A specification language of XML-based e-business models

摘要

Electronic Commerce (EC) business models like c-brokers on the Internet use a large number of XML data such as product and customer data. To flexibly model such applications, we need a modeling language for EC businesses, specifically, business processes. First, as business process specification, we must allow users to retrieve only necessary portions of XML data centric in business models by specifying flexible search conditions. Second, we must allow users to combine XML data from different sources to produce new XML data for EC services. To this end, we have adopted a query language approach to modeling and have designed a query language for XML, suitable for supporting EC business models. In this paper, we discuss the needs for an XML query language for supporting EC business models and explain its functionality and validate its usability by specifying c-broker business models. We also discuss its applicability to other business models.
