Software development process evolves by component based development(CBD) process and introduction to configuration management system is risen recently. In this paper, we explained component configuration management system evolved out of CBD methodology and focused on the specification management in component configuration management. The component specification is being based on XML that is a normalization document. Also, component version management and dependency management are achieved by a component name. And component dependency information is just the integration information using a component specification name used in the composition when component specification is composed. Thus we confirmed possibility of version management and dependency management using the specification.

CBD(Component Based Development) can make use of component of block unit that is implementation beforehand and shorten software development cost and time. Also, component can reduce complexity for the large application development because it can hide detail part of internal and offer interface. Common requirement of family in the enterprise framework environment can express workflow, but it is very difficult that express special workflow in single component on various family member's requirement. Therefore, necessity about workflow variability management between component for family member and implementation method had been required constantly This treatise presents implementation techniques for component workflow variability in enterprise framework under .NET base. Presented component workflow variability implementation techniques supposes that commonness business workflow that family can use in enterprise workflow was created already in component, and improve workflow's extensity between component by workflow composition between special component and techniques for practice to various family member.

Now we are following component-based software development as a solution to improve the reusability, reliability, and extensibility of the software. To support these, the developed components must be reused through component repository at software development. However, traditional centralized repositories couldn't activate component markets since not only the number of users were restricted but also most of the provided components were those on clients like user interface and so on. Recently, a lot of server-side components, reused in a specific domain, have appeared thanks to the development of both Internet technology and component technology such as EJB, DCOM, etc. Therefore, component repositories, based on domain information, classify and provide components and must offer web-based service for many users to use it stably. This study introduces the implementation of a component repository based on J2EE application model. It provides application developers with the service to search and extract appropriate components, and supplies them reliable services in web environment.

Because of rapid development of software technology, a number of software professionals have been concerned with component-based development methodologies. Up to date, the evaluation of component quality has been focused on object-oriented metric based methodology. But this paper presents the selection process and evaluation criteria based on an MCDM(Multiple Criteria Decision Making) technique for the selection of optimal COTS component from consumers' viewpoints. We considered functionality, efficiency and usability based on ISO/IEC 9126 for quality measurement and conducted practical analysis into commercial EJB component in internet. This paper shows that the proposed selection technique is applicable for the selection of the optimal COTS component.

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.

Recently in the field of defense Modeling and Simulation (M&S), Component-Based Development technology is widely applying to save the cost and increase the reusability of weapon system development. Related with this, researches for rapid reconfiguration and simulation of the component-standardized weapon system is actively carrying out. To rapidly reconfigure the new weapon system, complex and various functions of component information has to be effectively searched. So, it requires differentiated search technique unlike existing Keyword-based Search method. Semantic Search System provides semantically related information among the extensive information. In this research, metadata of weapon system components and their representative functional words are built as an ontology. And it provides an ontology-based semantic search system.

Today\\`s wide variety of component-based development environments supports the component framework that can be used only for the specific type of components. And many researches have shown that it is necessary for the component-based development environment to support recursive component composition, various kinds of component composition patterns and the multi-tier component architecture for the real benefits of software component composition. In this paper we propose the component composition specification which can not only specify the interaction contracts between components but also supports recursive component composition, and we also propose the component composition model based on this component composition specification. The proposed component composition specification can express the contractual properties that existing component specification techniques cannot specify, and it can be also used to implement the component architectures with multi-tier concept and the tool for component composition through supporting the various kinds of component composition patterns.

In this paper, we demonstrate the implementation case using component based development tool under development process for application developments. The tool suggested provides the programming environment for the development of distributed manufacturing applications primarily. The development tool is classified into visual component, logic component, data component, knowledge component, neural net component, and service component which is a core component for the support component edit and execution. We applied the tool to the domain of the design and routing plan to retrieve existing similar design models in database, initiate a model, generate a process plan, and store the new model in the database automatically. Utilizing the tool, it integrates a geometric modeler, engineering/manufacturing database, and knowledge sources over the Internet.

As an optimun alternatives for the solution of recent software crisis, we have to develop component technologies so as to develop and propagate business components for various domains to industries. For the sake of development of business components, a conceptual architecture which defines a model for component assembly should be prescribed first, and a systematic specification method based on this model be defined, so we can build a system environments for making specifications and development of each component by the consistent scheme. In this study, we propose a domain architecture model for implementing the pUblic component bank as a project supported by the ministry of information and communication, discuss the conceptual model of specification for developing components of storing component bank, specification steps, specification approach for application of business domains and the development results of them.

According to change of software development technique as design pattern, component based development etc.., web server development part is applied activity to fit in various user requirement. Especially, EJB as sewer side component model much researches and introduce by easy and various development support. Also, component composing techniques is receiving many interests by easy and efficient application way that architecture based C2 style architecture with message handling. But, in case of EJB component that can not cail thread, C2 framework modification is unavoidable for component composition by C2 style architeccture. For this, we propose techniques to use Adapter pattern to be one of structure pattern among pattern. That is, did so that component composition by C2 style architecture may can consist changing to be able to call thread function in EJB by Adapter pattern.
