The semantical integrity of business data is of great importance for the implementation of
business applications. Model-Driven Software Development (MDSD) allows for specifying …

Today many organizations are facing the need to integrate multiple, previously independent
but semantically related information sources. Although often the quality and integrity of the …

In schema integration, schematic discrepancies occur when data in one database
correspond to metadata in another. We explicitly declare the context that is the meta …

A critical reality in data integration is that knowledge from different sources may often be
conflicting with each other. Conflict resolutioncan be costly and, if done without proper …

In this paper we discuss the use and treatment of integrity constraints in the federated
database design process. We consider different situations occurring frequently in the …

We discuss the applicability of schema integration techniques developed for tightly-coupled
database interoperation to interoperation of databases stemming from different modelling …

In this work, we address the problem of constraint conflicts while integrating the conceptual
schemas of multiple autonomous databases modeled using the Entity Relationship (ER) …

Integrating heterogeneous database schemata is a major task in federated database design
where preexisting and heterogeneous database systems need to be integrated virtually by …
