CSE1IS Information Systems
Assignment 1

Introduction

There are two parts to this assignment. You are to attempt both parts. Part 1 seeks to develop and test your understanding of what an information system is. Part 2 seeks to develop and test your understanding of, and skills at drawing, context and level 0 data flow diagrams.

Part 1 (5 + 3 marks)

You are to investigate an information system (IS) of your own choosing. For the IS:

1. Produce a diagram which shows the major components of the IS and how these components link together to form the IS. We developed a model of a generic IS in a lecture. Use this model as a template for your diagram. Make sure you include data capture, data input, data storage, data processing, output and attribution of meaning in your diagram.
2. For the IS give examples of raw data, validation of data, organised data, attribution of meaning, information, and decision making based on the information.

IMPORTANT: Before you begin your diagram you must check with your lecturer that the IS you have chosen is appropriate for this assignment.

Part 2 (3 + 4 marks)

Produce a context and a level 0 data flow diagram for the Bendigo Airport Bus Service (BABS) case study we have been studying in class. A systems analyst's notes from interviews with Rowena, Barry and Doug can be found here.
