A decentralized XML database approach to electronic commerce
Hiroshi Ishikawa, Manasbu Ohta · 2002
Decentralized XML databases are often used in electronic commerce (EC) business models such as e-brokers on the Web. To flexibly model such applications, we need a modeling language for EC business processes. To this end, we have adopted a query language approach and have designed a query language, called XBML, for decentralized XML databases used in EC businesses. The authors explain and validate the functionality of XBML by specifying e-broker business models and describe the implementation of the XBML server, focusing on the distributed query processing.
