An OLAP system is a decision support tool with which a user can analyze the information interactively in the various aspects. Applying CBD(Component-based Development), which treats software as components, to implement an OLAP system has limitation in the flexibility and reusability. To overcome those limitations, we propose a method of CBD(template-based CBD) which integrates the concept of template and CBD. Through the implementation of an OLAP system with the proposed TCBD, we show that our proposal is more efficient in flexibility and reusability than CBD and decreases the period of time for the development, test, and debug.

In this study, a comparative analysis have been conducted to examine seismic reinforcement effect of a school building that is designed with a CBD (Channel Beam Damper) system supported by H-frame with existing non-seismic RC frame. As a result of experiment, seismic reinforcement specimen with CBD system showed hysteretic characteristics of a large ellipse with great energy dissipation ability and increased strength and stiffness, while non-seismic design specimen showed rapid reduction in strength and brittle shear failure at top and bottom of the left and right column. In addition, comparing the stiffness reduction between the two specimens, CBD system was effective in preventing the reduction of stiffness. Energy dissipation ability of specimen reinforced by CBD system was about 4.0 times higher than the non-reinforced specimen. Such enhancement in energy dissipation ability could be considered as the result of improved strength and deformation for further application in designing of seismic reinforcement.

Among many recent methods developing software, the method of component-based development (CBD), which refers to the method of treat-ing software as parts of a larger whole, and developing new applications through the assembly and synthesis of existing software, has been thoroughly studied. CBD, however, has demerits that cause difficulty in making inferences and understanding the code of components. and lack adequate documentation because the method of CBD divides systems according to the functional characteristics of these systems. Therefore, this study shows how to reuse components without difficulty and reduce the development time of systems and development costs by compensat-ing for the weak points of the method of CBD. Aspect-Oriented programming technique has been applied to the method of CBD and the UML diagram for this purpose.

세계적인 SW 산업의 변화 추이로 볼 때, 우리나라 SW업체들도 SW개발 체제를 하루바삐 CBD로 전환해야겠다는 데 대해서는 의심의 여지가 없다. 기업의 CBD 능력은 지속적인 사업구조 조정 및 신규사업 창출이 불가피한 21세기의 경영환경에서 필수적으로 확보해야 할 기업 핵심 역량으로 간주되고 있다. 선진국에서는 CBD가 90년대 중반부터 본격화되어 이제는 기업 정보시스템 구축 방식의 주류가 되어있다. 국내에서도 금융, 국방 부분을 선도로 CBD에 의한 정보시스템 구축을 요구하기 시작했으며, 향후 그 수요가 급증할 전망이다. 그러나 문제는 CBD로의 전환에는 여러 가지 역경이 도사리고 있다는데 있다. 특히, 본 논문에서는 재사용성에 의해 기대되는 효과에 비해 실질적인 재사용의 결과도출을 이루지 못하는 문제점 개선을 위한 Opportunity Tree를 제안해본다. 또한, CBD로 전환함으로써 거둘 수 있는 이득이 무엇인지, 전환을 위해 갖추어야 할 조건이 무엇인지를 확인하고자 한다.

Defence Information System has surely required the guarantee of interoperability between systems as performing task oriented functions. To improve interoperability between them and use the benefits of component based development, defense officers are planning to develop COE like a kind of component bank concept. Defense component development methodology(ADDMe) within COE is a new approach of component based methodology for Defense environment after comparing, analyzing, and synthesizing with traditional CBDs. In this paper we introduce advanced defense component development methodology(ADDMe) and present checklist for improving interoperability between Defence component based systems which are developed with ADDMe. With our proposed interoperability's checklist, we can improve interoperability of defense component based systems through applying per each phase of ADDMe.

CBD(Component Based development)가 이미 완성된 소프트웨어 모듈인 컴포넌트들을 특정 목적을 위해 배치하고 조립함으로써 품질 보증된 고생산성의 재사용을 가능하게 됨에 따라, 최근 IT 비즈니스 솔루션 도출을 위한 핵심 적인 기술 전략으로 인식되고 있다. 따라서 영 역에 적절한 컴포넌트의 추출과 개발 및 응용 시스템으로의 전개를 위한 컴포넌트들의 배치와 조립 등을 포함하는 일련의 CBD 프로세스를 실제화 하기 위해서는 아키텍쳐 기반의 접근과 제어가 매우 중요하다. 하지만 대부분의 CBD 연구는 비즈니스 로직들의 기능성을 그룹화한 컴포넌트의 생산에 초점을 두고 있지 컴포넌트간의 상호작용을 명시하는 아키텍쳐 정보의 관리를 간과함으로써 컴포넌트의 조립과 통합을 통한 CBD 시스템으로의 전개는 극히 어려운 실정이다. 따라서, 본 논문에서는 CHD 프로세스 상에서 아키텍쳐 접근의 중요성과 전개 방법을 살펴보고, 컴포넌트 프레임워크(Component Framework)를 위한 아키텍쳐의 계층을 새롭게 재정의 하며 그 의미를 설명한다. 이를 위해 영역 분석 및 설계 정보를 선언적으로 명시하는 수단이며, 도메인 내에서 특정 서비스를 제공하는 컴포넌트간의 일반적 결합 방식의 규정하기 위한 수단으로서 설계 패턴을 이용하여 서비스 아키텍쳐 패턴을 정의하고 실 예로 적용한다.

A decrease in the fertility rate leads to a reduction of troops, so the need to efficiently operate the troops is growing. Therefore, it is necessary to develop a system for estimating warship manpower. In this study, system development was performed according to the CBD methodology. The user requirements were defined and the system function that satisfies the requirements was derived. And through the development process, the CBD methodology and the systems engineering process were compared. As a result, similarities were confirmed in the analysis and concept design stages, so the possibility of merging the two processes was suggested.

Since Component-Based Development, or CBD, struck Korea SI industry a heavy blow several years ago, many major SI companies in Korea have implemented the CBD practices in real world, leveraging supports from the government and academic world. The result, however, falls short of their expectations. The major reason is that they have mainly focused on CBD processes and technical issues around it, although it is necessary as well to deal with other non-technical issues in order to make business values from CBD. This paper begins with reminding us what CBD tries to achieve indeed in terms of software development processes, then recognizes what we have achieved so far introducing a recent CBD project case, BOK-WIRE system. Thereafter, it reveals the chances that SI companies must take in order to make their CBD efforts succeed, pointing out what are the roadblocks really.

As for the software development, it is complicated, and size of software is growing larger. And contraction of a software development period is required acutely because it is short a period of software life cycle. Also, it becomes harder development and a maintenance because it is short a life cycle of developed software. According to this an effort is increased in order to reduce a development cost and time as using a component to have been implemented previously in development of software. A current component technology is developing into a very fast speed and is bringing a large change into development of a Web base system in addition to existing software development method. In this paper, we were handling a related technology for Web system development of a CBD base systematically and derived an issue to apply it to development of a Web system and presented an efficient practical use method of a component technology. First of all we looked into a component technology and a CBD methodology systematically and described a component technology in Web. Also, we proposed a method to increase development and efficiency of practical use of a Web system based on a component. The this study result can decrease a development cost of a Web system and a load of maintenance management through the re-use of a code.
