This paper first examines the notion of software and the importance of software development and then presents twelve fundamental principles for software architecture design as the key enabling technology for effective software development. This paper divides design steps into four groups, i.e. analyzing the problem, deciding architecture modeling methods, architecture design process and architecture evaluation. Then it identifies the principles within and across the various steps of software architecture design and explains their roles.

MND(Ministry of National Defense) has developed .nm AF(Ministry of National Defense Architecture Framework) to guarantee interoperability among defense information systems. Users can easily and consistently develop architecture products through MND AF. There is necessity for development if CADM(Core Architecture Data Model), which facilitate exchange, integration, and comparison for architecture data, to store architecture data from architecture products and reuse them. We developed CADM from defining entities and relationships that satisfy data requirement of each architecture product from MND AF. After we developed architecture products about MIMS(Military Intelligence Management System), and inserted these architecture data to CADM repository. we verified CADM entities and relationships through query. Through CABM which provides common data model for the whole my architectures, interoperability and integration among defense information systems ran be improved, and integrated defense information resources efficiently can be managed.

Improving the competitiveness of software products in the market involves procuring the means to design software architecture that deliver qualities necessitated by stakeholder requirements within allocated budget, thereby improving the cost-effectiveness of the end product. Currently, software architecture evaluation methods are used to predict and review qualities inherent in software architecture designs and to choose a candidate architecture that delivers desired qualities. Existing software architecture evaluation methods, however, fail to address the cost considerations dependent on the architecture chosen for product implementation. In this paper we suggest a cost estimation method for software architecture which adapts the cost drivers in the software cost estimation model COCOMO II to support cost estimation during architecture evaluation. The suggested method can be performed in coordination with existing software architecture evaluation efforts and supplements existing architecture evaluation techniques with guidelines for identifying and evaluating cost drivers in candidate software architectures without incurring extra overhead. The accuracy of the cost estimation using the suggested method is verified through application of the method to the architecture candidates used in RPS (Robot Patrol System), a surveillance embedded system.

소프트웨어 아키텍처의 개념은 2000년경부터 ITA(정보 기술 아키텍처) 또는 소프트웨어 아키텍처라는 이름으로 소프트웨어 아키텍처 산업계, 학계에서 활발한 연구와 실제 프로젝트에 적용이 본격화 되고 있다. 소프트웨어 아키텍처는 시스템 관련자들 간의 이해를 높이는 수단이 되며 개발시스템의 분석, 설계, 개발, 테스트, 유지보수 프로세스의 품질을 좌우하는 주요한 요소로서 전 개발공정을 추적 가능하게 하는 장점을 지니고 있다. 또한 향후 재사용 가능한 시스템의 산출물로서 d용하게 된다. 시스템 전체 구조관점에서의 중요성을 인식하여 RUP방법론을 테일러링 함으로서 J2EE플랫폼의 소프트웨어 아키텍처 프로세스와 핵심요소를 제안한다.

The reuse by using framework is proposed to improve productivity. It is a set of usable and expandable classes and their connectivity. But frameworks are described with programming languages, it is hard for developers to learn the collaborative patterns of a framework by reading it. Patterns are one approach to improving the documentation. But this should be redesigned to expand and redefine the framework. The necessity of the formal description of architecture information is being proposed to relate to programming language. This paper support the following points. First of all, it has been proposed the description of the needed elements when developing a framework using ADL. Secondly, the current development process has been refined to be suitable for developing the domain framework. Thirdly, it has been proposed the development of a application using a framework implemented by an architecture information described with ADL. Overalls, the main contents of this research is defining the ideas of a description and development of an architecture framework using ADL.

MND(Ministry of National Defense) has developed MND AF(Ministry of National Defense Architecture Framework) and CADM(Core Architecture Data Model) to guarantee interoperability among defense information systems. TRM(Technical Reference Model) and SP(Standard Profile) product defined in MND AF is core part of Information Technology Architecture and core element of interoperability guarantee. In this paper, we proposed a method which manages technical service and standard of TRM and SP, and developed TRM and SP management system based on the method. TRM and SP management system provides the basis for interoperability among information systems and a more efficient development and management of TRM and SP product.

Along with shortening the life cycle of software utilization and supporting various types of user functions, the importance of software architecture development has been emphasized recently. If a software architecture is developed flexibly and reliably for expansion to support new functionality, it can quickly cope with new market demands. This paper proposes an architecture design method based on design recovery of open source software to reuse the software in the development of sustainable software system. When using open source software to develop a software system based on software architecture, we can develop a software system rapidly and also can improve the reliability of the system because we use the already proven open source software in the development.

컴포넌트 기반 개발환경이 성숙되면서 아키텍처는 재사용 기반을 제공하는 핵심 기술요소로 인식되고 있으며, 이의 체계적인 설계와 관리를 위한 소프트웨어 아키텍처 설계개념이 중요시되고 있다. 그러나 최근 객체지향 개발 프로세스에서 클래스 단위의 하위수준 모듈에서 시작하여 컴포넌트를 도출해가는 상향식(bottom-up)설계방식이나 컴포넌트 개발에서 강조하는 패턴중심 설계기법은 비즈니스 관점의 전략적 아키텍처 설계가 불가능한 단점이 있다. 이에 본 논문에서는 기존의 아키텍처 설계 기법의 단점을 보완하기 위해 한국전자통신연구원에서 개발한 컴포넌트기반 시스템 개발 방법론인 마르미-III 에서 채택하고 있는 아키덱처 설계기법을 소개하고 이를 적용한 사례를 소개한다.
