Incremental view maintenance and data lineage tracing in heterogeneous database environments
With the increasing amount and diversity of information available on the Internet, there has been a huge growth in information systems that need to integrate data from distributed, heterogeneous data sources. Automed (Automatic Generation of Mediator Tools for Heterogeneous database Integration) is a database transformation and integration system, which is designed to support virtual and materi...
متن کاملInvestigating a heterogeneous data integration approach for data warehousing
Data warehouses integrate data from remote, heterogeneous, autonomous data sources into a materialised central database. The heterogeneity of these data sources has two aspects, data expressed in different data models, called model heterogeneity, and data expressed within different schemas of the same data model, called schema heterogeneity. AutoMed is an approach to heterogeneous data transfor...

With the increasing amount and diversity of information available on the Internet, there has been a huge growth in information systems that need to integrate data from distributed, heterogeneous data sources. Tracing the lineage of the integrated data is one of the problems being addressed in data warehousing research. This paper presents a data lineage tracing approach based on schema transfor...
متن کاملUsing AutoMed for XML data transformation and integration
This paper describes how the AutoMed data integration system is being extended to support the integration of heterogeneous XML documents. So far, the contributions of this research have been the development of two algorithms. One restructures the schema describing an XML document into another schema, and the other materialises an integrated schema resulting from the transformation of several so...
