Optimizing Aggregate Query Processing in Cloud Data
aggregate query operations. Along with that knowledge, we propose our storage structures, which will not only optimize query operations, but also communica-tion cost overhead caused in cloud data warehouses. Some of the earlier papers, which optimize aggregate query processing
Aggregate Query Processing Definition
Clustering spatial networks for aggregate query processing: . in the original problem definition given in Section 2.1.3, the number K of parts is not known in advance. Thus, they use a partitioning algorithm based on RB with ratio-cut heuristic in order to create a number of parts, each with a size less than or equal to the disk page size .
Oracle Database In-Memory: In-Memory Aggregation
Data Set Size, Concurrent Users and Query Complexity The size of the data set, query complexity and number of concurrent users (as well as other factors such as hardware, server configuration, etc.) all affect query performance. All other things being equal, IMA plans will scale better than non-IMA plans for query complexity and number of
Aggregate Query Answering under Uncertain Schema Mappings
correct and efficient processing of the data. Also, we focus on the analysis of aggregate queries over a single table, to avoid mixing issues with joins over uncertain schema mappings. Our analysis tests the effect of executing an aggregate query over a single table or a table that is the result of any SPJ query
Optimizing Aggregation Oracle Help Center
A typical analytic query aggregates from a fact table, and joins it to dimension tables. This type of query scans a large volume of data, with optional filtering, and performs a GROUP BY of between 1 and 40 columns. The first aggregation on the fact table processes the most rows.
Querying Dimensional Objects Using SQL
Nonetheless, you may want to aggregate products over color or size, or customers by age, zip code, or population density. This is the situation when you can use a GROUP BY clause when querying a cube. Your query can extract data from the cube, then use SQL to aggregate by attribute value.
A Grid Framework for Approximate Aggregate Query
query processing issue and propose the definition of a query layer that improves the capabilities of a generic sensor network, and define a de-clarative language for efficiently in-network query processing. Schlesinger et al. in [12] combine the Grid framework with sensor data-base systems. A query to the system is sent to one of the Grid nodes,
