Tracing Data Lineage Using Schema Transformation Pathways

Using Schema Transformation Pathways for Data Lineage Tracing

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...

Tracing Data Lineage Using Automed Schema Transformation Pathways

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...

Investigating 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...

Lineage Tracing in a Data Warehousing System

A data warehousing system collects data from multiple distributed sources and stores the integrated information as materialized views in a local data warehouse. Users then perform data analysis and mining on the warehouse views. Figure 1 shows the basic architecture of a data warehousing system. In many cases, the warehouse view contents alone are not su cient for in-depth analysis. It is often...
