A survey on approaches to identify and develop webenabled services with respect to service-orientation paradigm and SOA: Towards a value-oriented approach

Service-Orientation (SO) is a new design paradigm to build software system solutions as compositions of reusable, distributed pieces of logic provided as services with respect to Service-Oriented Architecture (SOA). It is an evolution of the object-orientation and component engineering that emphasises loose coupling and interoperability in addition to enforcing the principles of separation of concerns and information hiding. However, we still lack approaches to identify and develop reusable services with respect to SO and consequently, SOA. First, this work presents a roadmap towards identification, development, and deployment of web-enabled services by surveying and comparing different approaches within a framework, consisting of: (1) software building blocks at different levels of abstraction and from different perspectives, namely business and technology, and (2) the principles of SO paradigm. Then, it presents issues that need further research, which would advocate for newer approaches based on the concept of service as value described in a standard contract and provided to any business or technology solutions upon request using messaging mechanisms.
