    • Join-queries between two spatial datasets indexed by a single R*-tree 

      Vassilakopoulos, M.; Corral, A.; Karanikolas, N. N. (2011)
      A spatial join, a common query in Spatial Databases and Geographical Information Systems (GIS), consists in testing every possible pair of data elements belonging to two spatial datasets against a spatial predicate. This ...
    • Parallel processing of spatial batch-queries using xBR + -trees in solid-state drives 

      Roumelis G., Velentzas P., Vassilakopoulos M., Corral A., Fevgas A., Manolopoulos Y. (2020)
      Efficient query processing in spatial databases is of vital importance for numerous modern applications. In most cases, such processing is accomplished by taking advantage of spatial indexes. The xBR +-tree is an index for ...
    • Predictive intelligence in analytics aggregation of partial ordered subsets 

      Kolomvatsos K., Hadjiefthymiades S. (2020)
      Nowadays, the increased amount of users' devices produce huge volumes of data that should be efficiently managed by modern applications. Streams are adopted to deliver data that, usually, are stored into a number of ...
