摘要

当一个数据库要与其他数据库互操作时，必须首先将其模式转换为联邦系统的规范模型。这意味着一个知识获取过程来提升方案的语义层次。作者提出了一种将关系模式转换为语义丰富的面向对象模型的方法。它基于包含依赖关系，但也考虑了排除依赖关系和互补依赖关系

Semantic enrichment of database schemes: an object oriented approach

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.<>
