Semantic enrichment of database schemes: an object oriented approach
Malú Castellanos, Fèlix Saltor · 2002
When a database is to be interoperated with others, its scheme must first be converted to the canonical model of the federated system. This implies a knowledge acquisition process to upgrade the semantic level of the scheme. The authors present a methodology to convert relational schemas to a semantically rich object oriented model. It is based on inclusion dependencies, but also takes into account exclusion and complementariness dependencies.>
