Component-based software development (CBSD) is a method for building large software system by integrating previously-existing software components. Software development method using components has several advantages such that reducing time to delivery and development costs, and increasing productivity etc. But integrating components developed from multiple vendors is too difficult As a result it is required the understanding on the context of use to develop reusable components. The context of use for software component of determined by software architecture. Therefore, it is possible to develop an application based on components if is based on software architecture. Also, it is essential to consider domain concepts for CBSD. To increase the reusability of components. we should develop components in a domain which is a set of related systems. In this paper, we proposed a domain architecture development methodology that supports component-based software development. Domain architecture that represents components and their relationship is produced through domain analysis and design process. We believe that component development methodology using proposed domain architecture can efficiently develop highly reusable components as well as easily develop and application using information acquired from domain architecture.

Component-based Software development(CBSD) is widely used in various area due to its efficiency of time, cost and effort. In the embedded software which has high dependency of platform and can be developed by product family, the efficiency of CBSD is maximized by reuse. These embedded software has various limitations of the resources. Specially, the effective energy consumption is very important in the portable embedded software such as smart phone and tablet PC, because they are operated with limited energy source like a battery. Therefore, energy efficient problem became very important issue in the CBSD. In this paper, we identified characteristics and environment that influence energy consumption of components. Afterward, we defined a component specification language which is consisted to describe energy characteristics of the components. This supposed specification language can be utilized to energy efficient component search and selection.

The Component-Based Software Development (CBSD) has established itself as a sound paradigm in the software engineering discipline and has gained wide spread acceptance in the industry. The CBSD relies on the availability of standard software components for encapsulation of specific functionality. This paper presents the framework for the development of a software component for the design of general member cross-sections. The proposed component can be used in component-based structural engineering software or as a stand-alone program developed around the component. This paper describes the use-case scenarios for the component, its design patterns, object models, class hierarchy, the integrated and unified handling of cross-section behavior and implementation issue. It is expected that a component developed using the proposed patterns and model can be used in analysis, design and detailing packages to handle reinforced concrete, partially prestressed concrete, steel-concrete composite and steel sections. The component can provide the entire response parameters of the cross section including determination of geometric properties, elastic stresses, flexural capacity, moment-curvature, and ductility ratios. The component can also be used as the main computational engine for stand-alone section design software. The component can be further extended to handle the retrofitting and strengthening of cross-sections, shear and torsional response, determination of fire-damage parameters, etc.

Web-Based Education System changed from one side transmission of information to bi-directional information exchange with user. Accordingly, It had been implemented on 3-tier models with each function separation using database and server side language such as CGI (Common Gateway Interface). But, The CBSD(Component Based Software Development) techniques receives many interests recently, and efforts to apply this are appearing. Thus, In this research implemented component base question solving system. For this, I used EJB(Enterprise Java Beans) that is web server component model, and used Petri-Net for typical specification about message flow between components.

Component users must customize components they obtain from providers, in order to fit them to their own purposes. Normally, a component consists of black-box parts and white-box parts. Component users customize a component by modifying white-box parts of a component, and the customization faults appear through the interaction between black-box parts and white-box parts. Customization testing could be an integration testing of these two parts of a component. Also, customization testing in CBSD should select effective test data to reduce the testing cost, since CBSD aims to reduce the development cost. Therefore, this paper proposes a customization testing technique based on COM architecture through analyzing many COM components, and the technique selects effective test data. This paper evaluates the effectiveness of the test data selected by the proposed technique through an empirical study. It applies the techlique to a large-scale component-based system, Chamois, and it shows that the technique enables us to test customized COM components that run in a real component-based system

Recently, component-based software development is getting accepted in industry as a new effective software development paradigm. Since the introduction of component-based software engineering (CBSE) in later 90's, the CBSD research has focused largely on component modeling, methodology, architecture and component platform. However, as the number of components available on the market increases, it becomes more important to devise metrics to quantify the various characteristics of components. In this Paper, we propose metrics for measuring the complexity, customizability, and reusability of software components. Complexity metric can be used to evaluate the complexity of components. Customizability is used to measure how efficiently and widely the components can be customized for organization specific requirement. Reusability can be used to measure the degree of features that are reused in building applications. We expect that these metrics can be effectively used to quantify the characteristics of components.

The purpose of CBSD(Component Based Software Development) if to develop software using a reuse component and components assembly. The reused components have to be adapter for satisfaction of requirement specification. This paper represents a component adaption method which reuse previously developed component or legacy system, using an adaptation component called by TA(Transaction Adaptor). The adaptation using TA transmits XML data that is translated into stream type, from a client to on host system. And we introduce RS(Rule Server) which gets some Information from XML data for application program development. Through the Interaction of TA and RS, we can improve effectiveness of component development and maintenance and we can reuse legacy system.
