Mapping to Focus Areas

Below, you find the module's mapping to the study program's focus areas. This is done as a contribution to all relevant focus areas (in ECTS, and content-wise). This is also relevant for setting the module in relation to other modules, and tells to what extent the module might be part of other study programs.

Focus Area ECTS (prop.) Module Contribution to Focus Area
Generating and Accessing Knowledge 3

Students learn to handle problems in the area of database systems independently and to develop comprehensive solutions while applying and deepening the theoretical knowledge.

Architecting and Coding Software 2

Students learn to deal with NoSQL database systems and multimedia database systems as a particular type of object-related database systems

Acting Responsibly 1

Students learn about ethical aspects of Big Data in business environments.

Learning Outcome

After a successful completion of this module, students are able to …

  • handle problems in the area of database systems independently,

by (for new database systems:)

  • understanding the special opportunities and problems of when to store, analyse and tread Big Data efficiently, and
  • learning basic principles of NoSQL-Data models and –systems and other Big Data solutions, and
  • knowing particular requirements of database systems in the context of mobile applications and the appropriate solution strategies, and
  • appreciating the capabilities and difficulties of “in memory” database systems (DBS-RAM) as well as the cloud databases, and
  • developing an understanding of the ethical borders of „Big Data“.

(for multimedia database systems:)

  • developing an understanding of the special issues associated with storing and retrieving multimedia data, and
  • getting to know the SQL2011 standard in this field and acquire practical skills to build text, image, video and sound databases.

so that they are able to develop comprehensive solutions while applying and deepening the theoretical knowledge.

Module Content

The challenge of Big Data

  • Definition, possibilities and problems
  • Overview of the diversity of ‘Big-Data’-DBS
