In enterprises using service-oriented architecture (SOA) architectural information is used for various activities including analysis, design, governance, and quality assurance. Architectural information is created, stored and maintained in various locations like enterprise architecture management tools, design tools, text documents, and service registries/repositories. Capturing and maintaining this...
Service evolution is a critical issue because even small changes, if not compatible, can potentially affect a huge number of client applications. However, particularly in the context of large scale service usage, changes have different impact on clients according to its use. This paper proposes a change management framework that supports service providers to scope and quantify the impact of changes...
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, it has been analyzed for risk factors and control framework. The technology of the risk control system of social medical insurance is studied. The system adopts SOA, active data warehouse and data mining technology, and is based on model base, method base and rule base of risk control of medical insurance fund. The system will realize real-time data exaction, massive data integration...
HealthGrids represent the next generation of advanced healthcare IT and hold the promise to untangle complex healthcare-data problems by integrating health information systems and healthcare entities. Healthcare could benefit from a new delivery approach using HealthGrids to better meet the biomedical and health-related needs. Specialized services are needed to provide unified discovery of and ubiquitous...
Aiming at the requirements in the process of building a SOA application system, such as dynamic service deployment, service finding and reference, the demand for adaptability to change and system scalability, this paper introduces the characteristics and drawbacks of service-oriented architecture, describes the theory about OSGi and its advantages. Through the combination of SOA with OSGi, a dynamic...
Abstract-Traditional EA concepts in the Enterprise Application Integration (EAI) domain focus on ex-post integration of application interfaces by pipelining different middleware technologies like message queuing or remote method invocations [1, 2]. Web Service enabled Service-Oriented Architectures (SOAs) used in the EAI context were a step towards providing an abstraction layer for the involved interfaces...
Recently with the rapid growth of network and changes of business environment, the enterprises require the integration of various information systems and their interoperation. The SOA (service oriented architecture) based on Web services is widely used for integration of these information systems. And as the standard integration language for the business processes, BPEL (business process execution...
The existing e-campus management system continues to develop intensely driving the service requirements towards a deep application base in data sharing and operation cooperation. The article introduces SOA technology and the superiority of composing services according to the requirements of an information system. This article also brings forward the architecture and construction of the e-campus management...
To support legacy migration to service-oriented architecture (SOA), this paper presents a method that derives candidates of SOA services from procedural programs. In SOA, every service is supposed to be a process (procedure) with (1) open interface, (2) self-containedness, (3) coarse granularity for business. We identify such services from the source code and its data flow diagram (DFD), by analyzing...
SOA have been deployed as a mean to offer a better flexibility, to increase efficiency through reuse of services and also to improve interoperability by providing new opportunities to connect heterogeneous platforms. However, those benefits make security more difficult to control. Fortunately, new standards are proposed to treat this issue, but their current use makes the architecture much more complex...
As is known to all, the shortcomings of traditional SOAP-based Web service and the older XML-RPC protocols, such as lacking of addressability and connectedness, greatly limit the modeling and abstraction of enterprise resources. In order to integrate the resources of enterprise information systems in heterogeneous environment, this paper proposes a REST-based resource-oriented approach to integrate...
More and more Web services are emerging in the Internet with development of service computing over the past decade. The web service in SOA system naturally forms into some service community during execution process. Mining and analysis Web service community will help design SOA system and support Web service application effectively. This article addresses the problem of how to discovering Web services...
The characteristics of airlines IT architecture are summarized in this paper, also analyzed are the rigid challenges facing the IT and business in the profoundly changing business environment of the air industry. Upon the standpoint that the key of the IT value is to pursue business sustainable innovation and flexible agility with composite applications under flexible IT architecture, are designed...
The execution of process-oriented composite services described with BPMN has become a hot research topic. In this paper, we present a decentralized execution engine for BPMN-based composite services, the basic idea of which is to make a BPMN model directly executable without converting to another executable model. An executable BPMN model named BPD is first defined. Second, a set of algorithms are...
Implementing a workflow using previously implemented services is a typical task while dealing with Service-oriented Architectures (SOA). Defining these workflows is the task of business (process) analysts in tight collaboration with clients or domain experts. Unfortunately these analysts only have a sketchy view on the Service-oriented Architecture, thus they do not know which investigations a specific...
Declared `dead' for quite a while now, many legacy mainframe applications are still happily productive and will continue to be. Within them mainframe database management systems like Adabas or IMS are utilized as well as related programming languages like Natural or COBOL. However, those applications are often only badly, if at all, integrated with newer enterprise applications. This article describes...
Growing number of reports on the problems with SOA projects indicates that SOA faces substantial problems. It can be a consequence of the fact that SOA passes the disgustion phase of the hypo curve. It, however, must have some concrete reasons. We analyze frequently used and often even recommended SOA development practices and processes and we show that the processes implicitly apply few known and...
The success of the user generated content raises the new idea of enabling end-users to create their own services. User generated service will become the next big user-driven hype in the technology arena. This paper presents an overall view of the user generated service, from both technical and business perspective. We clarify the concept of user generated service, analysis the challenges, and illustrate...
The tendency of manufacturing execution system (MES) is service-oriented and reconfigurable and this paper researches the reconfigurability of service-oriented MES. It analyzes MES reconfigurability by making a reference to CIM-OSA and proposes three views, including function reconfigurability, data reconfigurability and process reconfigurability. Service-oriented MES is designed in a multi-tier architecture...
