Integrated Data Mapping for a Software Meta-tool

Jun Huh, John Grundy, John Hosking, Karen Liu, Robert Amor
2009 2009 Australian Software Engineering Conference  
Complex data schema and mapping relationships are represented in multiple, high-level notational forms and users are provided semi-automated mapping assistance for large models.  ...  Developers can quickly develop stand alone data mappers and model translation and code importexport components for their tools.  ...  However, mapping large complex data models textually means translator authors still lack support for visualizing relationships and understanding the larger structure of the mappings and schema [13] .  ...

Using agents for generation and maintenance of mediators

Bernadette Farias Lóscio, Ana Carolina Salgado, Vânia Maria Ponte Vidal
2002 Journal of the Brazilian Computer Society  
In this paper we present a system for data integration on the web, where an XML-based mediator plays a key role providing a homogeneous view of different data sources.  ...  One novelty of our approach is that we also propose solutions for the problems of generation and maintenance of mediators.  ...  MOMIS (Mediator envirOnment for Multiple Information Sources) is a framework for extraction and integration of structured and semi-structured data.  ...

BDOviedo3: Data XML Storage and Management [chapter]

Ana Belén Martínez, Darío Álvarez, Francisco Ortín, Juan Manuel Cueva, Ma Ángeles Díaz
2003 Lecture Notes in Computer Science  
OOBDMS provide a good solution for the management of XML documents.  ...  This article shows the different approach (specific and generic) of coupling an object model with XML and emphasizes the possibilities offered by BDOviedo3 system.  ...  It is based on extending the ODMG standard to support structured and semi-structured data. This implies the existence of a model to represent semi-structured data (OEM in the case of Ozone [8] ).  ...

Evaluations of Conceptual Models for Semi-structured Database System

Rita Ganguly, Anirban Sarkar
2012 International Journal of Computer Applications  
As a consequence, structured and semi structured data cannot be treated in an integrated, holistic way during requirements specification.  ...  A number of features which can be considered interesting for a semi structured data model are listed.  ...  However, the XML schemas provide the logical representation of the semi-structured data and it is hard to realize the semantic characters of such data.  ...
