Dexter (Dresden Index for Transactional Access on Emerging Technologies)

Index structures are core components of typical database management systems. While this area has been studied for a long time, many aspects need to be reconsidered in the context of modern hardware architectures. The focus of DEXTER is to design an indexing system for main-memory data that exploits emerging technologies. DEXTER offers a well-balanced read/write performance that suits for high update rates and mixed workloads required for e.g., operational BI applicatiion.

The DEXTER project comprises the follwoing sub projects:



  • In-Memory Indexing:
