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.

News

  • 2013-01-08: Exercise Sheet 5, Figure 3(b) reads "n \rightarrow x".  It is supposed to be "n.x" (in our expression language OCL); it becomes something similar to "n->x" in C++ in Rhapsody.
  • 2012-12-04: exam date fixed
  • 2012-10-26: submission dates on exercise sheet fixed
  • 2012-10-26: recordings finally online, sorry for the delay

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

There will be

  • an oral exam of length 30 min.
  • date/time: 21.3.2013, 28.2.2013

 

Please contact the examination office for time slots.

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. 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.
