Software module clustering is generally a difficult and challenging problem in software engineering. In the same way, service identification plays a critical role in service engineering. Existing Service identification approaches are often prescriptive and based on the architect's experience thus could result in non-optimal designs which results in complicated dependencies between services. In this...
The growing demand for electricity has forced towards the implementation of smart grid where the various participants share and communicate power system data to trade electricity and control electrical power systems. Though service orientation acts as a promising technology to solve integration problems among these domains, data exchange and information interpretation are continuing to be challenges...
This paper describes a method for the implementation and optimization of business processes in a service oriented architecture (SOA). A process specification is created by business people, and expressed in Business Process Modeling Notation (BPMN). The specification is then translated into Business Process Execution Language (BPEL), and used by technical people as a reference process, which is subject...
Goal modeling is a prominent design paradigm in various domains of information systems engineering. In the field of service oriented computing (SOC) and in the field of semantic web services, emergent research works are basing their engineering approach on the goal concept. Because of the complexity of processes underlying SOC, the usage of the goal concept can vary to a large extent. In this paper,...
BPEL is a popular standard language in SOA enterprise for specifying business process. A developer has to use specific programming technologies to construct process structure and specify Web services inputs and outputs in the process. It is time-consuming to specify every business process from low-level Web services. This paper proposes a semantic extended BPEL model for SOA process generation, and...
Enterprise Architecture (EA) Modelling aims to analyze an organization in terms of its components, IT systems and business processes. Current modelling approaches are based on Service Oriented Architecture (SOA) whereby components publish interfaces of operations that are used via message passing. It has been argued that SOA leads to tight coupling between components and does not handle complex component...
RESTful web services, which are declarative, light-weight and easy-to-access, have attracted increasing interest from industry and are already widely used for exposing their services on the Internet. However, the formalism of RESTful web services, especially in terms of automatic composition, is still under explored compared to the extensive research in RPC-style web services. This paper introduces...
With the development of SOA, the hot researches focus on disaster recovery of business systems change to the recovery of SOA business process. SOA- based business has such advantages as loosely coupled, standards-based, and protocol-independent distributed computing, which make SOA-based business systems much stronger than traditional business system. In this paper a kind of SOA business architecture...
Intentional services have been proposed to bridge the gap between low level, technical software-service descriptions and high level, strategic expressions of business needs for services. This proposal leverages on the SOA to an intentional level, and introduces the iSOA architecture. Derived from business specifications by service providers, intentional services are referenced in an extended registry...
Service modeling became important in the recent years, due to successful uptake of the SOA based environments and business models, pushed forward by overall growth of the service sector as a leading part of the worldwide economy. Service modeling gained importance based on the requirement to better understand, define and control the services as basic building blocks of the SOA based environments....
Dynamic composition of services provides the ability to build complex distributed applications at run time by combining existing services, thus coping with a large variety of complex requirements that cannot be met by individual services alone. However, with the increasing amount of available services that differ in granularity (amount of functionality provided) and qualities, selecting the best combination...
Low coupling is a service-oriented design and development principle that should be taken into account during all stages. Having loosely coupled services not only increases service reusability, but also prevents the propagation of changes to other services and thus simplifies maintenance of service-oriented systems as well. In this paper, we focus on measuring conceptual coupling as an indicator of...
Modularity is one of the prominent principles in designing services which must be adhered during service design. Services can be simply defined as modular units which concentrate on a single business functionality. Focusing on a single business functionality, modular services can be easily reused in various contexts and also can be composed to satisfy new requirements. On the other hand, modularity...
The aim of this work is to present audience with a motivation for research aimed at introducing a new approach towards a Web service description. The description is referenced mainly at Service Oriented Architecture oriented enterprises, as they are the most plausible candidates for its employment. Nevertheless, one might perceive it as a proposition of changes that could have wider reception. The...
Business automation continues to be a strategic target for IT investment. However, business automation involves inherent challenges, such as system integration issues. Service-Oriented Architecture (SOA) and business-to-business (B2B) integration standards are two approaches used for creating business automation solutions. In this paper a systematic literature analysis is conducted to explore the...
Service oriented architecture (SOA) promotes highly standardized, loosely coupled and Web-enabled services to foster rapid, low-cost and easy composition of distribute applications. Critical to SOA software development is to acquire users' requirements and to provide service analysis and design techniques for identifying, conceptualizing, profiling, and rationalising service-enable applications. Semantic-enabled...
The combination of BPM&SOA has been considered a powerful strategy for companies to be more agile. However, integrating BPM and SOA has many challenges especially when composition of applications is envisaged. The main contribution of this work is to propose an integrated model that deals with the problem of service discovery over largely distributed software services providers, including QoS...
Service Oriented Architectures (SOA) and Web services (WS) are important for creating interoperable information systems. However, these technologies lack of semantics. To overcome this limitation, semantic Web services are necessary. In this paper we present a synthesis of some recent works we estimate interesting in the field of semantic interoperability via Web services. We first present some conceptual...
In health informatics there is no such mechanism of binding healthcare service providers and requesters that provide publish and retrieval of healthcare services. Healthcare web services should be published with formalized semantic descriptions in a structured and uniform way, to automate healthcare service discovery. The use of semantic web technologies and service oriented computing for efficient...
In this paper, we proposed a framework integrated Semantic SOA (Service-Oriented Architecture) and Workflow to solve the problem of enterprise application rebuilding, and described the function of the main units of the framework. At last, we discussed the aspects of the future studies that we will address.
