Clustering spatial networks for aggregate query processing ,Relational aggregate query processing techniques for real

In processing aggregate network queries, a vast amount of data must be iteratively accessed in such a way that records of connected junctions are likely to be concurrently accessed Consequently, the disk pages that contain these records must be fetched into the memory for processingIn this thesis, a new query processing technique is proposed to cut down systematically the time involved in processing aggregate relational algebra queries in relational databas The author uses data samples and statistical methods to construct an approximate response to a given aggregate query.

Evaluation of top-k OLAP queries using aggregate R-trees ,PostgreSQL: Documentation: 11: 920 Aggregate Functions

A straightforward method to evaluate a top-k OLAP query is to compute the aggregate value for each group and then select the groups with the highest aggregat In this paper, we study the integration of the top-k operator with the aggregate query processing moduleAggregate functions compute a single result from a set of input valu , Beware that this approach can fail if the outer query level contains additional processing, such as a join, because that might cause the subquery's output to be reordered before the aggregate is computed.
