    On distributed data processing in data grid architecture for a virtual repository
    (Wydawnictwo Politechniki Łódzkiej, 2010) Kuliberda, Kamil; Wiślicki, Jacek; Kowalski, Tomasz Marek; Adamus, Radosław; Kaczmarek, Krzysztof; Subieta, Kazimierz
    The article describes the problem of integration of distributed, heterogeneous and fragmented collections of data with application of the virtual repository and the data grid concept. The technology involves: wrappers enveloping external resources, a virtual network (based on the peer-topeer technology) responsible for integration of data into one global schema and a distributed index for speeding-up data retrieval. Authors present a method for obtaining data from heterogeneously structured external databases and then a procedure of integration the data to one, commonly available, global schema. The core of the described solution is based on the Stack-Based Query Language (SBQL) and virtual updatable SBQL views. The system transport and indexing layer is based on the P2P architecture.
