The transactions in SOA running across multiple services over multiple domains, which will be alive for minutes, hours, even days depending upon the underlying business requirements and implementation, and they used synchronous mechanism to maintain business integrity. Application's performance is seriously hampered because of locking up resources for a long time which is caused by synchronous interaction...
With the development and popularization of Internet, distance education has already entered the stage based on Web. Due to the shortcomings of traditional methods in developing Web application, the MVC (model-view-controller) pattern is introduced. The separation of logic programming from interface design is effectively archived by the three kinds of technology correlated with Java: JSP, Servlet and...
This paper introduces the service-oriented architecture (SOA) and grid technology. SOA has the characteristic of loose coupling, easy to realize cross-application integration and achieve the complete separation of business and technology. Grid technology has the ability of using the geographical distribution resources on the Internet, provides users with information and application integration services...
The competition in international commercial activities, especially in retailing and mechanical trades, is increasingly intense. In such a situation, there is not any wiser choice than the Global E-procurement system. However, large numbers of domestic enterprises encounter various problems when dealing with the system. So in this paper, a systematic solution to the E-procurement platform is presented...
Service-Oriented Architectures (SOAs) have become an important cornerstone of the development of enterprise-scale software applications. Although a range of domain-specific languages and standards are available for dealing with such architectures, model-driven approaches starting from models written in an established modelling language like UML and including the ability for model transformation (in...
This paper describes the development of a Research Infrastructure to support research in the area of logistics. This infrastructure is a computer aided research platform that is based on the Institute's Logistics Paradigm. This infrastructure has been, through a process of model enactment, implemented using a 3-tier architecture using J2EE. The process of model enactment is described, using the survey...
This paper analyzes the structure of Java-based Agent development framework JADE. Based on the traditional consultative mechanism, give the model of consultation for single-to-many projects. In the true sense, the logic model establishment of the e-commerce consultation, and this makes the third party e-commerce platform get higher autonomy and intelligent.
This paper describes a benchmarking workload model for business process execution language (BPEL) engines for Web services. The proposed model is based on simulation of real world traffic conditions by defining a set of requirements which best characterize the end-users. The performance characteristics are evaluated on top of collected measurements such as success/fail rate, response times or round-trip...
SBVR is a new standard that defines a metamodel for business-layer vocabularies and rules. This paper summarizes SBVR features and argues that the SBVR enables definition of true ontologies. The paper also summarizes experience with a partial SBVR implementation in the context of an existing technique for modeling businesses and transforming the models into implementations. The work contributes to...
The trend over the past decade in computer science and computer engineering curricula has been to use computer graphics as a junior- or senior-level elective course focusing on 3-D graphics and data visualization. Alternatively, it is possible to develop a computer graphics course that can address core curricular needs beyond its obvious topical and algorithmic scope. The development of an interactive...
