CiteSeerX — Aggregate Queries in Peer-to-Peer OLAP

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): A peer-to-peer (P2P) data management system consists essentially of a network of peer systems, each maintaining full autonomy over its own data resources. Data exchange between peers occurs when one of them, in the role of a local peer, needs data available in other nodes, denoted the acquaintances of the local peer.Approximate Aggregations in Structured P2P Networks,In corporate networks, daily business data are generated in gigabytes or even terabytes. It is costly to process aggregate queries in those systems. In this paper, we propose PACA, a probably approximately correct aggregate query processing scheme, for answering aggregate queries in structured Peer-to-Peer (P2P) network.

RPK-table based efficient algorithm for join-aggregate,

Join-aggregate query which returns aggregate information on the join of several tables is widely used in big data analysis. For instance, many TPC-H 1 queries contain joinaggregate operation for performance evaluation.

Robust and efficient aggregate query processing in peer-to,

The ability to approximately answer aggregation queries accurately and efficiently is of great benefit for decision support and data mining tools. A P2P network consists of numerous peer nodes that share data and resources with other peers on an equal basis. Unlike traditional client-server models, no central coordination exists in a P2P system; thus, there is no central point of failure.

Optimizing Aggregate Query Processing in Cloud Data,

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.Optimized Query Processing for Wireless Sensor Networks,periodic sampling, communication and query routing cost. In [12] proposed a peer to peer query processing model via peer to peer tree structure that query can appear in each node (against other models that query appear only in base station). In [2] proposed LMGANC algorithm that permit grouping aggregation for decreasing energy consumption.Abstract Approximating Aggregation Queries in Peer-to-Peer,,Abstract Approximating Aggregation Queries in Peer-to-Peer Networks Benjamin Arai UC Riverside [email protected],[email protected] Vana Kalogeraki UC Riverside [email protected] Abstract Peer-to-peer databases are becoming prevalent on the Internet for distribution and sharing of documents,Approximate Query Processing: Fortunately, it,

ABSTRACT

ABSTRACT Top-k query processing is a widespread field of research. Its application can be used in many fields like wireless sensor networks, mobile ad-hoc networks, peer-to-peer networks and many more. The basic problem in top-k query processing is that, a single algorithm cannot be used as aDBEst : revisiting approximate query processing engines,,In the era of big data, computing exact answers to analytical queries becomes prohibitively expensive. This greatly increases the value of approaches that can compute efficiently approximate, but highly-accurate, answers to analytical queries. Alas, the state of the art still suffers from many shortcomings: Errors are still high, unless large memory investments are made.CiteSeerX — Citation Query Mobihide: A mobile peer-to-peer,,Then, to improve system scalability of processing continuous privacy-aware queries, we propose a shared execution paradigm that shares query processing among a large number of continuous queries. The proposed scalable paradigm can be tuned through two parameters to trade off between system scalability and answer optimality.

Scalable Distributed Aggregate Computations through,

Abstract. Computing aggregates over distributed data sets constitutes an interesting class of distributed queries. Recent advances in peer-to-peer discovery of data sources and query processing techniques have made such queries feasible and potentially more frequent. The concurrent execution ofE–cient Range and Join Query Processing in Massively,,E–cient Range and Join Query Processing in Massively Distributed Peer-to-Peer Networks by Qiang Wang A thesis presented to the University of Waterloo in fulflllment of the thesis requirement for the degree of Doctor of Philosophy in Computer Science Waterloo, Ontario,Peer Review Examples - F1000Research,The authors rightly argue that “peer-review” is where the publication metaphor leads us, but it may be a false path. They overstate some difficulties of peer-review (No-one looks at every data value? No, they use statistics, visualization, and other techniques.) while not fully considering who is responsible for what.

Skyline-based Peer-to-Peer Top-k Query Processing

a super-peer is responsible for gathering all necessary data from its associated peers, in order to be able to answer top-k queries. For a maximum value of K, denoting an upper bound on the number of results requested by any top-k query (k ≤ K)1, each peer computes its K-skyband [8] as a pre-processing step. Then, super-peers aggregate theK,SIL: Modeling and measuring scalable peer-to-peer search,,Abstract The popularity of peer-to-peer search networks continues to grow,,search networks take advantage of the large aggregate processing power of many hosts,,be searched for this query.
