기존 정보체계는 사용자 요구와 새로운 기술의 도입으로 급속하게 발전하고 있으며, 정보시스템의 재사용성과 확장성, 유지 보수를 위하여 EJB, COM+, CCM 모델 같은 컴포넌트 기술과 컴포넌트 기반 개발 방법론인 CBD 방법론이 연구되고 있다. 또한 이러한 컴포넌트 기술을 이용한 기존 정보시스템의 변환 연구도 같이 이루어지고 있으며, 대표적인 연구로는 미 국방성의 FACELIFT 프로젝트와 카네기멜론 대학 프로젝트 등이 있다. 반면에 현재의 국내 군 정보시스템은 다양한 플랫폼 및 언어 그리고 업무 지향적인 개발로 인해 자원이 낭비되고, 유지보수가 어려운 문제점이 있다. 따라서 본 논문에서는 이미 개발되어 운용중인 군 정보시스템을 분석하여 컴포넌트 기술에 의한 웹 환경으로 변환하는 절차를 제시하고, 클라이언트/서버 구조로 운용중인 군인연금서비스시스템의 일부분을 컴포넌트 기술을 이용하여 웹 환경으로 변환하였다.

Recently, development paradigm of information system is turning into object oriented and component based, and this methodology is leading the software industry. To acclimatize aptly to this trend, users demand the assessment of software expenses to change with the appropriate model of computing costs of the environment, and some people are actually studying the concept of Object Oriented Function Point and UCP method. Especially, Object Oriented Function Point Measurement Process has good points in overcoming the bound of LOC and the existing the Function Point Measurement Process because Object Oriented Function Point Measurement Process is applicable to the early stage of development project mainly with the used cases, and valid to the life long period as the each stage of software products develops, and always understandable to communicate with users by the UML mark rules. Accordingly, this research is to measure Functional Point at ROFP and AOFP in accordance with the development project of information system by the national defense CBD methodology procedures and UML Interrelation Analysis that are recently and widely used in the developmental environment of object oriented information system. Furthermore, this study suggests the measurement method to obtain Functional Point, and identifies service function and object/class function in the correlation analysis of use case and class based on the products and UML modeling via traditional FPA model and object oriented FPA model. Above all, this study is to demonstrate the improvement of traditional Function Point Measurement Process, IFPUG-CPM and software cost basis, and reveal Function Point Measurement Process, which is appropriate to the development of object oriented information system, and suggest the evaluation results of the compatibility through case studies.

In this paper we describe interoperability maturity measurement, due to highlight a momentous issue on interoperability between heterogeneous distributed component based systems. it also suggests one of various ways for supporting interoperability between each other different component based systems, that is, using web services based mechanism and also revises 'LISI (Level of information systems interoperability)' model to measure interoperability maturity. We also develop the interoperability questionnaire based on the interoperability factors considered at each phase of component based development process, which is possible to measure interoperability maturity between heterogeneous distributed component systems. Based on revised interoperability maturity model and questionnaire we measure each interoperability maturity on examples of two different implementations, that is, web services and distributed object based mechanism. As a result, we suggest an enhanced interoperability way based on analysing problems af these measured results.
