Validation of mappings between schemas
Mappings between schemas are key elements in several contexts such as data exchange, data integration, peer data management systems, etc. In all these contexts, the process of designing a mapping requires the participation of a mapping designer that needs a way to validate the mapping being defined, i.e., to check whether the mapping is in fact what the designer intended. However, to date very ...
متن کاملLearning Mappings between Data Schemas
To build a data-integration system, the application designer must specify a mediated schema and supply the descriptions of data sources. A source description contains a source schema that describes the content of the source, and a mapping between the corresponding elements of the source schema and the mediated schema. Manually constructing these mappings is both laborintensive and error-prone, ...
متن کاملDiscovering Simple Mappings Between Relational Database Schemas and Ontologies
Ontologies proliferate with the growth of the Semantic Web. However, most of data on the Web are still stored in relational databases. Therefore, it is important to establish interoperability between relational databases and ontologies for creating a Web of data. An effective way to achieve interoperability is finding mappings between relational database schemas and ontologies. In this paper, w...
متن کاملMaintaining Mappings between Conceptual Models and Relational Schemas
This paper describes a round-trip engineering approach for incrementally maintaining mappings between conceptual models and relational schemas. When either schema or conceptual model evolves to accommodate new information needs, the existing mapping must be maintained accordingly to continuously provide valid services. In this paper, the authors examine the mappings specifying “consistent” rela...
متن کاملComposing Mappings Between Schemas Using a Reference Ontology
Large-scale database integration requires a significant cost in developing a global schema and finding mappings between the global and local schemas. Developing the global schema requires matching and merging the concepts in the data sources and is a bottleneck in the process. In this paper we propose a strategy for computing the mapping between schemas by performing a composition of the mappin...
