Databases and Hardware: The Beginning and Sequel of a Beautiful Friendship
Graph Chatbot
Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
This thesis demonstrates that, despite earlier projections to the contrary, database replication on a cluster of low-cost commodity servers can transparently scale database performance. In a replicated system providing the standard transactional properties ...
Magnetic nanostructures have long been in the focus of intense research in the magnetic storage industry. For data storage the nonvolatility of magnetic states is of utmost relevance. As information technology generates the need for higher and higher data- ...
In stand-alone databases, the functions of ordering the transaction commits and making the effects of transactions durable are performed in one single action, namely the writing of the commit record to disk. For efficiency many of these writes are grouped ...
BEST PAPER AWARDWe present a memory-aware load balancing (MALB) technique to dispatch transactions to replicas in a replicated database. Our MALB algorithm exploits knowledge of the working sets of transactions to ...
The main objective of this paper is to present a flexible annotation management framework for a multimedia database system, applied to meeting recordings. Presented research and development activities are carried out within the scope of the IM2 project in ...
Many new applications, for example Wikis, social networks, and distributed recommender systems, require the efficient integration of decentralized and heterogenous data sources at a large scale. In this paper, we present our vision of a universal storage f ...
For further miniaturization of magnetic data storage devices, instruments for exploring magnetic nanostructures are needed. Hall sensors provide a non invasive technique for quantitative magnetic field detection. In contrast to the highly sensitive semicon ...
Current cluster architectures provide the ideal environment to run federations of main-memory database systems (FMMDBs). In FMMDBs, data resides in the main memory of the federation servers. FMMDBs significantly improve performance by avoiding I/O during t ...

With the deeply-ingrained notion that disks can efficiently access only one dimensional data, current approaches for mapping multidimensional data to disk blocks either allow efficient accesses in only one dimension, trading off the efficiency of accesses ...
