MIS605 - Systems Analysis and Design - Management Assignment Help

Assignment Task

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.  

Task 1.  
Create and document a Context Diagram for the System.  
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.  
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.  
Task 4. 
Using your own experience with similar online student enrolment systems and the  information provided in the case study: 
(i) Identify all the entities and their relationships in the System 
(ii) 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? 

Should data be stored in files in a file system or in a database for the System? Justify your  answer.  
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).  
4. 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 2500 words.

Please provide all your answers in a MS word document.  
All diagrams must be drawn using Lucidchart and copied into the MSWord 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. 
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.
Subject Learning Outcome:  
a) Identify, critically evaluate and recommend information systems solutions for inefficiencies in business processes, procedures and work practices using data and process modelling techniques. 
Create and document a Context Diagram for the System. 
Use of correct notions. 
Include all major entities. 
Label arrows with data. 
Use verbs for data label. 
Appropriate use of arrows. 
The diagram clearly shows the interaction of the system with its external entities. 
Subject Learning Outcome:  
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. 
Create and document a Level 0 Data Flow Diagram (DFD). 
Level 0 DFD contain all the major high-level processes of the System and clearly outlines how these processes are interrelated. 
Level 0 DFD is balanced with the context diagram. 
Label arrows with data

Use verbs for the data label. 
Appropriate use of arrows. 
Clearly outlines all major processes and data storage critical to the System.

Select three major and non-trivial processes from Level 0 DFD, decompose each of the processes into  a more explicit Level 1 DFD. 
Level 1 DFD is balanced with the corresponding processes in level 0 DFD. 
Label arrows with data. 
Use of appropriate verbs for the data label.  
Appropriate use of arrows.  
Identified all the major processes and data storage critical to the System.
