Optimizing Aggregate Query Processing in Cloud Data

Sep 02, 2014· Existing aggregate query processing algorithms focus on optimizing various query operations but give less importance to communication cost overhead (Two-phase algorithm). However, in cloud architectures, the communication cost overhead is an important factor in query processing.

aggregate query processing in peer to peer networks

database query processing scheme is proposed to limit the search space of the given query by a domain based query routing mechanism which limits the search to related peers. A database query processing model in peer-to-peer networks was designed using top-k query processing technique and implemented using Java, and MySql.

Deciding equivalences among conjunctive aggregate queries

Apr 01, 2007· Equivalence of aggregate queries is investigated for the class of conjunctive queries with comparisons and the aggregate operators count, count-distinct, min, max, and sum. Essentially, this class contains unnested SQL queries with the above aggregate operators, with a where clause consisting of a conjunction of comparisons, and without a

The problem of answering large-scale ad hoc analysis queries, for example, range aggregate queries on data cubes possesses unique challenges. Exact solutions can be time consuming and difficult to implement, given the distributed and dynamic nature of P2P data cubes. In this
