Developers can reuse not only class code but also wide range of knowledge on domain by reusing framework. Existing Object-Oriented Methodology and Catalysis Methodology were presented when redefining component in the course of redesigning framework. However, existing methodologies have weakness that entire process is waterfall mode or design of interface lays too much stress on implementation stage. So, this thesis will present Component-Oriented Methodology for the reuse of framework, and construct the environment for framework and domain development. That is, domain is analyzed by input of domain knowledge on real world to create software based on component, and hotspot is identified through analyzed information, and refactoring by putting additional information on users and developers. After that, I will create domain framework and application framework depending on domain. In this Component-Oriented Methodology, information is searched, understood and extracted or composite through component library storage internally. Then this information is classified into the information on component, and used as additional information in redesigning. With this, developer can obtain reusability, easiness and portability by constructing infrastructure environment that allows to register, update and delete component through Component Management System(CMS) under he development environment which can be easily applied to his own application using framework component, in this thesis, CoRBA(Common Object Request Broker Architecture) environment.

GIS provides the various analyzing and displaying using diverse spatial data have supported the powerful functionality and friendly user-interface. But, early GIS software is developed as package tool, it have many difficulties with reducing the cost of developing GPS application and satisfying the various user requirements. At present, the developed GPS applications across multiple domains, despite the common features are built separately for each domain in terms of software engineering development followed out waste of time and money expenditure. However, common features between GPS applications, if deployed as a component assembly and reuse components in terms of enabling the two kinds of component-based development can bring out the beneficial results. In this paper, we described the Analysis and design of GPS ApplicationsS based on Component. Each GPS component is composed of many objects accomplish the atomic service processing and cooperate with each other. And, GPS components meets the qualifications of thc low cost of developing GPS application because of the reusability and re-composition.

In these days, because of internet activation, each organs of education or istructors develop and manage the web based education system, but component development that used in web based education system development is not ready. When we develop the web education system using component, we can gain the various desired result of reusability, interaction in various computers, expansion, reduction of development time, saving of development expense, etc. Therefore, in this paper we classified the web based education components by the function of web based education system, did modeling for development process of components, and chose the component platform that can reuse components in distributed computing environment that the client/server environment is supported. The induction of these web based education components will be give many assistance to development of the web based education system.

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.

In this paper, we propose a steering concept that considers overall aspects in the CBSD (Component-Based Software Development) environments. While many researches which are concentrated on using components, market promotion and component development itself seem to be insufficient. To overcome this problem, we introduce a brokerage concept called“Value-Added Brokerage Concept”that provides the following three services：1) domain architecture-based component promotion, 2) intelligent component search, and 3) white-box service. Domain architecture-based component promotion facilitates balancing component production and promoting architecture-level large scale reuse. Intelligent component search enables to overcome the long time search and selection problem. Finally, white-box service is for solving maintenance problems, which is one of the most critical problem in the CBSD environments. Especially, we expect this proposed concept would be well adapted to our national environments.

The component-based development methodology becomes famous as the reuse technology for independence and productivity of software development It is necessary component metrics for component-based systems, because It should be measurable to improve the quality of the software. Hence, in this paper, we propose component cohesion and coupling metrics which is reflected in characteristics of component. The operation use value is calculated by the information of classes interface commonly uses to offer the component's service. And, the operation similarity value is calculated by the operations use value. Component cohesion and coupling is calculated by the operation similarity and based of the information which is extracted in the analysis phase. And, we examine the necessity of component metrics in comparison with object-oriented metrics.

Recently, above 50 percentages of software are being developed based on distributed application platforms. And recent technologies such as EJB(Enterprise Java Beans)[1]COM(Component Object Model)[2] CORBA(Common Object Request Broker Architecture)[3] have been advanced for distributed component-based software development . Therefore a systematic development process is necessary to develop component based applications using distributed application platforms. However, most of component-base software development processes do not define concrete flows between tasks and relationships among artifacts of each task Also, distribution issues are not considered explicitly in most of component-based software development In this paper, we present an approach to analyze and design software based on distributed components. In this approach, we propose systematic guidelines for developing a software based on Unified process and the relationships among artifacts which are produced, Also we explicitly consider the distribution issues such as performance, fault tolerance, security, distributed transaction of CORBA environments.

According to the development of information & web technology and the amount of information increases, there have been numerous problems exposed. Although, software engineers try to overcome the limitations by using software agent and web service, there hasn't been satisfactory result in the paradigm of current software agent being a provider to the user's demand. Moreover, the latest configuration of software development is based on CBD (Component Based Development). However, to construct new component using CBD costs great deal of expenses and therefore, a new model which can acquirecomponent information on the web promptly and accurately with low expenses is required. In this paper, the repository management system which acquires and manages on the Semantic web is designed and compare them to the existing component repository management and present its analysis result. In addition, to overcome the limitations of existing component repository system; low accuracy of search result, restrictive search vocabulary and faulty information, the specific plan is presented to perform a knowledge search for the component.

Recently, many IT organizations develop software system with reusable component. Effective reusing of components increases software development productivity and quality. And, development of high quality component documents decrease maintenance problems, which are issues in component-based software development. In this paper, we propose a quality evaluation model of component development documents by empirical research. It consists of component quality reference model (CQRM) and quality evaluation model (CQEM). CQRM contains quality guidelines for component developers. CQEM contains evaluation guidelines for component consumers and distributors. We performed case study to verify this paper. Also, we presented quality improvement methods and improvement effects of component development documents. The quality evaluation model of component development documents proposed in this paper leads component development documents with high quality, and provides a rational quality evaluation model.
