Semantic web service is proposed to support the automation of service discovery, composition and invocation. However, it is still difficult for common users to compose semantic web services or generate them from web services. In order to alleviate such pains, in this paper we present Flow Editor: a visual semantic web service composition tool based on OWL-S specification. It has several advantages,...
Web services technology is mainly designed for the interoperability among machines, whose inputs and outputs are defined in the form of XML schema without presentation information, hence it is unable to present the execution results of Web services to human beings directly and friendly. To address this problem, an ontology-based method and a rendering engine are proposed in this paper. In the method,...
The functional requirements of multiple tenants are supported by a single instance in a SaaS System, but the differences between tenants make it difficult to unify in same business logic. Based on the construction of SOA and using BPEL to deploy different processes on application servers, a business process customization model for the application layer is proposed and the specific solution of process...
The features and application ranges of several database design proposals applied in SaaS are discussed. Based on shared database / shared framework, three relationship-based extension models which are custom field, pre-allocation field and name-value pairs and XML-based extension model are discussed and the latter implementation approach in data definition, query and update is also given, along with...
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...
To prevent file transmission in the electronic military affair system from being damaged. Methods: security mechanisms of Web service based on J2EE platform, system security based on RSA algorithm, and the basic principle of digital signature. Procedure: to explain definition, characteristics and structure of the electronic military affair system, and to analyze its design process and security. Conclusion:...
An open resource-based integrated platform system is built for the execution of business processes, assuming that the business process model is the fundamental factor for the next generation of integrated business information systems. First of all a resource meta-model is constructed, which represents the basic information unit. Then the concept of domain ontology is used to organize and manage resources...
Currently there are increasing interests in using REST architecture style to implement business process. However, the importance of role is not emphasized. In fact role is critical to determine the RESTful services description and to control the services composition. This paper presents a role-centric RESTful services description and composition mechanism to implement business process. Firstly a resource...
This paper describes the design and implementation of a geographical knowledge-informed digital gazetteer service, KIDGS. It is a standard web service that provides unified XML-based access interfaces for various applications. At present, many digital gazetteer systems are implemented directly based on relational databases. In other words, place name entries are managed by data tables. However, several...
Managing and monitoring a cluster is both a tedious and challenging task, since each computing node is designed as a stand-alone system rather than a part of a parallel architecture. In this paper, a software system that allows the centralized administration of a generic Beowulf cluster is proposed. This system also provides Web services and applications to monitor multiple PC clusters with job submission...
