Lecture "Distributed Database Systems" WS 2010 / 2011
Lecture "Distributed Database Systems"
Dr. Katja Hose
PD Dr.-Ing. Ralf Schenkel
In today's data management, we face the problem that data is often naturally distributed among multiple sites. The distributed architecture requires sophisticated techniques to answer queries efficiently.
Beginning with the basics of data management in classical distributed database systems, this lecture gives an overview of the state of the art. More specifically, the lecture covers topics such as data fragmentation, replication, schema integration, query processing algorithms in general as well as for specialized architectures, e.g., standard distributed database systems, peer-to-peer systems, and grid systems.
Re-exams will take place on: April 11, 2011.
If you are interested, please contact Katja Hose to make an appointment.
- Lecture: Thursday, 14:15 - 15:45, room 0.01, building E1.7 (MMCI building)
- First lecture: Thursday, October 21
- Exercises: Monday, 14:15 - 15:45, room 0.01, building E1.7 (MMCI building)
- First excercise group: November 8
- No lecture on November 11 but the next assignment will be available online
- No assignment on December 2, no excercise group on December 13.
- Here is the final schedule for the oral exam. All exams take place in room 3.01, building E1.7 (when leaving the elevator, turn right and go through the glass door, the room is on the far right).
- The oral exam covers all topics considered in the lecture and in the exercise group up to and including February 3 (Grids and distributed top-k).
- Certificates (Scheine) can be picked up in building E1 4 room 402
Students planning to attend the course should have basic knowledge of standard database technologies (successful participation in the basic course on Database Systems or Information Systems is fine), even though we will introduce all necessary concepts and techniques in the lecture.
