Horses for Courses: Services, Objects, and Loose Coupling - Integration without compromise

Wed, 31 Dec 2003 09:37:09 EST

Object-oriented technologies are used today in the design and development processes for many computer systems; it is a proven paradigm and has made possible the development of large and complex software systems. Enabling platforms and tools for building and consuming Web services will not be an exception.

Introducing WS-CAF - More than just transactions

Mon, 01 Dec 2003 00:00:00 EST

Demystifying Service-Oriented Architecture

Mon, 27 Oct 2003 00:00:00 EST

With the emergence of Web services into the mainstream the developer has to learn how to architect and build service-oriented systems. While service orientation isn't a new concept, the rapid convergence of the industry on Web services technology has brought the concept of service-oriented architectures (SOA) to the forefront of many developers' minds.

In part 1 of this article (WSJ, Vol. 2, issue 10), you saw how simply BTP toolkits can support the creation of applications that drive transactional Web services with consummate ease. This article covers the other side of the story: how the same technology impacts Web services developers.

Web Services Infrastructure

Mon, 23 Sep 2002 00:00:00 EDT

It's a fact: Web services have started to mature. Those emergent standards that once held so much promise are now actually starting to deliver useful implementations. With the basic Web services plumbing mastered, we're starting to see more advanced infrastructure, which enables these second-generation Web services to focus on complex interactions over the Internet.
