Assignment Task :

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. 

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

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 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.
