"Web Services A Framework for B2B Integration"
Web Services: A Framework for B2B Integration Larry Kerschberg Co-Director, E-Center for E-Business George Mason University http://eceb.gmu.edu/ Panel Questions Is current technology sufficiently expressive for pure modeling or do we miss something? Difficult to determine because most approaches are proprietary and closely-held intellectual property. Used for competitive advantage. Panel Questions (continued) What are runtime challenges like throughput and performance in modeling approach? Modeling tools should allow us to express quality-of- service issues such as scalability, response time, availability, etc. (See ECEB Home Page). Why do many projects use programming rather then modeling? Time constraints, vendor-specific tool kits, lack of high-level modeling tools.! Panel Questions [continued] Is it possible to follow a 100% modeling approach for semantic B2B integration? Why bother with modeling at all? Do we have sufficient understanding of B2B requirements? Of course we do: Web Services to the rescue! Web Services allow companies to package their Intellectual Property and make it available as a service via the Internet.
