AGiDS: A Grid-Based Strategy for Distributed Skyline Query Processing [chapter]

João B. Rocha-Junior, Akrivi Vlachou, Christos Doulkeridis, Kjetil Nørvåg
2009 Lecture Notes in Computer Science  
In this paper, we propose AGiDS, a framework for efficient skyline processing over distributed data.  ...  AGiDS consists of two phases to compute the result: in the first phase the querying server gathers the grid-based summary, whereas in the second phase a skyline request is sent only to the servers that  ...  In this paper, we presented AGiDS, a skyline query processing algorithm for distributed environments. AGiDS processes skyline queries efficiently by applying a two phase approach.  ...

Efficient execution plans for distributed skyline query processing

2011 Proceedings of the 14th International Conference on Extending Database Technology - EDBT/ICDT '11  
To address this trade-off, we introduce a novel framework, called SkyPlan, for processing distributed skyline queries that generates execution plans aiming at optimizing the performance of query processing  ...  In this paper, we study the generation of efficient execution plans for skyline query processing in large-scale distributed environments.  ...  Furthermore, SkyPlan uses MBRs for data summarization in contrast to AGiDS [16] that uses a grid-based data summary.  ...
