When a process is upgraded, the in-flight instances will either be aborted if the processes were not versioned or the deployment will fail depending upon the mode on wh... (more)

Web Services Interoperability

Web services has been promising to solve several business problems, including those of integration and interoperability. While Web services standards like SOAP, WSDL, and UDDI help to facilitate it, they don't really ensure it. In the past, application-to-application integration and business-to-business integration were not easy due to the various platforms involved or different software used.

Building Business Processes Part 1

A business process in the real world typically is never done end-to-end by a single employee.

Applications and Business Processes - What's the Difference?Typically, programmers think in terms of applications (e.g.... (more)

SOA Testing Framework

Service-oriented architecture (SOA) has become today's technology buzz and it's rapidly becoming a mainstream approach to enterprise systems design. Beyond the buzz of SOA, organizations face several challenges as they attempt to truly effectuate the paradigm shift towards SOA. One critical challenge is: How can we assure the quality of the business services that we build? Can the services we build withstand the test of rapid organizational change? One way to address this challenge is through the use of effective testing methodologies and tools for the services deployed under an ... (more)
