Modelling object-oriented software – an introduction
How do you model a software system? This free course, Modelling object-oriented software an introduction, will help you to work through the processes necessary to produce a conceptual model, by analysing the requirements document to identify classes and associations appropriate for modelling the system domain, together with their respective attributes and multiplicities.
Course learning outcomes
After studying this course, you should be able to:
- list the components that make up a conceptual model of a system domain, and describe briefly the form and purpose of each component
- explain why a conceptual model forms the basis for modelling the structure of the system, i.e. gives an initial structural model of the system
- use various techniques and guidelines to identify an appropriate set of classes and associations from a requirements document, including their attributes and multiplicities
- identify situations where a generalisation relationship between classes exists, and decide on appropriate parent and child classes, and their attributes and associations.
- identify and reason about derived attributes and associations.
