Systems Analysis and Design

Assessment - Design Specification

Learning Outcome 1: Identify, critically evaluate and recommend information systems solutions for inefficiencies in business processes, procedures and work practices using data and process modelling techniques.

Learning Outcome 2: Formulate, validate and document business requirements for a medium-scale information system development project and effectively communicate these requirements to the stakeholders.

Learning Outcome 3: Demonstrate the ability to effectively analyse, design and develop information systems using Unified Modelling Language (UML) models.

Task Summary

Based on your responses to questions in Assessment 1, perform process and data modelling and develop and document a number of design diagrams including context diagram, level 0 and level 1 data flow diagram and entity relationship diagram.

Context
In Assessment 1, you performed a comprehensive requirement analysis for the case study that was given to you. 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.

Process modelling and data modelling can be used to provide deeper understanding of a system thus they are an integral part of system analysis. Process modelling models processes in a system while data modelling helps in identifying the data that flows through the processes.

Instructions

1. Please read case study provided to you by your facilitator. Note that every piece of information provided in this case study has a purpose.

2. The solution that you provided in assessment 1 and the feedback of your Learning Facilitator against assessment 1 would also serve as an input to assessment 2.

3. Please answer the following questions:

Question 1
Create and provide a Context Diagram for the given case study.

Question 2
Create and provide a Level 0 Data Flow Diagram (DFD). The Level 0 DFD should contain all the major high-level processes of the System and should show how these processes are interrelated/interacting.

Question 3
Select three important processes from Level 0 DFD and provide their decomposition (Level 1 DFD).

Question 4
For the given case study, provide an Entity Relationship Diagram (ERD). Provide the logical model only!

Question 5
For the given case study, identify the data stores including the files that are not part of ERD.

Question 6
Translate the ERD you developed in Task 4 into a physical relational database design. Use some database tool such as Microsoft Access to create your database and submit diagram that you made using this tool. Normalise your database design to the Third Normal Form (3NF).

Word Count and Layout

The word count of this assessment is 2500 words +/- 10% but this assessment focuses largely on diagrams. The text in this assessment would largely be the explanation of the diagrams.

Referencing
It is essential that you use appropriate APA style for citing and referencing research.
