Software Design, Modelling, and Analysis in UML

The model-driven approach to software and systems development proposes to address quality and complexity issues in the development process. The usage of modelling languages not only for documentation, but, e.g., for automated analysis, test generation, and code generation is gaining momentum in particular in the context of (safety) critical software development. The necessary pre-requisites are a semantically founded modelling language and methods and tools for analysis. We will take the Unified Modelling Language (UML) as an example and demonstrate how to equip a relevant sublanguage (sometimes referred to as executable core) with a precise meaning in line with the official standard documents. To complement these discussions, we provide access to a contemporary UML modelling tool and use it for some of the exercises.

  • 2012-03-14: preliminary results of the written exam:
    1.0 1.3
     [88,78] (78,73]
     1 0

    Exam review ("Klausureinsicht") will be on Thu, March 22nd, 14:00 - 16:00
  • 2012-02-15: too bad, I forgot the advertisement block:
    • in Summer Semester 2012: Lecture Real-Time Systems
    • if you want to conduct a Master Team Project or your Master's thesis in areas related to the lecture (formal methods, defining formal semantics, designing an own DSL with syntax and semantics, etc.) feel free to contact me.
  • 2012-02-15: annotated slides of Lecture 20 have been updated to carry the new annotations from today
  • 2012-02-13: typo in exercise sheet 07: Figure 1 gives the state machine of C_0, not of C_3.
  • 2012-02-09: exercise sheet 07 updated (added note on substitution in bonus task)!  If the name is not exercise-20120209-2.pdf, then you have the old one.
  • 2012-02-01: Achtung: LSC slides from today are in the PDF of Lect. 17
  • 2012-01-18: for technical questions regarding Rhapsody, please approach Evis if you get stuck
  • 2012-01-18: the Rhapsody project in the lecture didn't work since we used a hollow diamond where we meant to use a filled diamond (composition) - the project available for download should have fixed this issue and sports two communicating objects.
  • 2012-01-16: exercise sheet 05 updated (submission dates were wrong)!  If the name is not exercise-20120116-1.pdf, then you have the old one.
  • 2011-12-07: exercise sheet 03 updated!  If the name is not exercise-20111207-1.pdf, you have the old one (with task 4 being about state machines).
  • 2011-12-07: mmh, seems that we have lost the best part of the audio recording before the break, and don't have any recording for after the break - which is a pity given the lively discussion
  • 2011-12-06: exam dates fixed - see below
  • 2011-11-21: lecture continues, lecturer no longer ill
  • 2011-11-14: Rhapsody access should be available - please try it out
  • 2011-11-09: for access to the Rhapsody tool (for exercise sheet 2) please mail your pool account name by Friday, 2011-11-11, 13:27 [just realised: 11:11 would have been a much funnier deadline time ;-)]
  • 2011-10-27: first recordings online
  • 2011-10-24: student position taken


Prerequisites for admission to the final exam, form of the final exam, and everything will be announced in the first lecture.

Admission criteria

50% of the total admission (or: good will) points in the exercises are sufficient for exam admission. (For example, perfect solutions to exercise sheets 1, 3, 5, and 7 and no solutions to 2, 4, and 6 would satisfy this requirement; so would 50% of the points in each exercise). 

Exercise Submission Scheme

The exercise sheets are online early in order to allow you to be aware of the tasks while following the lecture. There will be an early/regular submission scheme following a pattern to be announced.

Note: The exercises will be rated on two scales: admission points (given your knowledge before the tutorial, how sensible is your proposal; "good will rating", "upper bound") and exam points (given the additional knowledge from the comments on your proposal and the tutorial, how many points would your proposal at least be worth in a written exam; "evil rating", "lower bound").


For the students in the master program, there will be

  • a written exam of length 90 min. - unless the number of candidates drops below a certain threshold
  • date/time: Friday, 9.3.2012, 10:00
  • room: SR 101-01-009/13


For the students in the bachelor program, there will be

  • oral exams of length 30 min.
  • dates/times: Friday, 24.2.2012 - please ask for time slots at the examination office


Note: The module result (grade, "Note") is completely determined by the exam.


Slides, Exercises, and Recordings

Note: the following plan is tentative in the sense that the assignment of topics to dates is subject to change depending on the flow of the lecture. The assignment of form (lecture or tutorial) to dates is fixed. Slides will be typically only provided after the lecture.


Note: the TechSmith Screen Capture Codec seems to be necessary for playback of the recordings provided on the Electure portal.
