When I started to think about writing this month's column I looked on the Internet for a good way to define service-oriented architecture (SOA). Some of the definitions were interesting, like 'A Service Oriented Architecture is basically a Collection of Services' (www.service-architect...
As enterprises build a critical mass of Web services, they need some way of keeping track of those services. UDDI is an ideal store for such information. Using UDDI's built-in abstractions of business services, binding templates, and tModels referring to interface specifications, UDDI ...
This article describes recent work in a leading investment bank using Microsoft's BizTalk Server 2004 (BizTalk) as an integral component of a service-oriented architecture. I'll describe how BizTalk is used to implement lightweight workflow that builds new services from existing servic...

Integration remains the number one IT priority; fully 60-70% of IT budgets are dedicated to it. Web services makes integrations simpler and cheaper. It makes B2B integrations practical. What businesses demand from a service-oriented architecture (SOA) is dynamic integration capability....
While widely adopted or standardized security protocols are great for interoperability, a set of SOAP message header elements as well as a few new elements that belong in the message body are outside the scope of the existing mechanism for publishing service descriptions, which is WSDL...
