The development of service computing technology has triggered the need for organizations to build a service computing system. This system is able to deliver IT services that can meet the challenges and needs of business services. An understanding of the service computing systems engineering life cycle is necessary to model and build the systems. This paper conducts the study of the service computing...
Integration of hospital information systems (HIS) is an important area and one the basic requirements of hospitals since it increases quality of care and at the same time reduces costs of creating, upgrading, updating and keeping up with technology and healthcare industry standards and information technology. Cloud computing with features like multitenancy, massive scalability, elasticity, pay as...
In the service oriented, customer centric and cloud computing based market environment where network and IT is becoming converged and the Telecom enterprise is transformed to be of a more virtual or even purely virtual organized enterprise, telecommunication operators are, and will be, facing huge challenges to deliver new services and products to their customers in different market segments — from...
Agricultural knowledge is so distributed, heterogeneous and polymorphic that current web architecture may unable to find the desired search results. So ontology of semantic web architecture is used for better search results. Semantic web makes the data of the web machine understandable and ontology is the core step of semantic web technology. Ontology captures the domain knowledge in a generic way...
Service Oriented Architectures (SOA) with all technologies especially web services provide a successful model for structuring complex distributed software systems, as they reduce the cost of ownership and easiness of the creation of new applications by composing existing services. However, the developments of service-oriented applications require many external manual tasks and prevailing infrastructure...
The rapid changes of information technology led to the proliferation of Web-based Information Systems (WIS). There has been already some research on the general model for analysis and design of WIS. This paper attempts to define a comprehensive framework for integrating the various viewpoints of model for WIS. Several components that compose of a WIS as analyzing and designing element are investigated...
Service Oriented Architecture, which builds on distributed computing platforms, is increasingly being adopted by organizations in both public and private sectors. Migration from traditional monolithic systems to services, in particular web services, characterizes much of systems evolution today. This paper analyzes some of the performance and modularization problems involved in current service-oriented...
This paper addresses the challenges of large commercial and government that struggle with requirements understanding, increasing delivery quality and estimating costs. The paper discusses Smarter Architecture & Engineering (SmarterAE) as an approach that applies scrutiny, metrics and analysis to architecture, requirements management and engineering as is historically given to development, testing...
To resolve the problem of agile that can satisfy growing consumer expectations and stay ahead of the competition, this paper introduces a solution of architecture combining service-oriented architecture (SOA) and business process management (BPM). First, we explain the definition and characteristics of SOA; second, we introduce the concept and mechanism of BPM and BPMS; finally, we give an simple...
Railway Foundational Database is characterized as highly systematic, huge data volume and different data affiliation, Railway Foundational Database platform is physically distributed ,logically centralized ,easy to expand and so on. After elaborating the characteristics of Railway Foundational Data and Foundational Database Platform Architecture, we design a Foundational Database Platform Architecture...
Reliability of web applications depends on reliability of the application itself as well as the underlying application server, external and internal services. Many research works have been conducted on reliability modeling of service-based software, which concentrate on internal services located in the organization. The purpose of this in-progress study is to analyze the reliability of service-based...
The adoption of Enterprise Architecture (EA) concepts within organizations is causing an interest in the methodologies and supporting technologies available. Service Oriented Architecture (SOA) supports EA in many facets. However, there is much dissolution with regard to the relationship between EA and SOA within organizations. There are also potential problems that may arise if this relationship...
Nowadays, several network applications require that consumer nodes acquire distributed services from unknown service providers on the Internet. The main goal of consumer nodes is the selection of the best services among the huge multitude provided by the network. As basic criteria for this choice, service cost and Quality-of-Service (QoS) can be considered, provided that the underlying Service-Oriented...
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...
The concept of Service Oriented Architecture (SOA) has had a significant impact not only on software engineering but on the analysis of an organization's business layer as well. In this paper we demonstrate that using the SOA concept into the Enterprise Architecture (EA) framework makes the best of the synergy existing between these two approaches. We will examine the characteristics of this relationship...
In the present paper we discuss the concepts on which is based the GEMBus framework, a multi-domain, federated Enterprise Service Bus. Then, we show certain production scenarios as general use-cases, and a brief analysis of the selected platforms for the basis of the framework. Furthermore, we discuss the role that Autonomic Computing (AC) services play on the framework, showing a representative scenario...
ITIL V3 could be introduced as a governance framework for IT service management (ITSM) and attempts to align IT investments with business objectives. Enterprise Architecture (EA) is also referred as a general framework for designing business and IT/IS architectures of organizations and it also attempts to align these architectures with business strategies. Our research tends to provide a service based...
Based on the comparison of advantage and disadvantage between Google and digital library, a method for service chain of digital library based on service-oriented architecture (SOA) is presented. Then an integrated framework for service chain of digital library is put forward, and the information exchange approach and software system architecture layers based on SOA are discussed. Finally, based on...
Ultra large scale (ULS) systems are future software intensive systems that have billions of lines of code, composed of heterogeneous, changing, inconsistent and independent elements that are dispersed through worldwide global networks. Huge scale of this heterology in addition to distinctive characteristics like decentralization of operation, management, deployment and evolution, continuous evolving,...
Within the current economic context, enterprises are facing new interoperability issues due to increasing need of e Business Collaboration within the emerging digital ecosystems in which they belong. They also need to be able to keep in pace with their heterogeneous internal legacy systems, and can't change their infrastructure or applications for fast and short collaboration implying information...
