Abstract: The last decade has been characterized by radical changes in the computing landscape. We have witnessed the advent of multi-core processors, flash-based storage systems and the proliferation of scale out architectures, such as map-reduce-based systems and massively parallel databases. Although data management systems have embraced modern hardware technologies to some extent, they have not realized their full potential. The goal of this thesis is two-fold. Primarily, it demonstrates the staggering potential for performance improvement offered by modern hardware architectures and, then, proposes how data management systems must alter in order to realize this potential. Additionally, this thesis demonstrates that utilizing modern hardware architectures is important both for performance and energy-efficiency. Towards this goal, we propose query processing and indexing techniques for chip multiprocessors and we analyze the trade-offs of executing complex database queries on modern processor technologies. Subsequently, we propose query processing methods tailored to flash-based storage systems. Finally, we analyze the power consumption of database systems and we reveal opportunities for improving their energy efficiency.
