Schema Level and Data Level Mapping Composition
Schema mappings and data mappings constitute essential building blocks of data integration, data exchange and peer-to-peer data sharing systems. At present, either schema-level mappings or datalevel mappings are used for data sharing purposes. In this paper we consider the semantics of bi-level mapping that combines the schema-level and data-level mappings. Tabular representation of the mapping...
متن کاملSchema Mapping Evolution Through Composition and Inversion
Mappings between different representations of data are the essential building blocks for many information integration tasks. A schema mapping is a high-level specification of the relationship between two schemas, and represents a useful abstraction that specifies how the data from a source format can be transformed into a target format. The development of schema mappings is laborious and time-c...

متن کاملFrom XML Schema to Object-Relational Database - An XML Schema-Driven Mapping Algorithm
Since XML becomes a crucial format for representing information, it is necessary to establish techniques for managing XML documents. A possible solution can be found in storing XML data in (object-)relational databases. For this purpose most of the existing techniques often exploit an XML schema of the stored XML data, usually expressed in DTD. But the more complex today’s applications are, the...
متن کاملDesigning a Knowledge-based Schema Matching System for Schema Mapping
Schema mapping that provides a unified view to the users is necessary to manage schema heterogeneity among different data sources. Schema matching is a required task for schema mapping that finds semantic correspondences between entity pairs of schemas. Semi-automatic schema matching systems were developed to overcome manual works for schema mapping. However, such approaches require a high manu...
