To solve the problem existing in the traditional centralized workflow systemsuch as poor scalability and strong coupling between process management and business application, we present the architectural design of a distributed multi-engine workflow system based on web services. The separation of the process logic implementation and the application logic implementation improves the flexibility and...
Web Services are built on service-oriented architecture which is based on the notion of building applications by discovering and orchestrating services available on the web. In order to make an orchestrated web service, which is a composition of two or more services, resilient to transient faults, we investigate in this paper the idea of applying checkpointing to web services. We propose a checkpointing...
This paper reviews three kinds of information exchanging technology in the distributed computing environment, and introduces message-oriented middleware to implement the integration of todo-list distributed in the different business applications. Based on the analysis of the architecture and implementation framework of message-oriented middleware, the paper discusses the enterprise application integration...
The current focus of enterprises on automating processes has led to the extensive application of workflow management systems. It has previously been difficult to integrate traditional workflow management systems with other types of systems, but the rapid development of Web services has solved communication problems between heterogeneous platforms and allowed for the efficient integration of legacy...
In recent years, web technologies as well as XML have gained broad application throughout the industry. Web services have become increasingly important for network application solutions since the business processes are no longer constrained by company-related boundaries by the use of web services. In order to avoid the considerable mass of repeated time consuming hand coding at low-level, a SQL-based...
Web services have been widely accepted as a platform-independent services-oriented technology. On the other hand, ubiquitous technologies are getting popular in a variety of domain applications. In particular, hosting web services from mobile devices became a way of extending knowledge sharing for teaching and learning purposes. This paper presents our design and implementation of a mobile web services...
Internet contains a tremendous amount of valuable web applications that can be used in many systems. To use this kind of applications with other systems, the interaction needs to be in a standard structured format such as XML web service. In this paper, we present a method to convert the current web applications into standard XML web services. The system design and implementation are presented. We...
This paper describes an e-banking system designed for both mobile handhelds and regular computers. This system demonstrates how to bring together and generalize online services, such as e-banking, e-auctions and e-shopping. That is why the system exposes its services over HTTP in both HTML, targeting common web browsers, and XML (i.e. web services), targeting mainly, but not only, mobile devices....
In order to explicate the applicability of importing Web Service to digital library information retrieval system, this paper firstly briefly introduces Web Service. Then the authors construct an information retrieval model based on Web Service to improve the current retrieval system. In this paper, we comprehensively present the model from overall designing, process designing, interface implementation...
Isolate and redundant Cost information in the project manufacturing life-cycle hinder overall system cost information integration. In view of the above problem, this paper use SOA theory combined with Web Service to design a cost information integration system framework and platform for project manufacturing enterprise. Cost collector is introduced to project manufacturing for gathering the cost information...
This paper made an exposition of the mobile search servicing system's demand, architecture, main functions of components according to a case for searching a place of entertainment of a city. It specially elaborated on how to use mobile context and policy management to render web services for mobile web service middleware.
Nowadays manufacturers face the great challenges of a worldwide market, collaborative environments and the method of management of the whole product life cycle. Accordingly, a web based platform is proposed for collaborative designing and agile manufacturing. Without face to face discussion and specific CAD/CAM system, manufacturers and designers work for a component with the platform. For the purposes,...
Current manufacturing applications demand the design of more and more complex, safe and trustworthy control systems which exhibit a high degree of flexibility and reutilization. The present work deals with the use of Web Services and databases to support the design and development of manufacturing systems, with special emphasis on incorporating reuse. This approach has been proposed in the context...
This article describes and analyses the current situation about data integration of isomerous data platform, and puts forward isomerous data integration plan based on the adapter. In the article, I adopted the adapter technology to realize isomerous data exchange model, and enveloped the adapter function in Web service in order to dispose the adapter by the distributed computing way. The goal of isomerous...
Middleware has become the popular runtime infrastructure of modern IT systems. Due to the complex application contexts and various user requirements, more and more applications are now making use of different middleware platforms. It might require the cooperation of several types of middleware, and result in challenging issues for collaborative management of heterogeneous middleware. To solve this...
The online declaration system of university student's scientific research project has avoided the waste on traditional manpower and resource, improved interaction between teachers and classmates. Its status will be more and more important with the enthusiasm which students participate in the scientific research. This paper presents the design and realization of an online declaration system in detail...
Surface acoustic wave (SAW) gas sensors based on PANI (polyaniline) is studied experimentally and theoretically to overcome the Low sensitivity, high working temperature and high cost of the traditional CO gas sensors. The sensor networks system required that sensors have some function of Grid computing. In this paper, we discuss a model for interfacing sensors to grid computing and show how to use...
Aimed for the problems of strong coupling and poor scalability between centralized workflow system and business application system, a workflow platform based on web service was presented, which separated the business data and the workflow data, supported the access of new business system, improved the reusability of workflow system. The web services used to interact with workflow platform were designed...
The cooperation between the Brazilian and Chinese governments established in 1988 led to the development of imaging satellites, which help monitor the natural resources of both countries. In Brazil, the CBERS program includes a policy of free distribution of the images, first inside the national territory and, more recently, to other countries. This distribution is done through a catalogue available...
Learning Management Systems (LMSs) are more important in e-learning and future education. LMSs provide a set of functionalities and educational services to manage learners and learning contents. With the Internet growth, various learning contents and different learning systems are distributed independently. Thus, managing the distributed information and implementing interoperability between learning...
