    Motivated by the objective to provide an improved participation of business domain experts in the design of service-oriented integration solutions, we extend our previous work on using the COSMO methodology for service mediation by introducing a goal-oriented approach to requirements engineering. With this approach, business requirements including the motivations behind the mediation solution are better understood, specified, and aligned with their technical implementations. We use the Payment Problem Scenario of the SWS Challenge to illustrate the extension

    Programmes in transition - between closure and start. Review of programme developments: Winter-Summer 2007

    The past six months have seen a shift in emphasis from the 2000-2006 to the 2007-2013 programmes. Programme managers and other implementing organisations have not only been negotiating draft programmes for 2007-2013 with European Commission staff, but have also been undertaking a range of tasks to prepare for implementing these programmes. A number of initiatives have also occurred at EU level, which direct policymakers’ attention forward to the EU budget review of 2008-2009 and beyond. In addition, ongoing efforts have been needed to ensure that the remaining funds under the 2000-2006 programmes are effectively absorbed, and that all technical preparations for programme closure are underway

    Towards a flexible service integration through separation of business rules

    Get PDF
    Driven by dynamic market demands, enterprises are continuously exploring collaborations with others to add value to their services and seize new market opportunities. Achieving enterprise collaboration is facilitated by Enterprise Application Integration and Business-to-Business approaches that employ architectural paradigms like Service Oriented Architecture and incorporate technological advancements in networking and computing. However, flexibility remains a major challenge related to enterprise collaboration. How can changes in demands and opportunities be reflected in collaboration solutions with minimum time and effort and with maximum reuse of existing applications? This paper proposes an approach towards a more flexible integration of enterprise applications in the context of service mediation. We achieve this by combining goal-based, model-driven and serviceoriented approaches. In particular, we pay special attention to the separation of business rules from the business process of the integration solution. Specifying the requirements as goal models, we separate those parts which are more likely to evolve over time in terms of business rules. These business rules are then made executable by exposing them as Web services and incorporating them into the design of the business process.\ud Thus, should the business rules change, the business process remains unaffected. Finally, this paper also provides an evaluation of the flexibility of our solution in relation to the current work in business process flexibility research
