In this paper, we have made the component-based development of observational software for KASI solar imaging spectrograph (KSIS) that is able to obtain three-dimensional imaging spectrograms by using a scanning mirror in front of the spectrograph slit. Since 2002, the KASI solar spectrograph has been successfully operated to observe solar spectra for a given slit region as well as to inspect the response functions of narrow band filters. To improve its capability, we have developed the KSIS that can perform sequential observations of solar spectra by simultaneously controlling the scanning mirror and the CCD camera via Visual C++. Main task of this paper is to introduce the development of the component-based software for KSIS. Each component of the software is reusable on the level of executable file instead of source code because the software was developed by using CBD (component-based development) methodology. The main advantage of such a component-based software is that key components such as image processing component and display component can be applied to other similar observational software without any modifications. Using this software, we have successfully obtained solar imaging spectra of an active region (AR 10708) including a small sunspot. Finally, we present solar $H{\alpha}$ spectra ($6562.81{\AA}$) that were obtained at an active region and a quiet region in order to confirm the validity of the developed KSIS and its software.

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, large-scale enterprise information systems are commonly based on the multi-tiered middleware or frameworks to support such requirements as functional reuse, heterogeneous system resources, and multiple platforms. However, these multi-tiered or distributed multi-platform architecture incurs the interoperability issue of the components and metadata among the middleware. This paper introduces the Simple Object Application Framework (SOAF) which supports heterogeneous resources and platform-independent component-based development, with the abstract programming style of the object-oriented frameworks and the XML-SOAP based component persistence mechanism.

An electronic services which are based on Internet/Intranet business transactions are available to e-market places and get the broader business concepts. Component-based e-commerce technology is a recent trend towards resolving the e-commerce chanange at both system and ap-plication levels. The basic capabilities of component based systems should include the plug and play features at various granularities, interoper-ability across networks and mobility in various networking environments. E-business application developers are attempting to more towards web-service as a mechanism for developing component-based web-applications. Traditional process and development models are inadequately architectured to meet the rapidly evolving needs for the future of scalable web services. In this thesis, we focus specifically on the issues of e-business system architecture based on web service for establishing e-business system. We specifies and identifies design pattern for applying e-business domain in the context of multiple entities. We investigate prototype and frameworks to develope components for e-business application based suggested process. We present a worked example to demonstrate the behavior of Customer Authentication System(CAS) development with component and recommend process. Final]Y, we indicate and view on future directions in component-based development in the context of electronic business.

소프트웨어의 재사용을 위한 방법 중에 최근 빠르게 확산되고 있는 방식으로 컴포넌트 기반의 소프트웨어 개발(CBD : Component-Based Development)방식이 있다. CBD에 있어 컴포넌트 시스템은 잘 정의된 아키텍처를 기반으로 개발되어야 한다. 컴포넌트 시스템의 아키텍처를 정확하고 엄밀하게 설계, 분석하기 위해서는 아키텍처 기술 언어(ADL)의 사용이 필요하다. 아키텍처 모델링에 ADL을 효과적으로 사용하기 위해서는 ADL로 기술된 아키텍처 모델을 효율적으로 분석, 처리, 관리할 수 있는 지원 환경이 필수적이다. 본 논문에서는 ADL 모델 지원 환경 시스템의 구조를 기술하고 본 연구팀에서 개발 중인 ADL 모델 관리기의 구조를 기술한다. 또한 ADL 모델 관리기 개발에 기본이 되는 XML 기반 ADL 메타모델을 정의한다.

오늘날의 컴퓨팅 시스템은 비즈니스 거래와 분산 업무 처리로 확대되어가고 있으며 정보 기술은 점차적으로 재사용성과 독립성 그리고 이식성을 가진 컴포넌트를 기반으로 한 응용 개발이 확산되고 있다. 컴포넌트 개발 형태는 코드의 재사용이나 클래스 라이브러리보다 좀 더 발전된 형태의 부품개발 형태로서, CBD(Component Based Development)를 기초로 한다. 그러나 CBD를 이용하여 새로운 컴포넌트를 구축하는 비용의 증가와 함께 비즈니스 요구사항에 맞는 컴포넌트 개발을 위한 노력이 필요하며, 빠르고 정확한 컴포넌트 정보를 지원할 수 있도록 시스템 측면에서 정규화 형태의 컴포넌트 모델이 요구되고 있다. 본 논문에서는 사용자 요구사항에 접근하고, 재사용성과 독립성, 그리고 이식성을 가진 컴포넌트를 추출하고, 컴포넌트를 대상으로 인터페이스 나타내고자 한다. 따라서 본 논문에서는 학부생들을 위한 학생정보시스템 구축을 위한 시스템 분석 및 설계 모델을 RUP(Rational Unified Processing) 방법론을 이용한다.

복잡한 응용 프로그램을 빠르게 개발하고 이의 유지보수가 용이하도록 하기 위해 재사용 가능한 컴포넌트 기반의 소프트웨언 개발(CBD: Component-Based Development)개념이 확산되고 있고, 이와 관련 되어 컴포넌트 재사용성을 높이기 위한 EJB, COM, CCM 등과 같은 컴포넌트 모델과 이의 개발 및 이미 개발된 컴포넌트를 재사용하고자 하는 연구가 다양하게 진행되고 있다. 컴포넌트를 기반으로 시스템을 효과적으로 구성하기 위해서는 컴포넌트들이 서로 정확하게 결합하여 작동할 수 있는 아키텍쳐를 기반으로 컴포넌트의 조림 작업이 이루어져야 한다. 잘 정의된 아키텍쳐가 존재하면, 시스템이 상위수준에서 어떻게 구성되어 있고, 어떠한 기능을 수행하는지의 방향을 제시해 주므로 조립하는 시스템이 제공하는 서비스를 추상화하여 표현할 수 있다. 본 논문은 제 삼자에 의해 개발된 컴포넌트들의 조림을 통한 시스템 개발을 지원하기 위하여 아키텍쳐 기반의 시스템 설계 방법을 제안하고 이를 지원하는 도구인 COBALT(Component-Based Application DeveLopment Tool) 조립도구의 아키텍쳐 모델러를 소개한다.

Component-based development is being generalized as the spread of software reuse technology for rapid development productivity and high quality software.In the CBD, the identification of independent and reusable component is the one of important tasks for component-based system development. Because existing methodologies providing component identification techniques provide techniques based on heuristic techniques of component developer, it is difficult for general developers to identify components using these methods. Therefore, this paper suggests new identification factors and a technique by considering dependency characteristics according to method call types and method call directions and dependency degree. Furthermore, proposed technique is verified through case study; business components based on system components are identified effectively.

Connector's role between components is very important in the CBD(Component Based Development). The most connector has process ADL based rrethod was choosing FIFO method by component request. But in case many component's with various characteristics request It is difficult that this method operate efficiently, In this research, I did design and implement priority connector considering component's processing time, Also, I used Wright architecture for formal specification. Application result of proposed connector was spend more 388ms compares with existent FIFO method in total processing time. But this method could handle preferentially from components that have short processing time. Also, in case of component's waiting time in connector, existent FIFO method is 23323,1 ms and proposal method is 12731.27ms, So, proposal method could reduce waiting time for component process.

Framework has constructive and extendable code. It is consist of the variable design collections. In the aspect of the classes's collection, it is similar to the class library. but it is different to provide the architecture which is possible to develop the application rather than the collection of the simple classes. In framework it is very important factor to develop and control the component library. In this paper, we design the usable component model through defining the meta-relation between components and proposed the sample case using this model.
