Aggregation is a very common operation. For instance, the follow- Hierarchical Aggregation in Networked Data Management 363 Fig. 2. Query Processing Steps in NPDM ing SQL query in Figure 3 (from the TPC-H performance benchmark [18]) computes the sales of each brand per month: SELECT p_...
Additionally in this paper, we make the Ag-tree more complete by sorting the entries in each of the nodes. The final index structure proposed in this study is called an Ag+-tree. 展开 关键词: Range-aggregate query Multi-dimensional index Range query Aggregation operation ...

A method for use with an information retrieval system, in which the method is used for transforming a database statement containing a first subquery and a second subquery joined together, the first subquery including a group by operation over a child subquery, the method comprising removing the ...
The group-by and aggregation are fundamental but time-consuming operations for a DBMS. Using hash tables is a common approach to perform a grouping. In this paper, we study how to utilize the heterogeneous CPU-GPU platform to accelerate the group-by and aggregation based on the chained ...
