Résumé:
This work presents a Knowledge based system to integrate database schemas.
The system incorporates the main aspects of the most significant methodology to
integrate the schemas. It's an evolutionary and flexible system once it's possible to
include new rules to its knowledge-base extracted from new proposed methodologies or
from the users experience with database integration. The system knowledge base uses
production rules to represents its knowledge over the schema integration. It also uses
frames and logical representation to model structural facts, constituting a hybrid system
that uses the advantages of these three forms of knowledge representation. It uses a
graphical interface to manipulate the schemas, offering explanation of the decisions
taken and questions asked by the system. That offers training to the least experienced
users.
