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 leve1 data flow diagram and entity relationship diagram.

Question

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

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.

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

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

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

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).
