웹 문서의 표현 언어로 XML이 대두되면서부터 신속히 애플리케이션을 위한 문서를 제작하는 것이 중요해졌다. 본 논문에서는 UML 쓰임새 중심 방법을 적용하여 XML 문서 편집기를 제작하였다. 쓰임새 방법의 단계는 해당 문제의 범위에서 객체를 찾아내는 도메인 모델링 단계, 시스템의 행동을 식별해내는 쓰임새 모델링 단계, 쓰임새의 정재와 새로운 객체를 찾아내는 계층 모델링 단계, 그리고 실제로 어떻게 구현할 것인가를 설계하는 교류 모델링으로 나누어 DTD 편집기와 XML 편집기를 설계하고 구현하였다.

본 논문에서는 효율적인 전투체계 소프트웨어 개발방안으로 UML(Unified Modeling Language)을 이용한 모델기반개발방법을 제시한다. UML은 소프트웨어 시스템을 모델링하기 위한 언어로 OMG(Object Management Group)에서 관리되고 있는 통합모델링언어이다. 본 논문에서 제시한 UML(Unified Modeling Language)을 이용하여 소프트웨어를 개발 할 경우, 표준화된 모델 언어를 사용하기 때문에 개발자들의 원활한 의사소통이 가능하여 시스템의 심각한 오류를 줄일 수 있다. 또한, 가독성이 높은 객체 모델들을 사용하기 때문에 추후 요구사항에 대한 소프트웨어 유지/보수에 용이하다는 장점을 가진다.

프로덕트 라인 공학에서 프로덕트 라인 아키텍처는 가장 중요한 산출물 중에 하나이다. UML (Unified Modeling Language) 2.x 부터는 아키텍처를 모델링하기 위한 유용한 모델링 요소를 제공하고 있다. 이러한 UML을 이용하여 프로덕트 라인 아키텍처를 모델링하기 위해서는 가변성의 표현이 명시적으로 이루어져야 하지만, UML 자체에는 가변성을 표현하기 위한 방법 및 기법을 명시적으로 기술하고 있지 않다. 본 논문에서는 UML에서 제공하는 확장 메커니즘을 이용하여 가변성을 표현하는 방법을 제안한다. 즉, 모델링요소에 태그값(Tagged Value) 및 스테레오타입을 넣어주어 다양한 관점에서의 가변성을 표기하는 방법을 제안한다.

Systematic modeling methods. which can correctly represent user requirements, are absolutely required to extract components when developing components. But, components are designed and developed In general based on the concept of object modeling so that they lacks in supporting representing cooperation and interaction as well as reuse. It means extracting components is not easy to be applied to complicated and sophisticated large-scale systems. This paper utilizes a role modeling method based on the role of objects, not on objects themselves, to complement object modeling. The Role modeling can break down a complicated system into simple models through abstracting the pattern of objects based on roles of the objects. In this study, an UML-based method extracting components through role modeling is embodied. UML can represent models from various standpoints so that role models arc also viewed from several points of view.

Nowadays the information exchange based on XML such as B2B electronic commerce is spreading. Therefore a systematic and stable management mechanism for storing the exchanged information is needed. For this goal there are many research activities for centering on relational databases the connection between XML application and databases. But when XML data which has hierarchical structure is stored as relational databases which are expressed as relational information, a set of 2-dimensional table, there is a limitation essentially. Accordingly the modeling methodology for storing such structured information in the form of object-relational databases is needed. In order to build good quality application systems, modeling is an important first step. In 1997, the OMG adopted the UML as its standard modeling language. Since industry has warmly embraced UML, its popularity should become more important in the future. So a design methodology based on UML is needed to develop efficient XML applications. In this paper, we propose a unified design methodology for XML applications based on object-relational database using UML. To reach these goals, first we propose a systematic three step methodology to extract UML, second we introduce a XML modeling methodology to design W3C XML schema using UML and third we propose a data modeling methodology for object-relational database schema to store exchanging XML data efficiently.

Hardware and software codesign framework called PeaCE(Ptolemy extension as a Codesign Environment) was developed. It allows to express both data flow and control flow which is described as fFSM which extends traditional finite state machine. While the fFSM model provides lots of syntactic constructs for describing control flow, it has a lack of their formality and then difficulties in verifying the specification. In order to define the formal semantics of the fFSM, in this paper, firstly the hierarchical structure in the model is flattened and then the step semantics is defined. As a result, some important bugs such as race condition, ambiguous transition, and circulartransition can be formally detected in the model.

정보시스템 구축에 있어서 적절한 시스템 분석 및 설계를 위한 모델링 기법을 활용하는 것이 중요 과제이며, 이러한 시스템 모델링 분야에서 객체지향 기법을 적용하는 것이 업계의 표준으로 인식되어 가고 있다. 통합 모델링 언어로 불리는 UML은 시스템 개발 과정에 참여하는 모든 이들이 각자의 시각에서 이해할 수 있도록 각 분야의 설계도를 그릴 수 있는 표준을 제공하고, 그래픽 요소를 조합해서 다이어그램으로 나타낼 수 있는 장점이 있으며, 객체지향 시스템 개발그룹에서 표준으로 인정받고 있는 모델링 언어이다. IDEF3는 비즈니스 프로세서를 분석하고자 시도된 최초의 방법이고, 업무를 체계적으로 분석할 수 있으며, 쓰여지는 기호의 간편함과 명료함 때문에 쉽게 표현할 수 있는 장점이 있다. 본 논문에서는 신발을 수출하고 있는 중소기업의 반 정형화(semi-structured)된 수출/무역관리 업무 프로세서에 대하여, UML과 IDEF를 이용하여 분석하고, 이에 따른 시스템 개발 방안을 제시하고자 한다.

The UML(Unified Modeling Language) Class Diagram which is a part of structure of UML is fit for Object Modeling, and more recently, as the appearance of UXF(UML eXchange Format) UML Class Diagram by itself, can be exchanged in many other different system document. So this paper suggest the conversion system from UML Class Diagram to XML DTD. As this we can easily transformation and saving the UML Class Diagram that is the standard of Modeling Language to XML document which is so reusable. Also it can give a flexible method for the representation to the logical structure of document in various way because of converting XML DTD.

For increasing needs about web-based XML applications, there has been a lot of studies about WIDL, CDF and OSD that are related to XML. Especially, the OSD format describes software packages and their inter-dependencies that is widely used in a CDF file, IT uses different forms for representing relationships among software pakages, because there has not been proposed a method of object modeling about it until now. In this paper, we propose a modeling method for the OSD and CDF documents using UML relationships. It is a part of the project to merge XML, applications and convert thd OCD and CDF documents into an IML class diagram to generate OODB sheme. We can esily not only visualuze implementation and dependency relationships among software packages but also understand and transform logical structure of XML documents using modeling functions.

This study proposes the Web-based GIS system based on distributed object management and conceptualise system architecture and its methods specifications through UML(unified modeling language). By using class diagram and creating prototype based on UML and reverse engineering, our conceptual shape file model is proposed to illustrate an integrated architecture. Through system analysis and software configuration management, this study enables to not only improve pliable capabilities for problematic domains and increase abilities for analytical domains when user requirements are dynamic, but also assist effective and consistent maintenances of large software systems.
