  1. 16. Scalable Persisting and Querying of Streaming Data by Utilizing a NoSQL Data Store

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Khalid Mahmood; [2014]
    Nyckelord :;

    Sammanfattning : Relational databases provide technology for scalable queries over persistent data. In many application scenarios a problem with conventional relational database technology is that loading large data logs produced at high rates into a database management system (DBMS) may not be fast enough, because of the high cost of indexing and converting data during loading.
