An efficient structure for an object-oriented database

New technologies have been continuously introduced in the e-business environment since the emergence of e-commerce. For example, ebXML (electronic business extensible markup language) has been adopted instead of EDI (electronic data interchange) for exchanging electronic documents, or RDB (relational database) is being replaced by OODB (object oriented database) for storing data. In view of the fact ebXML is based on the object-oriented concept, OODB is more efficient than RDB or XML-based e-business system. In this paper, we introduce the electronic document using XML and the object-oriented database instance instead of tables or fields of RDBMS. One of the most important things in designing database is to define the classification rules for choosing elements or attributes among meaningful values. We also propose a system architecture that reflects the ebXML concept and an implementation method using a distributed and component-based architecture.
