In: Proceedings of International conference on Managing Services in the Knowledge Economy ; 13-15 July 2011, Famalicão, Portugal, pp. 489-500978-989-640-103-0http://hdl.handle.net/10400.15/596An explanation of the current methods used in Web service composition within a Service Oriented Architecture (SOA) is presented. We found that composite business applications can be formed by Web service orchestration using the BPEL programming language, which permits the execution of business process logic. Mashups, simple composite applications that are usually used for ad hoc situations, do not need to be orchestrated, and could be composed using lightweight Web services. Such Web services are aggregated using current tools that are simple to use. Our study was based on a theoretical literature review, and is useful in understanding ways that different business users can build applications within the SOA, according to their needs and their technical competences.engMashupService Oriented Architectureconference object
