Database Integration: the Key to Data Interoperability

Stefano Spaccapietra, Christine Parent

Most of new databases are no more built from scratch, but re-use existing data from several autonomous data stores. To facilitate application development, the data to be re-used should preferably be redefined as a virtual database, providing for the logica ...

Supporting Multiple Representations inSpatio-Temporal databases

Stefano Spaccapietra

Successful information management implies the ability to design accurate representations of the real world of interest to targeted applications. Current systems do not provide representation schemes supporting the diversity of user needs. In the context of ...

Spatio-Temporal Conceptual Models: Data Structures + Space + Time

Stefano Spaccapietra, Christine Parent

Nowadays, many applications need data modeling facilities for the description of complex objects with spatial and/or temporal facilities. Responses to such requirements may be found in Geographic Information Systems (GIS), in some DBMS, or in the research ...

MADS ou l'information spatio-temporellee à portée de ses utilisateurs

Stefano Spaccapietra, Christine Parent, Christelle Vangenot, Pier Donini

Malgré les bienfaits reconnus de l'approche conceptuelle pour la modélisation dÕapplications, les modèles conceptuels spatio-temporels existants ne satisfont pas les besoins des concepteurs. Dans cet article nous présentons brièvement le modèle MADS selon ...

Modeling Spatial Data in the MADS Conceptual Model

Stefano Spaccapietra, Christine Parent, Christelle Vangenot, Pier Donini

Despite the well-established benefits of conceptual modeling for application design, current spatio-temporal conceptual models do not cope satisfactorily with designers' requirements. In this paper we first identify the goals of a spatio-temporal conceptua ...

Database Integration: an Overview of Issues and Approaches

Stefano Spaccapietra, Christine Parent

In many large companies the widespread usage of computers has led a number of different application-specific databases to be installed. As company structures evolve, boundaries between departments move, creating new business units. Their new applications w ...

Modeling Time from a Conceptual Perspective

Stefano Spaccapietra, Christine Parent

Although many temporal models have been proposed in the literature, there is still need for a conceptual model capturing the essential semantics of time-varying information that is free of implementation concerns. This paper first discusses important crite ...

Conceptual Modeling for Federated Geographical Information Systems over the Web

Stefano Spaccapietra, Christine Parent

A conceptual model provides the best support for federating heterogeneous datastores into a unified framework and elaborating a global consistent description of all available data. It therefore plays a central role for exchange of information within the co ...
