The SOA Paradigm and e-Service Architecture Reconsidered from the e-Business Perspective

Abstract

A business service has well founded structure where its operations (corresponding to request-quote, order-contract, invoice-payment) are related to each other. These relations cannot be expressed in WSDL. The request-quote operation corresponds to SLA negotiations and can be performed in a universal description language such as OWL that can also express all the relations between service operations mentioned above. Generally, from the e-business perspective the following notions are important: (1) Service architecture. (2) Communication protocols in e-business processes. These notions are crucial for providing standards necessary for creating open, heterogeneous and scalable systems for realizing complex e-business processes. These notions are discussed in the paper.
