Teaching period(s) Semester 1
Offered by School of Computer Science
Available as a free choice unit? Yes


This course unit discusses formalisms to capture, describe, transform and query semi-structured data (in particular XML, different schema languages, XQuery, etc.), and looks at their respective strengths and weakness. It will provide students with the background and skills to work with these and similar formalisms and tools, and with the understanding of relevant features to analyze their strengths and weaknesses.


This course unit aims to give students a good understanding of the core concepts of data modelling, and will give them some familiarity with various formalisms, APIs, and languages that have been developed for modelling data on the web, as well as various design and representation issues that arise. Students will learn how to compare different data modelling formalisms, and how to design or analyse a data management system, i.e., whether it makes good use of the features provided by the formalisms used, and whether it fits its purpose.

Laboratory sessions will ground the abstract notions on practical cases and tools.

Learning outcomes

Learning outcomes are detailed on the COMP60411 course unit syllabus page on the School of Computer Science's website for current students.
