Skyline query processing in Spatial Hadoop

2014
Το MapReduce είναι ένα προγραμματιστικό μοντέλο που επιτρέπει την επεξεργασία μεγάλου όγκου δεδομένων σε ένα cluster από μηχανήματα. Ένα MapReduce job διαμοιράζει τα δεδομένα εισόδου σε ένα σύνολο από ανεξάρτητα κομμάτια τα οποία επεξεργάζονται από τις map διεργασίες παράλληλα.

Scalable Query Processing on Spatial Networks.

2008
Spatial networks (e.g., road networks) are general graphs with spatial information (e.g., latitude/longitude) information associated with the vertices and/or the edges of the graph. Techniques are presented for query processing on spatial networks that are based on the observed coherence between the spatial positions of the vertices and the shortest ...
