The goal of the research seminar is to teach the students the basics of scientific research and a basic knowledge of the inner mechanics of in-memory databases. The seminar is focused on recent research topics as well as latest hardware trends (e.g., non-volatile memory, 240 core server machines, co-processing) in conjunction with columnar in-memory database systems. Each student will work individually on a topic, resulting in a final paper (8-10 pages, IEEE) in addition to a midterm and final presentation. The topics vary from optimized (e.g., lock-free) data structures for in-memory database to general database concepts (e.g., transaction handling, memory tiering, co-processing). Each topic will have an implementation component, which should be employed and closely evaluated in the resulting paper.
