For Group Report, students are required to use Microsoft VISIO tools to design Context & DFD diagrams and Data Modelling Process.

Construct an Entity Relationship Diagram using Microsoft VISIO tools based on the case study described below. The ER model should include the following:

A brief description of the notation used in the model
A statement of all business rules adopted in the development of the diagram
A definition of all the entities
An English interpretation of all the relationships
The actual Entity Relationship Diagram showing all details (Modality, Cardinality, Primary and foreign Keys ... etc)
All many to many relationships must be resolved and should not appear on the diagram as many to many. Any one to one relationships used should be justified)
A List (at least 3) of the possible attribute associated with every entity identified.

Construct a Context Diagram, Function Decomposition & Data Flow Diagrams (Level 0 and level 1 only) based on the case study provided. There should be one level 0 diagram only, and for each function/process defined in the level 0 diagram, one level 1 diagram is required. (Might be pushing it to get a full set of level ones with the amount of information you have given them. You might consider asking for a couple of level 1 diagrams.)

All diagrams must be computer generated using VISIO tools and balanced in conformance to the rules and standards specified in lectures and tutorials.
