Database systems form the heart of virtually any enterprise application. They manage vast amounts of data, yet allow for fast and efficient search; they handle thousands of updates every second, yet won't trip over problems due to concurrency; and guarantee consistency and data integrity even in the case of catastrophic events (loss of hardware, etc.).

In this course we learn how database systems can provide this service and performance. We will look “under the hoods” and understand how a database is built internally. We will get to see techniques that allow to construct a system in a scalable and robust manner.

More specifically, our agenda includes: space management (buffer manager), index structures (single- and multi-dimensional), query processing (e.g., external sorting, join processing), query optimization, concurrency control (e.g., two-phase locking), failure tolerance (ARIES), distributed database systems.

Exam Dates

There will be a 90-minute exam for this course (two chances to participate).

  • Friday, July 24, 2020; 18:00h-19:30h; Room Audimax and M/E 28
  • Tuesday, September 29, 2020; 09:00-10:30h; Room EF50/HS1 and

Allowed material for the exam: one piece of DIN A4 paper, hand-written (both sides, if you want); pocket calculator.

The situation around the corona virus has made the upcoming summer semester an immense challenge, for teachers as well as for students. Our department is investing huge efforts to turn our course offerings into an online format.

At this point, corona-related restrictions are officially in place until April 19, 2020. However, it is to be expected that there are serious disruptions even beyond that date. No reliable predictions can be made at this time, though.

The course “Architecture & Implementation of DBMS” will be turned into an all-online format. But please be prepared that the situation might change at any time; please bear with us.

  • Lectures will take place during the usual lecture hours (see above), but in the form of an online meeting (most likely Cisco Webex or Zoom). You will be able to attend the presentation live; and you can–and should–answer questions live.
  • Exercise groups will be done in a similar form, as online meetings. Since we plan to do many practical exercises this semester, meetings will be real “hands-on meetings”, not in presentation style.

There are many open questions, still; especially when it comes to tooling. Please bear with us! To ease the communication with our students, throughout the department we will ask all students to register for their respective courses. Information about that will be sent out (by the department) shortly (in the case of “Architecture & Implementation of DBMS,” registration will be handled via Moodle).
