MIS300 - Systems Analysis and Design Assignment

Assignment Task

Task Summary

For this assignment, students need to individually write a 1500-word business report in response to the case study provided by your lecturer. There are two components:

1. Conceptual questions about the tasks business analysts undertake to support the systems analysis and design process

2. Practical questions in response to the case study provided by your lecturer.

Please refer to the Task Instructions for details on how to complete this task.

Context

Process and data modelling form a key part of systems analysis and design. It naturally follows business requirements elicitation and analysis, and is part of the next phase of systems design. It ensures that a model is created of how the system will convert data into valuable information for the organisation.

Context diagrams will help define the boundaries of the system being designed, data flow diagrams will show the flow of data through the system and entity relationship diagrams define the relationships between the different entities which are in scope for the system being built.

This is a continuation of the analysis and design process initiated in Assessment 1 with requirements analysis and will use the same case study.

To complete this task, you must:

1. Carefully review the case study provided to you by your lecturer.

2. Review your subject notes, essential readings and learning activities to ensure that you are well prepared for the assignment.

3. Create a report plan and identify all the key components required in your report.

4. Follow the outlined report structure Note: The report is brief and therefore will not require an executive summary or abstract.

Introduction

This serves as your statement of purpose for the report. You will tell the reader what you are going to cover in your report. You will need to inform the reader about:

• your area of research and its context 
• the key concepts you will be addressing
• what the reader can expect to find in the body of the report.

Body of the report

Conceptual questions:

• What is a context diagram and why is it required?
• What is a data flow diagram?
• What is an entity relationship diagram and what purpose does it serve?
• What are the differences between a data flow diagram and an entity relationship diagram?

Practical tasks

• Build a context diagram for the system using Lucidchart or any other diagramming app, such as app.diagrams.net.
• Create a level 0 data flow diagram (DFD) which includes the high-level processes of the system and their relationships. 
• Decompose 2 number of processes from the level 0 DFD into more detailed level 1 DFD processes.
• Identify the entities and their relationships in the system and document these relationships in an entity relationship diagram for the system.
• Convert the entity relationship diagram into a relational database design, including database tables and their relationships to the third normal form.
