We introduced a new approach, termed schema coordination, as an alternative to the well-known schema integration approach for processing cooperative queries in federated database systems. The schema coordination approach is based on the attribute correspondence matrix that links similar attributes in all component databases. In this paper, we compare the schema coordination approach with the sc...

Heterogeneous Business Process Modeling (BPM) schemas have been a problem for business process management throughout the last couple of years. Although there are several standardization efforts in this area, none of the proposals is commonly accepted as a de facto standard in the industry. Methodological guidance is needed in order to consolidate concurrent schema proposals especially in the BP...

Schema integration is one of the most difficult issues in the heterogeneous and distributed geographic database systems (GDSs). As the use of spatial information in various application areas becomes increasingly popular, the integration of geographic information has become a crucial task for decision makers. Most existing schema integration techniques described in the database literature, howev...

Global schema generation is the problem of generating a unified schema based on existing heterogeneous local schemas and a set of correspondences which are generated by a schema matching algorithm. The current schema integration approaches cannot satisfy users' requirements due to several reasons. The existing approaches cannot handle hierarchical schema structure, cannot solve conflicts proble...

In this paper we address the problem of how to apply the schema integration techniques in the legacy system migration since some issues in the legacy concept: legacy system migration and reengineering are closely related to the schema integration methods. The importance of introducing integration issues to legacy system migration lies in the following aspects: 1) To adapt the legacy systems to ...

This dissertation addresses the problem of semi-automatically creating schema mappings. The need for developing schema mappings is a pervasive problem in many integration scenarios. Although the problem is well-known and a large body of work exists in the area, the development of schema mappings is today largely performed manually in industrial integration scenarios. In this thesis an approach ...

From: ‘Advanced Information Systems Engineering’, 14th International Conference, CAiSE 2002, A. Banks Pidduck et al (Eds), Springer Verlag LNCS 2348, Pages 484-499, 2002 This paper presents a new approach to schema evolution, which combines the activities of schema integration and schema evolution into one framework. In previous work we have developed a general framework to support schema trans...

This dissertation lies in the research area of schema integration: the problem of combining the data of different data sources by creating a unified representation of these data. Two core issues in schema integration are schema matching, i.e. the identification of correspondences, or mappings, between input schema objects, and schema merging, i.e. the creation of a unified schema based on the i...

There is considerable interest in developing distributed information systems on top of legacy systems. Over the last two decades, many issues and solutions have been brought forward pertaining to issues of integration, e.g., schema integration, schema mapping. We have developed a schema mapping framework that features domain-specific metamodels, metamodel-driven schema translation, and semiauto...
