  • As the nature of the embedded system, it is operated by user specified requirements, the dynamic action(behavior) is needed when the user's requirements change or unexpected situations occur. In this paper, it is proposed that design and implementation of SOA(Service-oriented architecture) based S/W services for dynamic behavior of embedded System. In this proposed technique, the status of embedded system can be checked through Web services, and in the cases of exceptional situations, the required proper actions can be newly updated through Web services. Through this technique, the burden of users concerning exceptional situations can be reduced, and the convenience of use can increased as well.

  • In order for companies to survive rapidly changing business environment, it is expected that the activities in an enterprise must be reorganized around business processes; the information infrastructures are based on Web Services; and information systems are re-built around the BPMS (Business Process Management System). In this research we suggest major directions of e-business enhancement especially based on SOA(Service Oriented Architecture). Then we investigate the correlation between BPM functionalities and e-business technologies, and suggest priorities among the evolving directions of BPM functionalities via an intensive expert survey. The results of this study can be used by BPM solution vendors, prospective buyers and IT policy makers.

  • Today, businesses have to respond with flexibility and speed to ever-changing customer demand and market opportunities. Service-oriented architecture (SOA) is the best methodology for minimizing the complexity and the cost of enterprise-level infrastructure and for maximizing the productivity and the flexibility of an enterprise. Most of the enterprise-level SOA delivery strategies deal with the top-down approach, which organization has to define the business processes, to model business services, and to find the required services or to develop new services. However, a lot of peoples want to maximally reuse legacy component-based systems as well as to deliver SOA into their organizations. In this paper, we propose a bottom-up approach for identifying business services with proper granularity. It can improve the reusability and maintenance of services by considering not data I/O of components of legacy applications but GUI event patterns. Our proposed method is applied to MIS with 129 GUIs and 13 components. As a result, the valiance of the coupling value of components is increased five times and three business services are distinctly exposed. It also provides a 49% improvement in reducing the relationship problems between services over a service identification method using only partitioning information of components.

  • Most of the SOA solutions applicable to businesses and organizations are taking a top-down methodology. It starts with an analysis of an organization's requirements, followed by definition of business models and identification of candidate services and ends with finding or developing required services. Challenges in adopting SOA while abandoning legacy systems involve time and cost required during the process. Many businesses and organizations want to gradually migrate into SOA while making the most of the existing system. In this paper, we propose A Method for Migration of Legacy System into Web Service(M-LSWS); it allows legacy system to be migrated into web service accessible by SOA and be used as data repositories. M-LSWS defines procedures for migration into reusable web services through analysis of business processes and identification of candidate services based on design specification and code of legacy system. M-LSWS aims to migrate of legacy system into web service appropriate for SOA. The proposed method consists of four steps: analysis of legacy system, elicitation of reusable service and its specification, service wrapping and service registration. Each step has its own process and guideline. The eligibility of the proposed method will be tested by applying the method to book management system.

  • In this paper, we propose the application models and strategies of geospatial services registries for SOA in GIS web services. Recently. a number of SOA/web services are being developed for various commercial or public applications. However, geospatial SOA services are less used than general purpose SOA services, because GeoSpatial service registries has been neglected in many GIS applications even though GeoSpatial registries are essential component for open geospatial services. These problems are due to lack of researches for GIS registry usages. In this paper, we define the role player ill GIS SOAs, and develop the various GIS web service models among the players. Besides, we suggest the applications strategies of GeoSpatial services registries in the service models.

  • As software systems become more complex and larger, software systems require a way to reuse software components or modules to provide new functionality. This paper designed a development method of web system combining SOA(Service Oriented Architecture) with MPSL(Multi-Software Product Line). According to provides SOA and MPSL, this paper suggested to service providers and service users to provide and reuse variable services. From the viewpoint of service provider, the suggested method identifies and implements reusable variable services as features by syntax-based, functional-based, and behavior-based methods applying feature identification guidelines and manages them as reuse assets. From the user's point of view, it is possible to develop a web system by constructing a service by workflow model as a method of structure and reconfigure services. As a result of measuring the reuse of the web system constructed in this paper by the function point, the cost reduction effect was verified by applying it to the similar project with the increase of reuse.

  • Web service should be to connect business between enterprise through the Internet, promotion of construction speed and decrease of development expense of service construction are possible. Also, unification with other domain is possible easily, and update or correction is easy by offering reusability and replaceability through component based development. In this paper, We suggest development process to build architecture and this to integrate consisted component efficiently to develop web service that is embodied in supplier side on service oriented architecture(SOA). The suggest architecture to integrate component that is consisted for this efficiently, and describes development process. So that component develops web service to base structure of web service because do command stratification logically function in each hierarchy define, and presents architecture based on logical hierarchy. The web services consist of Facade and Backside component; The Facade component have web service functions. We describe process that develop to Facade component and present mailing web services as case study. It can be decrease production cost and development time. The web service based on component will improve reliability for reuseability and replaceability.

  • Recently, a combination of Business Process Management (BPM) and Service Oriented Architecture (SOA) is being recommended as the best approach for automating large business systems. And the need to create meaningful information from daily operational data is increased today. In this paper, we propose a methodology for automating business processes based on the BPM-SOA convergence trend and verify the methodology by implementing the project management business process. BPM-SOA convergence provides higher extensibility and productivity due to the loosely coupled system construction and maintenance. The system has good properties for frequent process changes and reuse of duplicate processes. We then analyze extensibility of the system as new business processes are added to the existing system. We finally analyze the data generated by BPM by using SAP business intelligence to support management's decision making and strategy. Business intelligence provides not only useful data for business decisions but also chance to optimize the business processes.
