RDB-based Approach to Domain Ontology for Contingency Plan

The paper proposed an automatic modeling method on domain ontology for contingency plan based on RDB. Logic model and conceptual model were gotten by Rational Rose,a tool of database reverse engineering,and physical model was achieved by querying system tables of RDB,and then defined transform rules through analyzing RDM's normal and unnormalized relations. The experiment shows that the method can automatically model domain ontology from RDB for contingency plan effectively,and it also improves the construction rate of domain ontology and promotes the contingency plan digital process.
