Evolution support in heterogeneous service-oriented landscapes

Abstract

We present an approach that provides automatic or semi-automatic support for evolution and change management in heterogeneous legacy landscapes where (1) legacy heterogeneous, possibly distributed platforms are integrated in a service oriented fashion, (2) the coordination of functionality is provided at the service level, through orchestration, (3) compliance and correctness are provided through policies and business rules, (4) evolution and correctness-by-design are supported by the eXtreme Model Driven Development paradigm (XMDD) offered by the jABC (Margaria and Steffen in Annu. Rev. Commun. 57, 2004)-the model-driven service oriented development platform we use here for integration, design, evolution, and governance. The artifacts are here semantically enriched, so that automatic synthesis plugins can field the vision of Enterprise Physics: knowledge driven business process development for the end user.We demonstrate this vision along a concrete case study that became over the past three years a benchmark for Semantic Web Service discovery and mediation. We enhance the Mediation Scenario of the Semantic Web Service Challenge along the 2 central evolution paradigms that occur in practice: (a) Platform migration: platform substitution of a T. Margaria ( ) Chair legacy system by an ERP system and (b) Backend extension: extension of the legacy Customer Relationship Management (CRM) and Order Management System (OMS) backends via an additional ERP layer.

ERP Integration - A Systematic Mapping Study

“…It is notable that most of the articles are case studies, use constructive approach or are based on literature only. In addition, a common qualitative approach such as ethnography is (Huang, 2002) CR (Wiers, 2002) CS CR (Ou-Yang and Hon, 2006) CR (Hu and Wang, 2008) CR (Wei et al, 2008) CR (Oman, 2011) CR (Siau and Messersmith, 2002) LS (Margaria et al, 2010) CS (Shafiei et al, 2012) CR (Tao et al, 2004) CR (Wang and Zhang, 2005) CR…”

“…Currently, an ERP system is just one of the many information systems used in organizations (Oman, 2011).The scope of ERP has advanced to Extended ERP or ERPII, in which the traditional ERP is integrated with other operational systems such as SCM (Supply Chain Management) and CRM (Customer Relationship Management) (Vathanophas, 2007). During the years, different technological solutions, including EAI (Enterprise Application Integration) and SOA (Service Oriented Architecture) have been introduced to solve the integration issues between these systems (Margaria et al, 2010;Wang and Zhang, 2005). A modern ERP is often accessed by mobile devices from different locations (Frank and Kumar, 2012;Jankowska and Kurbel, 2005).…”

Software diversity: state of the art and perspectives

“…Several authors address the evolution of particular types of models and focus on special challenges in this context. Examples are the evolution of reactive systems [172], software architectures [87] and workflow descriptions [46,139], e.g., based on domain-specific languages [120,84] and domain-specific modeling [39,128,159].…”

Simplicity Driven Application Development

“…It comprises various techniques for synthesis-supported development (Lamprecht, Naujokat, Margaria, & Steffen, 2010), verification (Bakera, Margaria, Renner, & Steffen, 2009;Steffen, Margaria, Claßen, & Braun, 1996), debugging (Niese et al, 2001;Raffelt, Merten, Steffen, & Margaria, 2009), execution, and, most importantly, for systematic system evolution (Jörges, Lamprecht, Margaria, Schaefer, & Steffen, 2012;Margaria, Steffen, & Kubczak, 2010).
