We discuss our recent approaches to enable the specication of a conceptual reconciled schema by directly manipulating source conceptual schemas. In particular, we use reverse engineering tools to reconstruct conceptual schemas when these are not available, and use iconic operators to specify how to map source schemas to the reconciled one. Moreover, we describe the mapping of the conceptual reconciled schema to a logical data model, including mechanisms to extract data from sources and loading them to reconciled database.

Abstract
We discuss our recent approaches to enable the specication of a conceptual reconciled schema by directly manipulating source conceptual schemas. In particular, we use reverse engineering tools to reconstruct conceptual schemas when these are not available, and use iconic operators to specify how to map source schemas to the reconciled one. Moreover, we describe the mapping of the conceptual reconciled schema to a logical data model, including mechanisms to extract data from sources and loading them to reconciled database.File in questo prodotto:
