An architecture model for dynamically converting components into Web services

Components are the basic building blocks of enterprise and distributed applications. Component-based development (CBD) is the technique of using a component framework to develop components and it focuses on developing large software systems by integrating previously existing software components. Component oriented architecture has already being developed by which components may be developed, assembled, stored and reused. It is possible to assemble an application from a repository of components developed in various languages by homogeneous or heterogeneous composition. Web services represent an evolution of the Web to allow the open and flexible interaction of applications over the Internet. Web services standards provide a high level of interoperability across platforms, programming languages and applications and hence these facets of Web services have been used to integrate the best aspects of component-based development and the Web. In this paper we propose a new method for integrating Java and C++ components by dynamically converting them into Web services using AXIS and gSOAP respectively.

A model for application integration using Web services

The history of computing has seen several interesting trends. From a programmer building custom packaged applications to the development of enterprise resource planning (ERP) systems, and other business specific packages. The need for integrating different systems in the organization led to point to point interface and spaghetti architecture. Fallout of these spaghetti architectures is the development of the enterprise application integration (EAI) concept. In this paper we are going to discuss the evolution of EAI concepts and a new architecture for event driven data transformation for application integration using Web services. The new architecture overcomes the drawback of request-reply semantics of Web services by providing an event driven architecture, which supports asynchronous communication between applications using Web services. We have also implemented a secure framework for accessing third party Web services using message level encryption and digital certificates.

A framework for dynamically converting components to Web services

Components are the basic building blocks of enterprise and distributed applications. Component-based development (CBD) is the technique of using a component framework to develop components and it focuses on developing large software systems by integrating previously existing software components. Software development based on component based architecture is already in wide use throughout the software industry. Component based development makes it possible to assemble an application from a repository of components developed in various languages by homogeneous or heterogeneous composition. Web services provide an easy way to extend component based development by adopting open Internet standards. Web services represent an evolution of the Web to allow the open and flexible interaction of applications over the Internet. Web services standards provide a high level of interoperability across platforms, programming languages and applications. In our current research we have created a model for automatically converting components created in different languages to Web services. The components that are developed in various languages are deployed dynamically (just in time) in the Web servers by using custom built deployers. Using this model the users can access the components that reside in the server using open Internet standards, without having to worry about the language and platform restrictions. The security aspects to access the Web services were also considered while implementing the model.

Automatic translation form requirements model into use cases modeling on UML

Given the investment organizationsare making in use cases and the increasing use of computers to control safety-critical applications, the research on integrating use cases and safety consideration is highly demanded. However, currently the approaches for incorporating safety analysis into use case modeling are scarce. In this paper, we present an approach to integrating safety requirements into use case modeling. We demonstrate how deductive and inductive safety techniques can be used hand-in-hand with use cases. An application of the proposed approach facilitates early hazard identification and assessment, as well as elicitation and tracing of safety requirement though the entire development process. The proposed approach is illustrated by a realistic case study – a liquid handling workstation.

Convergence agent model for developing u-healthcare systems

Ubiquitous networking, the interlinking of computers, consumer electronics, automobiles, home appliances, medical equipment, transportation systems, animals and plants through an overlapping of electronic spaces and physical spaces, is expected to provide an environment that enhances our lives through improved convenience, efficiency and safety in all areas. Todays healthcare industry emphasizes safety, efficiency, patient-oriented approach, timeliness and balance. u-healthcare makes it possible to safely deliver appropriate services from any location at any time. To explain the emergence of u-healthcare, one must invoke, first of all, progress in IT and medical technology, and then the desire and willingness on the part of health care institutions to adopt the new service concept and increased health care demand. Digitalization of information, introduction of broadband communication and leaps made in healthcare technology in recent years have provided the technological capacity necessary for the achievement of u-healthcare. Based on recently reached theoretical results, integrating u-healthcare environments in virtual organizations, we proposed a methodology for the design and implementation of u-healthcare, linking the distributed mobile agents with medical entities into a convergence and collaborative environment. Despite the challenges in implementing and deploying u-healthcare, the advantages of ubiquitous healthcare are enabled by our smart model for the soft computing endowed ubiquitous. The strength of our approach is that it relates to u-healthcare a system which consists of its dual character emerging from the synergetic interaction between ubiquitous computing techniques and the mobile devices in convergence manner. We have developed a set of initial healthcare agent services on the mobile collaboration framework. We evaluate the functionality and effectiveness of our convergence mobile agent, whether the platform can manage services based on the model and whether the results of u-healthcare services discovery could satisfy users requirements with example cases.

Web Service Security model Using CBD Architecture

A Web services is programmable application logic accessible using standard Internet protocols. Web services combine the best aspects of component based development and the Web. like components, Web services represent black-box functionality that can be reused without knowing about how the service is implemented. Unlike current component technologies, Web services are not accessed via object-model-specific protocol. In this paper, we suggest the architecture development modeling and the Web integration architecture to develop Web service-security that is embodied in supplier on service oriented architecture (SOA). We also describe the various possibilities with which the components may be integrated well with applications have been explored and well-exposed using Web services. This paper focuses on integrating component based architecture modeling and Web services to enable the development and usage of facade and backside components through the Web by dynamically creating Web services-security for the functionalities of the components.

Reliability Assurance in Development Process for TOE on the Common Criteria

Security begins with good software code and high quality testing of the code, and it continues with the process used to identify corrected and patch security vulnerabilities and with their auditing based on recognized standards. Security is an important aspect of software systems, especially for distributed security- sensitive systems. The Common Criteria (CC) is the standard requirements catalogue for the evaluation of security critical systems. Using the CC, a large number of security requirements on the system itself and on the system development can be defined. However, the CC does not give methodological process support. In this paper, we show how integrate security aspects into the software engineering process. In addition, we also introduce our work on ensuring the reliability assurance in development process for Network Management System as TOE. The activities and documents from the Common Criteria are tightly intertwined with the system development, which improves the quality of the developed system and reduces the additional cost and effort due to high security requirements.

CAS4UA: a context-aware service system based on workflow model for ubiquitous agriculture

Practical automation in agriculture can save the time of the cultivation and increased the productivity. Generally, because agricultural environment is very changeable, the natural elements has to be considered in the autonomic cultivation process. Recently, the workflow model has been used as an effectual service automation model in traditional business environment, Web service environment, and ubiquitous computing environment. This paper proposes CAS4UA, which is a context-aware service system based on a workflow model for agriculture. The suggested system uses a workflow model to offer an automatic and context-aware service for ubiquitous agriculture, and to support the ubiquitous agriculture based on USN/RFID. To do this, the system uses a workflow model including various agricultural context information. Through the workflow model, the suggested system can dynamically and automatically control a service flow according to the changeable conditions in agricultural environment. Therefore, the proposed system can be useful in developing a smart service or automating work processes for ubiquitous agriculture.
