An active web-based distributed database system for E-commerce
Hiroshi Ishikawa, Manabu Ohta · International Conference on Database Theory · 2001
ECbusiness models like e-brokers on the Web use WWW-based distributed XML databases. To flexibly model such applications, we need a modeling language for EC businesses, specifically, its dynamic aspects or business processes. To this end, we have adopted a query language approach to modeling, extended by integrating active database functionality with it, and have designed an active query language for WWW-based XML databases, called XBML. In this paper, we explain and validate the functionality of XBML by specifying e-broker and auction business models and describe the implementation of the XBML server, focusing on the distributed query processing in the WWW context.
