Open Theses and HiWi Positions

There are various open topics for bachelor's theses, master's theses, guided research, or HiWi positions. All topics require good knowledge of data structure design and fluent programming skills in C++.

All topics are to be conducted within the "hierarchies" project. This project is a collaboration of SAP and our chair and aims at introducing support of hierarchical data into the relational in-memory database systems HyPer and SAP HANA DB. Therefore, theses can also be conducted at SAP in Walldorf and students have the opportunity to get an insight into a commercial state-of-the-art database system.

Topics are available in the following areas:
  • Efficient indexing of hierarchical data
  • Introduction of hierarchy query support into an in-memory database system
  • Query languages for relational and hierarchical data (SQL,XPath,...)
  • Data models joining hierarchical and relational data
  • Query plans for hierarchical data
  • Efficient B-Tree indexes for integer keys

  • x86 intrinsics cheat sheet v2.2: A cheat sheet containing most x86 intrinsics, like SSE and AVX intrinsics, grouped in an intuitive fashion. Due to the large amount of existing intrinsics, the sheet is rather big and thus best printed in DIN-A1 or DIN-A0 format. Suppose various mistakes as this is a very early version. Let me know if you find any.
