摘要:The ability to handle complex data has made object oriented database gain a wide attention in the field of scientific research and engineering. Using object-oriented database for scientific data in it has several characteristics that should be considered for storing and retrieving it for future use. As this information needs to be exchanged and shared, XML in itself is emerging as a standard for information exchange over heterogeneous systems. The object oriented database structure designed using UML standard can be transformed into XML DTD. The XML DTD can further be used for obtaining DTD graph, which is further, used for extracting object oriented database schema by applying set of rules for class definition. This paper takes an example XML schema and transforms it into relational database schema. As object oriented database can be looked for more complex type of data handling compared to relational database, the XML schema is transformed to XML DTD and is used for representing object oriented database schema.
