SDM: Week 3

Topic: Models in the design process

(This is a week with lots of material! Don't worry, quieter weeks are coming. It's ok to get a little behind provided you're caught up by the lab assessment.)

Lectures

Models in the design process 1: conceptual modelling:

UML class diagrams, detail

  • Slides by Lethbridge and Langaniere cover many aspects of class diagrams and is a useful reference: you should read them all. They are a good reference for most of the UML class diagram notation you need to know, and in particular contain an introduction to OCL. I will not lecture to them, but Tim's own lectures are available on youtube. They go into a lot of detail - you'll see that there are four lectures over an hour long each on this chapter alone (and you'll find lectures on the other chapters of his book there too). You are not required to watch them, though you might like to. A quicker way to use them would be to jump into the section of any lecture that is about something you don't understand when you read the slides.

Models in the design process 2:

In the Q&A/discussion session we will discuss all the UML diagrams in this course, with time to ask questions and address some subtleties.

Readings

Technical UML stuff:

  • (After watching the OCL video) read Chapter 7 of the OCL2.4 standard but see here for some parts you can leave out.

By the time of next week's lab, you should be competent to read use case diagrams, and to read and write class, sequence, state and activity diagrams, and OCL. And that's all the UML we do in this course - now it's on to more interesting things...
