Defining Peer-to-Peer Data Integration Using Both as View Rules
[chapter]

Lecture Notes in Computer Science

This paper extends an existing approach to data integration, called bothas-view, to be an efficient mechanism for defining peer-to-peer integration at the schema level, and demonstrates how the data integration ...
, and no schema is used to describe the data within those files. ...
Summary and Conclusions We have defined in this paper an extension to the BAV data integration approach to allow it to specify both sound queries and complete queries in transformations, and have demonstrated ...

The rewriting is supported by Global-As-View mappings that are supposed to pre-exist between specific schemas and standard ones. ...
These rules are defined in terms of assumed standard schemas for the peer databases they coordinate. ...
Many languages are available to define such mappings -datalog, description logics, views and so on. In this paper, we use views, because they are both expressive and simple. ...

These systems team up to build a network of nodes (peers) that coordinate at run time most of the typical DBMS tasks such as the querying, updating, and sharing of data. ...
Conventional multidatabase systems are founded on key concepts such as those of a global schema, central administrative authority, data integration, global access to multiple databases, permanent participation ...
While views and GLAV (global-andlocal-as-view) mappings have been used to integrate and exchange data within a common domain [5, 11, 15] , we consider what meta-data is required to share data across multiple ...

They each contain local data, a set of mapping tables and expressions, and a set of ECA rules that are used to exchange data among them. ...
The set of acquaintances and peers constitutes a dynamic peer-to-peer network in which acquaintances are continuously established and abolished. ...
Since the schemas of both peer databases are heterogeneous, no data exchange can take place before a form of homogenization is undertaken. In the more traditional context of data integration (see e.g. ...
