Considering the current situation of the data on oil and gas resources in China, which is relatively multi-sourced, heterogeneous and decentralized, as well as the actual demand of OLAP, MVC model is employed as the system constructing model. Besides, ODBC and XML technology are combined to achieve dynamic mapping on database connection. Thus the National Petroleum Resource Database ETL System which...
Along with the infiltration of wireless sensor network in every field of our life, sharing sensor network resources in Internet environment is one of key problems which must be solved by wireless sensor network application. This paper expounds Web Service technology and uses Web Service technical framework for reference to design a new kind of service-oriented sensor network structure. And finally,...
SOA is a new kind of architecture design for system development. It can solve heterogeneous problem by decomposing software services module and integrating service module. Traditional logistics information system has poor scalability and reusability, it is easy to form information islands. E-business logistics information system based SOA provide an ideal framework for design and implementation of...
This The production and operation management system using SOA design and implement, which bases on the service-oriented development idea, enhances the company's core competencies, and put coupling loosely, high reusability and agility into effect really.
Among many service choreography description languages, WS-CDL which has been developed by W3C is the most popular one. This language is an intermediate language mostly considered as a design language to describe the choreography, and is unable to model the choreography in high level. Regard to this issue, this paper proposes a set of notations, used at the analysis phase, help user to express the...
Within service orientation (SO) web services (WS) are the defacto standard for implementing service-oriented systems. While consumers of WS want to get uninterrupted and reliable service from the service providers WS providers can not always provide services in the expected level due to faults and failures in the system. As a result the fault management of these systems is becoming crucial. This work...
With the widespread of Web services (WS), more deployed services are being registered into a services registry, consequently giving rise to a series of problems. A conspicuous one is the large amount of functionally equivalent Web services returned by a service registry. A plausible solution is to involve QoS (quality of service) in the services discovery. However, some existing QoS-based discovery...
This paper presents the digital high-definition television (HDTV) receiver for the ISDB system. It receives 8 phase shift keying (8-PSK) satellite broadcast and orthogonal frequency division multiplex (OFDM) terrestrial broadcast. It decodes the MPEG2 audio/video stream and converts the original HDTV picture to the various display formats. It also decodes the interactive data broadcast content written...
Mass spectrometry is the work-horse technology of the emerging field of metabolomics. Community-wide accepted data models and XML formats for data interchange such as mzData are currently in development. The information contained in these models is sufficient to create applications and databases in a model driven architecture (MDA). This allows to (re-)create the necessary code basis and backend database...
Existing template languages and engines do not give guarantees about the results of the instantiation process. As this is a possible source of errors and the reason for additional testing efforts, the proposed architecture that allows guarantees about the instantiated template will increase the quality of applications incorporating template engines, like Web Content Management Systems and UML tools...
Web services are increasingly used to enable interoperability and flexible integration of e-business systems. In this paper we focus on measurement-based performance analysis of an e-commerce application which uses Web services components to execute business operations. In our experiments we use a session-oriented workload generated by a tool developed accordingly to the TPC-W specification. The empirical...
Since business logic is complex and changes frequently, e-business software architecture becomes more complex and difficult to maintain. From the perspective of software architecture design, this paper proposes a temporal ECA based architecture for e-business systems (TECAB) representing business logic in the form of temporal ECA, sketches a conflict-managing mechanism based on meta-action. The TECAB...
