1. Introduction

State the purpose of the report.

2. Business Overview

Write up a brief overview of the company:

- Structure,

- Key Activities

- Problems,

- Gaps,

- Opportunities,

- Functional Decomposition

3. Analysis

- Current processes,

- Requirement Determination,

- DFD (Context, Level 0 and Level 10

- Logical Modelling (Decision Table Decision Tree .....)

- Data Modelling (ER Diagram)

- Class, Use Case, Activity and Sequence Diagrams)

4. Requirement Specification

- Functional and Non-Functional

5. Proposed Business Solution

- Forms, Reports, User Interface design

6. Project Feasibility

- Cost, Benefit, Risk Analysis

7. Implementation

- Options

8. Maintenance

- Maintenance Request

- Requests for Implementing Changes

9. Conclusions

- Recommend a key area for detailed analysis. Justify your suggestions.

10. Appendices

- If any

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), Use case and activity diagrams based on the case study described below. 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.
