This paper argues that the contextual properties of cloud-enabled software architecture should be identified and understood differently by cloud consumers. The existing architectures are not designed to exploit the contextual properties of cloud computing. The emergence of cloud computing virtually forces cloud consumers to re-evaluate their software architectures in light of the cloud computing context...
Information systems are complex and because society heavily depends on them, they have to be developed using the right enterprise architecture frameworks (EAFs). Although some major EAFs have been developed for more than a decade, information systems still fail to satisfy demands that organizations face and this reduces their competitive abilities. The failure may be due to the fact that either the...
Service-orientation has become the leading paradigm for modern IT system design and development as service-oriented system design has great potential for improving the efficiency and quality of the IT systems. This paper presents a model-driven approach for the generic integration of service-oriented architectures (SOA) and multi-agent systems (MAS). In fact, a model transformation from SoaML - a...
This paper focuses on adapting the Granular Theories to system modelling for design and development of a service-oriented system. It highlights how to integrate Granular Computing Structures, development philosophy, methodology and UML for modelling, organising and addressing systems through a case study of Emergency Assistance Service System (EAS). The proposed approach to building software development...
Modern distributed computer systems, with mobile and embedded devices as first class citizens, are formed from heterogeneous platforms. Owing to their distributed nature, dynamic reconfiguration and adaptation are reflecting different ownerships and administration domains of devices and applications. A portable, plug-in extensible runtime architecture is presented that explicitly honors ownership...
Over the past decade, granular computing has rapidly emerged as a new paradigm for distributed information systems. This paper describes an approach to develop service-oriented systems with granular computing theories and OMG standard UML (Unified Modelling Language)[1,4]. The paper goes on to outline how to integrate granular computing structures, methodology and UML for modelling, organising and...
In current research of agent, agent architecture is an important topic. Architecture of multi-agent system had been proposed to explain the relationship among the policy control layer, the self-control and behavior constraint layer, the organizational management layer and the middle connection layer. In policy control layer, we design two kinds of organizations, and a set of behavior rules, which...
SEAM is an enterprise architecture method based on RM-ODP part 2. In this paper, we present an example of a SEAM hierarchical model where the behavioral part is formalized in Alloy. We introduce four kinds of actions and their relationships to properties that specify object state. We show that the Alloy formalization enables us to check that the SEAM model conforms to the required aspects of the universe...
Like RM-ODP [1], enterprise architecture (or EA for short) has its own perspectives as a basic construct for its architecture definition to represent areas of concern. In this paper, difference between RM-ODP and one concrete example EA, and applicability of Use of UML for ODP system specifications [2] (or UML4ODP in short) standard to the example EA, are discussed. Several additional diagrams that...
The UNICORE grid system provides a seamless, secure and intuitive access to distributed grid resources. In recent years, UNICORE 5 is used as a well-tested grid middleware system in production grids (e.g. DEISA, D-Grid) and at many supercomputer centers world-wide. Beyond this production usage, UNICORE serves as a solid basis in many European and International research projects and business scenarios...
