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.

  • 2016-12-15: Ups, things got a bit mixed-up in the exercise sheet: Exercise 3 should refer to the ether from Exercise 2 (not 1).
  • 2016-12-15: There is a new errata file, thanks for pointing out the mistake.
  • 2016-12-08: Mind the late change to Slide 14 of today's lecture - the atr-mapping for signals carries over from S_0 to S (thanks for pointing that out)
  • 2016-12-08: Please submit as teams in ILIAS to make submission management a bit easier for us - later this day there will be a post in the ILIAS forum with more information on how to submit as a team.

  • 2016-11-24: All exchange students which need an exam earlier than the regular date (see below), please contact me soon enough such that we can negotiate a date/time for an oral exam.
  • 2016-11-24: The candidate date for the regular exam (which will be a written exam) is Friday, 17.2.2017.
  • 2016-11-10: Register for access to the Rhapsody modelling tool on the host archithor - cf. ILIAS forum for more information.
  • 2016-10-20: Exercise Sheet 1 updated - two mistakes creeped into the earlier version: regular submission is (of course) before the tutorial, i.e. Tue, 8:00, and in Exercise 2 we want to have an attribute 't' of type Exercise*.

Formalia

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").

Exam

The kind of exam (oral or written) depends on the number of candidates: many candidates/written, few candidates/oral.

  • Kind, date/time, location:
  • Written Exam
  • Friday, February, 17th, 2017
  • 10:00 c.t., 90 minutes (please be there at 10:00 s.t.)
  • HS 101-0-026
  • permitted exam aids: one sheet of A4 paper (at most 200g/m^3) with handwritten notes on front and back
  • Erasmus students (and only Erasmus students): we can arrange individual dates / times for a (then oral) exam if necessary - please contact us appropriately soon.

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

Resources

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.
