Situations in P2P data integration system
نویسندگان
چکیده
Situations can be used to model context of agents’ actions in heterogeneous P2P data integration system. They are the crucial concept in the situation theory and are suitable to cope with data, metadata, information partiality, open-world and non-monotonic reasoning in knowledgebase systems. In the SIXP2P system agents can ask and answer queries, which are propagated to their partners and are evaluated with respect to partners’ contexts. These actions are done via Prolog-like goals. Operational semantics of the computations is presented as a set of context-dependent rules. Specification of sample actions is depicted.

Data Management in Peer-to-Peer Data Integration Systems
Decentralized data management has been addressed during the years by means of several technical solutions, ranging from distributed DBMSs, to mediatorbased data integration systems. Recently, such an issue has been investigated in the context of Peer-to-Peer (P2P) architectures. In this chapter we focus on P2P data integration systems, which are characterized by various autonomous peers, each p...

متن کاملUtilizing XML Clustering for Efficient XML Data Management on P2P Networks
Peer-to-Peer (P2P) data integration combines the P2P infrastructure with traditional scheme-based data integration techniques. Some of the primary problems in this research area are the techniques to be used for querying, indexing and distributing documents among peers in a network especially when document files are in XML format. In order to handle this problem we describe an XML P2P system th...
متن کاملSome problem with current approaches to P2P Information Integration, and a possible research direction
Peer to Peer (P2P) networks are networks where each system (peer) can act both as data provider and consumer, without hierarchies or (crucial) dependencies on centralized components. P2P information integration takes place when, within some peer with respect to other peers, a dependency between provided and consumed information is established. Peers can either manage their own data schemas or a...
متن کاملAn Integration Model of Distributed Objects in a Virtual Repository Implementation basing on The ODRA OODBMS1
The paper deals with integration of distributed fragmented collections of data, being the basis for virtual repositories in the data grid or P2P architecture. The core of the described architecture is based on the StackBased Query Language (SBQL) and virtual updateable SBQL views. Our virtual repository transparently integrates distributed, heterogeneous and fragmented data producing conceptual...
