Interactive Generation of Integrated Schemas (2009)
Laura Chiticariu, Phokion G. Kolaitis, Lucian Popa
Schema integration is the problem of creating a unified target schema based on a set of existing source schemas that relate to each other via specified correspondences. The unified schema gives a...
ABSTRACT Debugging Schema Mappings with Routes ∗ (2008)
A schema mapping is a high-level declarative specification of the relationship between two schemas; it specifies how data structured under one schema, called the source schema, is to be converted...

Muse: A System for Understanding and Designing Mappings (2008)
Bogdan Alexe, Laura Chiticariu, Renée J. Miller, Wang-chiew Tan
Schema mappings are logical assertions that specify the relationships between a source and a target schema in a declarative way. The specification of such mappings is a fundamental problem in...

DBNotes: A Post-It System for Relational Databases based on Provenance (2005)
Laura Chiticariu, Wang-chiew Tan, Gaurav Vijayvargiya
We demonstrate DBNotes, a Post-It note system for relational data. In DBNotes, it is possible to attach zero or more notes to every value in a relation. When a relation is queried, DBNotes propagates...
DBNotes: A Post-It System for Relational Databases based on Provenance (2005)
We demonstrate DBNotes, a Post-It note system for relational databases where every piece of data may be associated with zero or more notes (or annotations). These annotations are transparently...
