El grup DAMA-UPC s'especialitza en la gestió de grans volums de dades amb especial èmfasi en el rendiment i la qualitat de les dades. Té en compte les necessitats del kernel de la base de dades, centrant-se especialment en l'optimitzador i el motor d'execució, o el repositori de dades bàsic ubicat per sobre del sistema de fitxers del SO. Les seves habilitats permeten la millora del rendiment en aplicacions executades amb les dades en memòria i en aplicacions executades amb les dades a disc.

DAMA-UPC és membre de la Xarxa IT pertanyent al Departament d'Industria de la Generalitat de Catalunya des del començament del 2005.

  • Marshall-Olkin extended Zipf distribution 

    Pérez Casany, Marta; Duarte López, Ariel; Prat Pérez, Arnau (Springer, 2015-12-18)
    Capítol de llibre
    Accés obert
    Being able to generate large synthetic graphs resembling those found in the real world, is of high importance for the design of new graph algorithms and benchmarks. In this paper, we first compare several probability models ...

  • Software trace cache 

    Ramírez Bellido, Alejandro; Larriba Pey, Josep; Valero Cortés, Mateo (2005-01)
    Article
    Accés obert
    We explore the use of compiler optimizations, which optimize the layout of instructions in memory. The target is to enable the code to make better use of the underlying hardware resources regardless of the specific details ...

    The massive amount of tourists, citizens and traffic in big cities usually collapse busy areas causing transport inefficiency, unbalanced economic growth, crime, and nuisance among citizens and visitors. Therefore, the ...
  • Put three and three together: Triangle-driven community detection 

    Prat Pérez, Arnau; Domínguez Sal, David; Brunat Blay, Josep Maria; Larriba Pey, Josep (Association for Computing Machinery (ACM), 2016-02-01)
    Article
    Accés obert
    Community detection has arisen as one of the most relevant topics in the field of graph data mining due to its applications in many fields such as biology, social networks, or network traffic analysis. Although the existing ...

    Sànchez-Marrè, Miquel; Gómez Villamor, Sergio; Teixidò, F; Gibert, Karina (2006-07)
    Report de recerca
    Accés obert
    Feature selection and feature weighting methods in supervised domains have been thoroughly discussed in the literature. On the other hand, very little work has been done for unsupervised domains, probably due to the assumed ...
