2005 EDOC: meeting the challenges of enterprise computing

An increasing demand for interoperable applications exists, sparking the real-time exchange of data across borders, applications, and IT platforms. To perform these tasks, enterprise computing now encompasses a new class of groundbreaking technologies such as Web services and service-oriented architecture (SOA); business process integration and management; and middleware support, like that for utility, grid, peer-to-peer, and autonomic computing. Enterprise computing also influences the processes for business modeling, consulting, and service delivery; it affects the design, development, and deployment of software architecture, as well as the monitoring and management of such architecture. As enterprises demand increasing levels of networked information and services to carry out business processes, IT professionals need conferences like EDOC to discuss emerging technologies and issues in enterprise computing. For these reasons, what started out as the Enterprise Distributed Object Computing (EDOC) conference has come to encompass much more than just distributed objects. So this event now used the name International EDOC Enterprise Computing Conference, to recognize this broader scope yet also retain the initial conference's name recognition.

Multi-model driven collaborative development platform for service-oriented e-Business systems

Enterprises need to be responsive to meet dynamic businesses and requirements. Service-oriented architecture and Web services can improve e-Business systems to be integrated and flexible. This paper proposes a multi-model driven collaborative development platform for service-oriented e-Business systems. The platform provides engineers/consultants with three views, i.e., business view, process view, and service view to support service-oriented software engineering, top-down business design and bottom-up service composite and development. The views are kept consistent through model-driven translation mechanisms. The platform employs three models, i.e., service meta-model, process model and business model to implement the translation. On the platform, business and technical consultants/engineers can use the views designated for their roles to collaborate for a service-oriented e-Business system based at the distributed sites of, e.g., IT vendors and their clients. The collaboration is featured with visual development and rapid demonstration. Comparingly, most of the mainstream development environments focus on object-oriented application development other than service-oriented business process modeling. The platform has been developed and deployed in an innovation centre to be evaluated by visiting customers.     

Frameworks for Enterprise Architecture

Enterprise architecture addresses the double challenge of increasing IT efficiency while continuing business innovation. Organizations can use enterprise architecture frameworks to manage system complexity and align business and IT resources. An enterprise architecture approach can help align business and IT resources and conform them to fundamental principles and common methodologies governing the entire information systems development process. In that sense, architectural frameworks are a convenient way to support such methodologies and separate roles that facilitate and implement these methodologies as needed. Still, many organizational and technical enterprise architecture challenges remain.

Virtuelle Entkopplung von fachlichen und IT-Strukturen für das IT/Business Alignment – Grundlagen,Architekturgestaltung und Umsetzung am Beispiel der Domänenbildung

IT/business alignment is one of the main topics of information systems research. If IT artifacts and business-related artifacts are coupled point-to-point, however, complex architectures become unmanageable over time. In computer science, concepts like the ANSI/SPARC three-level database architecture propose an architecture layer which decouples external views on data and the implementation view of data. In this paper, a similar approach for IT/business alignment is proposed. The proposed alignment architecture is populated by enterprise services as elementary artifacts. Enterprise services link software components and process activities. They are aggregated into applications and subsequently into domains for planning/design and communication purposes. Most design approaches for the construction of enterprise services, applications and domains are top-down, i. e. stepwise decompose complex artifacts. As an alternative which takes into account coupling semantics, we propose a bottom-up approach which is demonstrated for the identification of domains. Our approach is evaluated using a telecommunications equipment case study.
