  • RDF DATA WAREHOUSE VIA PARTITIONING AND REPLICATION
    Publication number: 20140156587
    Abstract: Hardware and/or software suitable for RDF data warehousing, a type of data integration wherein integrated information is represented as RDF and loaded into a centralized RDF database, is presented. Pieces of hardware/software suitably support desired performance and flexibility by transforming one or more RDF documents to a binary format where RDF resources are replaced by identifiers, indexing each integrated data source into a separate RDF database and finally merging data to a warehouse through merging steps. The RDF data warehousing is a special type of data integration approach that allows query optimization.
