Today's computing system has expanded its application to business trade and distributed work transactions using the Internet. As the demand for more flexible, adaptable, extensible, and robust web-based enterprise, these application development has been gradually expanded based on reusable, independent, and portable components. Component Based Development (CBD) works by developing and evolving software from selected reusable software components and then assembling them within appropriate software architecture. However, it requires an increase in cost to build new components as well as the necessary effort to develop of the business requirement these components. Standardized component models are required as well from the perspective of systems in order to support rapid and exact component information transmission on the web. In this paper, we describe the e-Business Component Development with agent for rapid application development on the web that correspond to the demands of users in the business domain. We design and implement the specifications of e-business components by combining these demands. In order to improve the agent register and retrieval, we propose the intelligent search and register agents, which can conduct more precise searching and specializing for components. The system enables the locating of user's frequently used components through an agent involving register and retrieval, as well as rapid procedures for registers The e-BCOS (e-Business Component System) is the agent system for the user to register distributed components and to search for components Information. The e-BCOS increases reusability through the e-business component development of distributed components in the business domain. For the share and delivery, specification with XML is acceptable to user's variable order e-BCOS Includes the effective investment, timeliness, reliability, efficiency, and maintenance effort by with agent.

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.

정보화 시대로의 전환에 대한 요구를 충실하게 지원하고 점차적으로 인터넷을 이용한 비즈니스 거래와 분산 업무 처리 요구에 따른 e-commerce 환경으로부터 intranet과 extranet, 즉 고객 공급자 동업자 기업, 기관, 고용인등의 비즈니스에서 필요한 관계가 포함되어 통합되어진 e-busienss로의 어플리케이션이 요구되고 있다. 따라서 본 논문에서는 e-business 환경에서 사용자가 원하는 웹 애플리케이션이 정확하고 빠르게 구축될 수 있도록 e-business 컴포넌트 프로세스를 제안하며, 기존의 컴포넌트를 재사용 가능하도록 비즈니스 측면에서 컴포넌트 카테고리를 정하여 분류하고 통합을 통해 솔루션을 구축할 수 있도록 한다. 이는 e-business 컴포넌트 프로세스를 통해 이는 결국 분석된 모든 e-business 컴포넌트를 등록하고 검색 및 다운로드 할 수 있는 통합 시스템으로 제시되어진다. 기존의 컴포넌트는 분류를 통해 비지니스 측면의 컴포넌트로 재사용 가능하도륵 하며 현재의 B2B(Business to Business)를 원활히 하는데 목적을 둔다.

The computing systems of today expanded business trade and distributed business process Internet. More and more systems are developed from components with exactly reusability, independency, and portability. Component based development is focused on advanced concepts rater than passive manipulation or source code in class library. The primary component construction in CBD. However, lead to an additional cost for reconstructing the new component with CBD model. It also difficult to serve component information with rapidly and exactly, which normalization model are not established, frequency user logging in Web caused overload. A lot of difficult issues and aspects of Component Based Development have to be investigated to develop good component-based products. There is no established normalization model which will guarantee a proper treatment of components. This paper elaborates on some of those aspects of web application to adapt user requirement with exactly and rapidly. Distributed components in this paper are used in the most tiny size on network and suggest the network-addressable interface based on business domain. We also discuss the internal and external specifications for grasping component internal and external relations of user requirements to be analyzed. The specifications are stored on Servlets after dividing the information between session and entity as an EJB (Enterprise JavaBeans) that are reusable unit size in business domain. The reusable units are used in business component through query to get business component. As a major contribution, we propose a systems model for registration, auto-arrange, search, test, and download component, which covers component reusability and component customization.

Due to not only proven stability and reliability but a significant investment and years of accumulated -experience and knowledge, legacy systems have supported the core business applications of a number of organizations over many years. While the emergence of Web-based e-business environments requires externalizing core business processes to the Web. This is a competitive advantage in the new economy. Consequently, organizations now need to mine the business value buried in the legacy systems for reuse in new e-business applications. In this paper we suggest a systematic approach to mining components that perform specific business services and that consist of the legacy system's assets to be leveraged on the modem platform. The proposed activities are divided into several tasks. First, use cases that realize the business processes are captured. Secondly, a design model is constructed for each identified use case in order to integrate the use cases with the similar functionalities. Thirdly, we identify component candidates from the design model and then adjust the component candidates by considering common elements among the candidate components. And also business components are divided into three more fine-grained components to deploy them onto J2EE/EJB environments. finally, we define the interfaces of components which provide functionalities of the components as operations.

ebXML(Electronic Business XML) is a global eBusiness framework standard which provides solutions to interoperability problem between heterogeneous eBusiness systems. ebXML framework includes Business Process Specification, Core Components, Registry/Repository and Messaging Service as its major components. Based on this framework, ebXML business transactions are executed by exchanging appropriate business documents as specified in Business Process Specification. And required business documents are generated by assembling Core Components at the Business Process design time. In this paper, we present technical architecture of ebXML framework and Core Component technology, and then explain design and implementation issues of ebXML business document generation tool.

The current software development type is based on CBD (Component Based Development). However, it requires a new component model that can support rapid and accurate component information on the web due to the cost increase of building new components using CBD. The purposed of this paper is to promptly develop an application on the web which fulfills users' demand and to provide specific interface regarding the small scales of distributed component in business domains. The e-BCOS(e-Business Component System) is the agent system for the users to register distributed components and to search component information, which would increase reusability through the e-business component development of distributed components in business domains and help the users understand the information about the component. Moreover, XML is employed for specification which allows smooth specification sharing and delivery to satisfy users' variable demands.
