Literature and Lectures

This page contains some useful tutorials for the astah UML editor, information about the text book including reading instructions, and recordings from all lectures.  

1. Astah Tutorial

There is a user's guide at http://astah.net/manual Links to an external site..

Videos that show how to create class and sequence diagrams using Astah:

2. Course Literature, A First Course in Object Oriented Development

The course text book, Lindbäck: A First Course in Object Oriented Development, exists only as a pdf which is available here, object-oriented-development.pdf Links to an external site..
The code examples from the book are included in this NetBeans project, https://github.com/oodbook/code/ Links to an external site.

3. Lecture Content and Reading Instructions

All lectures are recorded, there are no live lectures except the first. The lectures focus on explaining and giving examples, they do not cover all material. It is therefore not sufficient to just watch the videos, but instead necessary to also read the specified sections of  A First Course in Object Oriented Development

Preparation for Seminar 1

Lecture 1, Introduction, Mars 22 10.15-12

To read

Chapter two of A First Course in Object Oriented Development.

Recording

Here is the recorded zoom lecture, https://youtu.be/nIUP5oblktk Links to an external site.. The very first part where I introduce myself is missing, since I forgot to start the recording.

Jag vill poängtera två saker:

  1. Börja arbetet på en gång, seminarieuppgifterna är omfattande. Det är också nödvändigt att ha tittat på föreläsning 1-4 eller läst kapitel fyra i boken innan första övningen den 25/3.
  2. Detta ämne handlar i stor utsräckning om diskussion och utvärdering. Det finns många sätt att lösa en uppgift utan att göra direkta fel, och det är viktigt att utvärdera för- och nackdelar hos olika lösningar. Samarbeta därför helst om seminarieruppgifterna (rapporten är dock individuell).
