摘要：

We refer to the concepts of object class, relationship type, and attribute of object class and relationship type in the ER model as ORA-semantics. Common database models such as the relational model and the XML data model do not capture these ORA-semantics which leads to many serious problems in relational and XML database design, data and schema integration, and keyword query processing in these databases. In this paper, we highlight the limitations and problems of current database research in these areas, and discuss how ORA-semantics can be utilized to resolve these problems.
