CiteSeerX — TECHNOLOGY Aggregate Query Processing using

CiteSeerX Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Peer-to-peer (P2P) network is increasingly becoming popular because it offers oppor¬tunities for real-time communication, ad-hoc collaboration and information sharing in a large-scale distributed environment. Peer-to-peer computing is defined as the sharing of computer resources and

Abstract Approximating Aggregation Queries in Peer-to-Peer

Abstract Peer-to-peer databases are becoming prevalent on the Internet for distribution and sharing of documents, applications, and other digital media. The problem of answering large scale, ad-hoc analysis queries e.g., aggregation queries on these databases poses unique challenges. Exact solutions can be time consuming and

CiteSeerX — Aggregate Queries in Peer-to-Peer OLAP

Abstract. 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.

First, we add a query processing layer to perform innetwork data aggregation over peer caches. Second, we introduce the concept of Query-Trails: a cache listing recent data requestors.

Abstract Computing aggregates over distributed data sets constitutes an interesting class of distributed que-ries. 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 of multiple and

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

Optimizing Aggregate Query Processing in Cloud Data

Sep 02, 2014 Abstract. In this paper, we study and optimize the aggregate query processing in a highly distributed Cloud Data Warehouse, where each database stores a subset of relational data in a star-schema. Existing aggregate query processing algorithms focus on optimizing various query operations but give less importance to communication cost overhead

Query Routing and Processing in Peer-To-Peer Data Sharing

Abstract. Sharing musical files via the Internet was the essential motivation of early P2P systems. Despite of the great success of the P2P file sharing systems, these systems support only "simple" queries. The focus in such systems is how to carry out an efficient query routing in order to find the nodes storing a desired file.

Cell Abstract Indices for Content-Based Approximate Query

Apr 14, 2004 Abstract. In this paper, cell abstract indices are presented to process content-based approximate queries in structured P2P data systems. It can be used to search as few peers as possible but get as many returns satisfying users’ queries as possible on the guarantee of high autonomy of peers.

Peer to Peer Networks an overview ScienceDirect Topics

In a peer-to-peer network, computers on the network are equal, with each workstation providing access to resources and data. This is a simple type of network where computers are able to communicate with one another and share what is on or attached to their computer with other users. It is also one of the easiest types of architectures to create

Communication-efficient preference top-k monitoring

With the increase of data generation in distributed fashions such as peer-to-peer systems and sensor networks, top-k query processing which returns only a small set of data that satisfies many users' preferences, becomes a substantial issue.When data are periodically updated in each epoch e.g., weather information, without any techniques, a naive solution is to aggregate

Aggregate aims to publish on a wide variety of topics that focus on the processes of aggregation of atoms, ions, molecules, oligomers, polymers, clusters, particles, gels, hybrids, composites, cells, pathogens, etc. in a broad range of areas such as chemistry, physics, materials, engineering, biology, life science and so forth. Aggregates often behave differently from, and

Improving Search in Peer-to-Peer Networks

network, nodes spend processing resources (i.e., cycles) to forward the query, process it, etc, and bandwidth to send and receive messages. The main cost of queries are there-fore bandwidth and processing. Since the cost of a query is not incurred at any single node in the network, it makes sense to discuss costs in aggregate (i.e., overall the

Fixed-Precision Approximate Continuous Aggregate Queries

In this paper, we outline our efficient sample- based approach to answer fixed-precision approximate continuous aggregate queries in peer-to-peer databases. We describe our approach in the context of Digest, a two-tier system we have developed for correct and efficient query answering by sampling. With Digest, at the top tier we develop a query evaluation

Designing a Super-Peer Network Stanford University

Abstract A super-peeris a node in a peer-to-peer network that operates both as a server to a set of clients, and as an equal in a network of super-peers. Super-peer networks strike a balance between the inherent efficiency of centralized search, and the autonomy, load balancing and robustness to attacks provided by distributed search.
