摘要

Looking at the recent history of information systems, two complementary trends seem to emerge. On the one side, systems become more modular. The shift is from tight integration to loosely coupled components. On the other side, the distance between business models and information technology (IT) is shortening. Aggressive business models impose new requirements on IT. At the same time, operational capabilities made available by IT drive the definition of new business models. Web services are the most noticeable outcome of the first trend. E-services play a similar role for the second trend. In this paper, we concentrate on e-services and their relationships with the type of business processes used by e-businesses. We refer to this type of processes as e-processes. We first introduce e-services, and outline the interconnections with web services. Focusing on the composition aspects of e-processes and e-services, we then discuss potential and requirements of process-level cooperation for composite e-service solutions. We refer to these composite solutions as e-networks. The discussion is based on our work on the DySCo (Dynamic e-Service Composer) framework for e-network management. A brief description of the framework and the associated platform is included, together with an analysis of some of the issues related to service level agreements (SLAs) in e-networks.
