Service-Oriented Architectures have been proposed as a replacement for the more established Distributed Object Architectures as a way of developing loosely-coupled distributed systems. While superficially similar, we argue that the two approaches exhibit a number of subtle differences that, taken together, lead to significant differences in terms of their large-scale software engineering proper...

In this article we address the integration of functional models with non-functional models in the context of service-oriented enterprise architecture. Starting from the observation that current approaches to model-driven development have a strong focus on functionality, we argue the necessity of including non-functional aspects as early as possible in the service design process. We distinguish ...

Service Oriented Architecture (SOA) is an architectural style for developing and integrating enterprise applications to enable an enterprise to deliver self-describing and platform independent business functionality. Grid Computing (GC) is a framework that allows pooling of physical resources to enable virtualisation of distributed computing, enterprise data and enterprise functionality. The tw...

This paper addresses the problem of integrating various data sources and web services in an enterprise that uses a service-oriented architecture. We take advantage of ubiquitous enterprise concepts like Types of Things, Time and Position (What, When and Where) and build a context ontology for each that relates all the various representations across the enterprise. Then, we use Information Syste...

Despite the fact that nowadays, architectures, development processes, frameworks and technologies are maturing to be Service Oriented Architecture (SOA). Former frameworks for enterprise architecting couldn't be matched with those SOAs. Thus putting to use those frameworks to the business enterprises make IT/ICT consultants and enterprise architects encounter with some complex difficulties in t...

Service architectures are an increasingly adopted architectural approach for solving the Enterprise Application Integration (EAI) problem originated by business process automation requirements. In previous work, we developed a methodological framework for the designing of service architectures for EAI. The framework is structured in a layered architecture called LABAS, and is distinguished by u...

certain advantages of service-oriented architecture have led to the spread of this type of architecture around the world. however, some special features of this type of architecture have led to more compromise between the security in the information system and other information systems. the purpose of this paper is to identify and examine the impact of factors and dimensions of the information ...

In this paper we focus on a hardware realization of web services (WS) and their integration within the service-oriented architecture (SOA). Previous approaches to the implementation of network-enabled services in hardware covered only very specific types of applications and were platform-dependent. Our contribution is a generic framework where heterogeneous everyday objects are enhanced with ap...

Recently, the enterprise application integration has been a crucial requirement for the progress of EIS. However, the integration of those heterogeneous or distributed information systems often encounters problems related to complex management and maintenance, as well as low compatibility. Nevertheless, to totally abandon the former system or to re-develop a new great EIS may result in costly i...

N. Bieberstein S. Bose L. Walker A. Lynch In the fast-paced global economy, a corporation must be flexible and agile to meet the shifting needs of operating in an on demand environment. Aligning information technology (IT) systems using service-oriented architecture (SOA) to provide end-toend enterprise integration and virtualized IT services is a critical step. To be truly effective, however, ...
