184.705 Semistructured Data Canceled

2024S, VU, 2.0h, 3.0EC


  • Semester hours: 2.0
  • Credits: 3.0
  • Type: VU Lecture and Exercise
  • Format: Hybrid

Learning outcomes

After successful completion of the course, students are able to demonstrate a deep understanding of semi-structured data (details further below). First we give an overview of the most important facts



A few more facts so that you can plan your schedule:

  • In 2024W, we will be offering Semi-structured Data as a 6 ECTS version
  • In 2024W, we will also offer a mode for those of you who still need the 3 ECTS version
  • That is, in 2024W you will be able to complete a 6 ECTS or a 3 ECTS version of the course depending on what you need.

If you will finish your studies in 2024S and the missing opportunity to obtain a "Semi-structured Data" certificate is hindering youfrom that:  

  • Please send an email to <ssd@dbai.tuwien.ac.at> with the subject starting with "[ssd] needed for study completion: "
  • We will be able to offer some solution for that so that you have the opportunity to obtain the certificate for completion in 2024S!
  • Depending on the numbers approaching us, we will communicate what mode makes most sense for that.




Detailed Learning Outcomes

After successful completion of the course, students are able to...

  • explain the differences between semi-structured and structured data.
  • apply the XML-technologies cover by the lecture to concrete problem settings.
  • detect the limitations of XML-technologies in concrete problem setting.
  • explain the differences between the XML-Schema language discussed in the lecture.
  • explain the differences between the XML-Query languages discussed in the lecture.
  • explain the differences between the XML-APIs discussed in the lecture.

Subject of course

  • XML
  • XML schema languages (DTDs, XML Schema)
  • XML query languages (XPath, XQuery, XSLT)
  • XML-APIs (parsers, XSLT-processor)

Teaching methods

  • The lecture introduces XML and related standards and explains them using examples.
  • There are exercises that deepen the students' understanding of the concepts introduced in the lecture.
  • There will be question hours with the tutors spread over the time before the submission dates.
  • The exercise mainly consists of programming tasks and accounts for 25% of the overall grade.
  • In order to create the same prerequisites for submission for all students, there is a uniform submission date for all students followed by the submission interviews.
  • During the submission interviews, the examples are checked for correctness, but especially for understanding, and feedback is given accordingly.

 *********Hybrid Teaching in 2023S ************
Due to the COVID-19 crisis, this course will use a hybrid approach to teaching, using the TUWEL platform as well as meetings with the students on campus. Exercises will be managed using TUWEL, while the exercise discussions with tutors will be held online using Zoom. In addition, a discussion forum on TUWEL will be used to answer student questions and to clarify issues.

The exam mode: written exam in the university campus. 

In case of COVID-19 restrictions that disallow events on campus, the following changes would be made to the organization of the lecture:

- the Q&A would be moved to online mode (Zoom meetings)

- the examination mode would be changed to "Online written exam on paper". In this mode, the examiners and the students are permanently connected via  audio and video in a online meeting. At the end of the exam, the students must scan  of the written exam and upload it to TUWEL within the time specified by the examiner (approx. 5 minutes).
