This paper discusses issues related to the data mapping phase of the integration of outsourced data, and introduces a set of mapping operators for both entities and attributes.

Abstract

Adopting and reusing outsourced data is becoming increasingly popular. We consider that the integration of outsourced data has two phases, namely relating schemas and data mapping. The former refers to relating entities and attributes between the source and the target schema. The latter refers to the mechanisms for the transformation of data. In this paper we discuss issues related to the data mapping phase. We introduce a set of mapping operators for both entities and attributes. A classification of possible mapping cases is presented. For each of the possible cases of mapping we also suggest a resolution method using the introduced mapping operators.

The VLDB JournalA survey of approaches to automatic schema matching

3,322 Citations2001Erhard Rahm, Philip A. Bernstein

A taxonomy is presented that distinguishes between schema-level and instance-level, element- level and structure- level, and language-based and constraint-based matchers and is intended to be useful when comparing different approaches to schema matching, when developing a new match algorithm, and when implementing a schema matching component.

This paper presents an approach based on formal ontologies presented in a logical language for integrating schemas to generate a global schema and shows how similarity relations are discovered by a reasoning system using a higher-level ontology.
