ABSTRACT
A key aspect of any data integration endeavor is determining the
relationships between the source schemata and the target schema. This schema
integration task must be tackled regardless of the integration architecture or
mapping formalism. In this paper, we provide a task model for schema
integration. We use this breakdown to motivate a workbench for schema
integration in which multiple tools share a common knowledge repository.
In particular, the workbench facilitates the interoperation of research prototypes
for schema matching (which automatically identify likely semantic
correspondences) with commercial schema mapping tools (which help produce
instance-level transformations). Currently, each of these tools provides its own
ad hoc representation of schemata and mappings; combining these tools
requires aligning these representations. The workbench provides a common
representation so that these tools can more rapidly be combined.
