Architecture description languages (ADLs) play an important role in specifying the software architectures. While most of these ADLs are unable to deal with the change directly, especially for dynamic evolution of software systems. This paper proposes an XML-based ADL, named Breeze/ADL, which is supported by Breeze Graph Grammar (BGG) - a graph grammar we defined, to describe software architecture...
Considering certain inadequacies of the existing user interface generation technology under cloud computing environment, we propose a new software architecture for generating user interface dynamically, which has the characteristics of cross-platform, scalable, generating the personalized user interface dynamically. And the instance has demonstrated that the architecture is effective and feasible...
For the purpose of high reliability and low cost when distributed computing system is developed, an architecture description language based on software reliability evaluation for distributed computing systems (REAL) is proposed in this paper. Its main purpose is used to describe the software architecture of distributed computing system in order to evaluation reliability of a given architecture. It...
The loosely-coupled and dynamic nature of web services architectures has many benefits, but also leads to an increased vulnerability to denial of service attacks. While many papers have surveyed and described these vulnerabilities, they are often theoretical and lack experimental data to validate them, and assume an obsolete state of web services technologies. This paper describes experiments involving...
Large scale Service Oriented Architecture (SOA) developments are becoming increasingly reliant on registry services that manage Web Services using taxonomic attributes. At present a registry stores a Web Services interface definition and protocol bindings in WSDL, along with one or more XML schema files that define the structure of a SOAP message exchanged between Web Services operations and client...
The paper analyzes the deficiency of the existed legal risk management system and puts forward a new solution of legal risk service system based on Service-Oriented Architecture (SOA). We propose a service oriented legal risk service system frame and expatiate methods and steps of integration based on SOA detailedly. Conclusively,the solution of based on SOA is feasibility and superiority developed...
The paper designs and develops a platform for automatic generation of dynamic website by using XML technology. And the paper researches the system architecture and function, expounds the key technique of the template and tag library. Finally, the advantages of platform are discussed and the outlook is made.
Current theories and systems do not satisfy the requirements of P2P streaming on Internet in aspects of large scale, high quality and low cost. The transmission model of overlay network is the key factor. This paper proposes Regular Structured Model for P2P streaming including overlay network theory and management mechanisms. We developed ClusterStream a high service quality streaming system based...
Service-oriented Architecture (SOA) is increasingly relevant across several domains of application by promising systems openness and unification over a common design and communication paradigm. At device level, the application of SOA is carried, on one hand, by Devices Profile for Web Services (DPWS) and complementary web-based specifications oriented towards resource management, and, on the other...
The steady drumbeat of Cloud as a disruptive influence for Infrastructure Service Providers (ISP's) and the enablement vehicle for Software As A Service (SAAS)providers can be heard loud and clear in the industry today. In fact, Cloud is probably at the peak of the hype curve, and already there are identified challenges associated with effective deployment for business critical applications (so called...
The geographical knowledge-informed digital gazetteer service (KIDGS) is a standard web service that provides unified XML-based access interfaces for various applications. In order to solve the problem of the raising data storage crabbed from millions of web pages and increasing query efficiency requirements for different levels of requests, we analyze the characteristics of cloud computing application...
In a Sensor Web environment, sensors are heterogeneous. The Sensor planning service offers a standardized interface for the control of sensors and simulations. But some complex sensors like satellite need midterm or long-term action to response a given task, so, adding asynchronous support in SPS is necessary. The workflow description language can chain asynchronous web service together while it has...
IELS, which abbreviates Interactive English Learning System, is a computer assisted pronunciation training (CAPT) system for Chinese learners of English whose mother language is Mandarin. The system provides instant feedback of mispronunciations of phoneme, word, lexical stress, and a score of the student's overall pronunciation quality. The system employs client-server architecture, in which the...
Aiming at the tight coupling features between system and modules in the distributed application system that implemented with components, the paper brought out an Event Process Framework (EPF), which achieves information interaction among systems in the manner of event processing. The event process mechanism referred to information interaction manner of High Level Architecture (HLA) in distributed...
To address the serious problems in e-commerce based on traditional 2D image-word, the author introduced Web3D, Flex and SSH technologies into e-commerce, presented “3D Virtual Reality & Flex” Web architecture for e-commerce, researched mechanisms of their architectures, and implemented their integration and communication & interaction: Flex and Struts2 via XML, Flex and Spring & Hibernate...
For Global Service-Oriented Architecture (GSOA), we need to make sure that the Web Services provided by the service providers are visible to all potential consumers across the globe. In this paper, we discuss about Universal Description Discovery and Integration (UDDI) and its limitations as public repository. For this, we propose using Really Simple Syndication (RSS) as a repository. RSS is indeed...
Average information workers spend most of their time for searching, analyzing, reformatting and consolidating information. The recent advent of service-oriented architectures (SOA) built on Web services is a first attempt to streamline respectively automate those tasks in order to increase productivity. SOAP-based services work well within a company and are thus mainly used to for the integration...
A remote laboratory aims to provide access to remote lab equipment over the internet. The design and development of the client software is subject to various requirements. In this paper we discuss these requirements and propose solutions. Implementations are demonstrated for some remote experiments developed in the ERRL project. An XML format for experimental results is proposed as an attempt towards...
Spatial data exchange and system interoperate have become crucial technologies in land resources informatization. Due to the land resources data is accessed using a variety of GIS platforms, and the management systems are developed by different development languages, the data exchange model must support platform-independent solutions implemented in distributed heterogeneous environments. This paper...
As the internet developing, web-based applications are increasingly popular in service-oriented architecture. Web service has XML support, which is the most suitable technology to achieve service-oriented architecture. Web service is essentially an interface which enables the isolations between different sites to communicate with each other. In this paper, based on .NET platform for web service and...
