A Scalable Peer Data Management System

Project Members: Armin Roth, Felix Naumann (former members: Martin Schweigert, Tobias Hübner, Véronique Tietz, Matthias Weidlich, Fabian Garagnon)

System P is a full-fledged Peer Data Management System (PDMS) developed at Humboldt-Universität and the Hasso Plattner Institut. Its main feature are completeness-driven query optimization algorithms that allow it to scale to very large numbers of peers. The testbed of System P includes a powerful generator to create large PDMS instances according to a given set of parameters as well as a visualization component.

Implementation

  • System P and its test bed was implemented by Martin Schweigert, Tobias Hübner and Véronique Tietz as part of their thesis
    • Martin Schweigert: Entwurf eines Peer Data Management Systems mit Steuerungs- und Simulationskomponente
    • Tobias Hübner: Entwicklung einer Testumgebung für ein Peer Data Management System
    • Véronique Tietz: Parallelisierung der Anfragebearbeitung in einem Peer Data Management System

    Matthias Weidlich enriched the system by many new features.
