Modelling object-oriented software – an introduction

1.2 The aims of this course

Starting with the requirements document for a hospital based system dealing with teams of doctors, patients and wards (see the 'View document' link at the foot of this page), the main aim of this course is to construct a conceptual model for that system. In drawing up this model, the course:

  • sets out some of the key activities and concepts that are involved in developing a conceptual model (Section 2.1);

  • introduces techniques for analysing the requirements document to identify conceptual classes and their attributes (Section 3.1);

  • outlines the different types of relationship that can exist between classes, and how to identify them (Sections Section 3.1 and Section 4.1);

  • describes how the model can include other kinds of information which is discovered from analysis, such as events and constraints (Section 5.1 and Section 6.1);

  • shows you how to identify information that can be derived from other information in the model

  • in the process of doing all the above, develops a conceptual model for the Hospital System

UML-like class and object diagrams will be used to help you develop and think about the conceptual model. These diagrams can be used to describe the software classes and objects that will eventually be implemented in code, but they can equally well be used for conceptual models that deal with entities from the system domain. The UML is flexible enough for both purposes.
