7/1/1987 · TRANSFORMING EXTENDED ER DIAGRAMS 185 Implementation and verification of the transformation algorithm is currently under investigation. The following steps summarize the basic concepts in the formation of relations from the EER diagram: (1) Define a data object to represent each set of n entities with a rela- tionship among them (for n > 0).
Steps in designing an ER schema Translation of an ER schema to tables Dept. of Computer Science UC Davis 2. Entity-Relationship Model. ECS-165A WQ’11 16 What does Conceptual Design include? Ideas ! High-level design! Relational database schema! Relational DBMS Entity-Relationship model is used in the conceptual design of, two steps : the first step is transforming an XML document into entity-relation model (XTR) then transforming entity-relation model into OWL ontologies (RTO) as second step . In [9] Nora and colleagues proposed an approach to generate automatically OWL ontologies from multiple XML data sources based on different XML schema design styles.
