Prof. Dr. Felix Naumann

Information Integration

Information integration is the merging of heterogeneous information from various data sources to a homogenous, clean dataset. This lecture introduces this ever-important topic. It will cover the basic technologies, such as distributed database architectures, techniques for virtual and materialized integration, and data cleansing technologies.

Further Information:

  • Lectures can be given in English, on demand.
  • Slides will be made available on the HPI-internal materials-folder.
  • The lectures will be recorded by tele-task.
  • The exercises are led by Tim Repke.


The course will take place Mondays in F-E.06 and Thursdays in H-2.57 at 09:15 AM. Some lectures will have the form of exercises.
