Service-oriented architecture (SOA) is for flexibility and reuse, and enables organizations to easily integrate systems, data, applications and processes through the linking of services. SOA also addresses the critical security and privacy issues. This paper focuses on the investigation and studies on SOA based software engineering methods in the service engineering environment. Among the various SOA related software design and development methods available, service-oriented modeling and architecture (SOMA) service architectural environment is chosen as the target platform in the study. A web based service oriented ubiquitous Healthcare (u-Healthcare) software system was designed and implemented using the set of the software engineering methods developed in the study to gain empirical knowledge and experience on applying the approach to construct SOA service software.
