Data Freshness Evaluation in Different Application Scenarios
Résumé
Data freshness has been identified as one of the most important data
quality attributes in information systems. This importance increases especially in
the context of systems that integrate a large set of autonomous data sources. In this
paper we describe a quality evaluation framework which allows evaluation of data
freshness in different architectural contexts. We also show how this quality factor
may impact the reconfiguration of a data integration system to fulfill user
expectations.
