Applying a Web Engineering Method to Design Web Services

摘要

Probably one of the most difficult tasks in the development of a Service Oriented Architecture (SOA) is how to obtain well designed Web Services. Some Web Engineering methods provide support to introduce Web services in the software development process but do not give support to the systematic design and implementation of them. In this work, we present an extension of a Web Engineering method (called OOWS) to provide a methodological guide for designing Web Services. This allows identifying and designing the operations and arguments of Web Services following a model-driven approach, taking the OOWS conceptual models as a source. To document our approach, we apply our ideas to the design of the Amazon Web Service and compare our proposal with the solution provided by Amazon.
