    Sammanfattning : I dagens samhälle är energieffektivisering en viktig parameter när man pratar om hållbar-het. Många fastigheter saknar tekniska lösningar för att effektivt övervaka och hantera en-ergiförbrukning. För att möta detta behov strävar företag som iquest efter att digitalisera och automatisera energiövervakning. LÄS MER

  3. 2. A performance comparison between graph databases : Degree project about the comparisonbetween Neo4j, GraphDB and OrientDB on different operations

    Kandidat-uppsats, Högskolan Kristianstad/Fakulteten för naturvetenskap

    Författare :Robert Alm; Lavdim Imeri; [2021]
    Nyckelord :GraphDB; OrientDB; Neo4j; Graph Databases; Profiling; Performance; Databases;

    Sammanfattning : In this research we study what is the theoretical complexity of Neo4J, OrientDB and GraphDB, (three known Graph Databases that can be accessed by a Java instance), and how this complexity is manifested in a real life performance, To study their practical performance, a software was implemented and named as a profiler, which is capable to profile, (to record the time that is needed), each operation, and display the results in an accurate and organized manner. The technical documentation of those 3 databases was reviewed as well, to identify how the databases work, and what are their strong and weak points. LÄS MER

  4. 3. Comparison of geospatial support in RDF stores: Evaluation for ICOS Carbon Portal metadata

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Sammanfattning : The evolution of World Wide Web (WWW) into semantic web is happening with the aid of standards like Resource Description Framework (RDF), SPARQL and a few others from World Wide Web Consortium (W3C). Over the years, semantic data management technologies have been introduced as software platforms commonly known as RDF stores. LÄS MER
