the deployment stage. To minimize the risk, you plan to phase in deployment of new subsystems over a period of six weeks and operate both systems in parallel for at least three weeks beyond the last new subsystem deployment. Because there aren’t enough personnel to operate both systems, you plan to hire up to 30 temporary workers during the parallel operation period.
Discuss the following deployment activities. Note: Your discussion should be related to the scenario above.
a) Training users
b) Deployment order
c) Support activities
Week 11:
Read case study – Custom Load Trucking on page 360 (7th edition) and answer the questions.
And the Discussion Forums Reflection for weeks 5, 6, 8, 9 and 10
