On View Transformation Support for a Native XML DBMS

XML is becoming the standard data exchange format. View transformation of XML data is important and frequent operation in XML data integration and publishing. In schema-based view transformation, users define view schema over sources to obtain view results. This declarative approach alleviates user from writing complex scripts to perform view transformation. Current available schema formats are unable to express views with complex semantic constraints. In this paper, we introduce a semantically expressive XML data model: Object-Relationship-Attribute model for Semi-Structured data (ORA-SS), which allows users to define view schemas with rich semantic meanings. Combine with ORA-SS, we use a native XML DBMS: OrientStore to perform accurate and efficient view transformation.
