XML을 이용한 애플리케이션이 핫 이슈로 부각되고 있는 현재, 다양한 분야에서 XML 문서로의 변환을 모색하고 있다 많은 시스템 설계자들이 애플리케이션이나 시스템을 분석하는데 있어서 UML은 보편적으로 사용되는 모델링 언어일 것이다 또한 최근에는 모델링 언어인 UML을 XML DTD로 변환시키는 다양한 방법론들이 제시되고 있으나, 이러한 방법론들은 UML을 XML DTD로 변환시킬 경우 어느 정도의 정보의 누락과 변질이 발생하게 된다. 이렇게 누락되는 정보를 제대로 XML 문서로의 변환을 위하여, 본 논문에서는 두 가지의 모델링 기법을 사용하여 UML을 XML DTD로의 변환을 제안하였다. 변환 방법으로는 첫째, UML 모델의 각 부분을 XML로 변환하는 기법을 정리한 XML 변환 기법들이며, 둘째로는 UML로부터 XML DTD를 생성시키는 방법이다. 위의 방법을 이용하여 UML을 XML DTD로의 변환을 하고자 하였다. 변환시 UML 다이어그램의 다양한 정보를 DTD에 포함 시켜야 하므로, UML에 나타나 있는 여러가지 경우가 포함되어 있는 다이어그램을 선택하였다. 이렇게 두 가지의 기법을 사용하면 UML을 XML DTD로 변환하는데 정보의 손실을 최소한으로 줄일 수 있다.

A conceptual model can be used to manage complexity in both the design and implementation phases of the system development life cycle. Such a model requires a firm grasp of the abstract principles on which a system is based, as well as an understanding of the high-level nature of the representation of entities and processes. In this context, models can have distinct architectural characteristics. This paper discusses model multiplicity (e.g., unified modeling language [UML]), model singularity (e.g., object-process methodology [OPM], thinging machine [TM]), and a heterogeneous model that involves multiplicity and singularity. The basic idea of model multiplicity is that it is not possible to present all views in a single representation, so a number of models are used, with each model representing a different view. The model singularity approach uses only a single unified model that assimilates its subsystems into one system. This paper is concerned with current approaches, especially in software engineering texts, where multimodal UML is introduced as the general-purpose modeling language (i.e., UML is modeling). In such a situation, we suggest raising the issue of multiplicity versus singularity in modeling. This would foster a basic appreciation of the UML advantages and difficulties that may be faced during modeling, especially in the educational setting. Furthermore, we advocate the claim that a multiplicity of views does not necessitate a multiplicity of models. The model singularity approach can represent multiple views (static, behavior) without resorting to a collection of multiple models with various notations. We present an example of such a model where the static representation is developed first. Then, the dynamic view and behavioral representations are built by incorporating a decomposition strategy interleaved with the notion of time.

Unified Modeling Language (UML) is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems. On the other hand, XML, which is a meta-language, provides meta-data types for representing and string objects. It make software development easy because it can represent various information and share information about the software analysis and design between developers, In this paper, we apply BitWiz, one of automated software generation systems, to a bid application and analyse this in UML point of view. Also, we briefly introduce an XML documentation from UML products and a verification method of XML documents from UML products.

In company with the demand of powerful processing units for embedded systems, the method to develop embedded software is also required to support the demand in new approach. In order to improve the resource utilization and system performance, software modeling techniques have to consider the features of hardware architecture. This paper proposes a partitioning technique of UML-based software models, which focus the generation of the allocatable software components into multiprocessor architecture. Our partitioning technique, at first, transforms UML models to CBCFGs(Constraint-Based Control Flow Graphs), and then slices the CBCFGs with consideration of parallelism and data dependency. We believe that our proposition gives practical applicability in the areas of platform specific modeling and performance estimation in model-driven embedded software development.

As the complexity of software development is increasing due to networking, multimedia, and diverse system architecture, the need for effective software development methodology is increasing. Especially, due to software standard and internalization of software market, it is necessary to accept international quality such as ISO 9000-3. In addition, object oriented development methodology is required due to rapid propagation of OO technology and standardization. Recently, UML was accepted by the OMG as standard object-oriented modeling language for distributed environment. When we UML was accepted by the OMG as standard object-oriented modeling language for distributed environment. When we develop Java and CORBA-based software, often UML is applied to Java and CORBA-based projects. However, current structural or OMT-based object-oriented methodologies. In this paper, we proposed UML-based development and concrete guidelines for each phase in order to apply UML to software development practically and effectively. Also, we define the transition guidelines and semantics between various development tasks. In addition, the analysis and design techniques of user interface and system development techniques needed in Web application development are presented.

In this paper, we propose a Model Driven Development using UML(Unified Modeling Language) in an efficient Combat System Software development methods. UML is managed by the OMG (Object Management Group) as a Unified Modeling Language. Recently, In developing the software for the system, development time is contrary to a short, while it must meet a number of requirements of our customers. If you develop a non-efficient software early, the structure of the software become more complex in proportion to the number of requirements. As a result, a serious problem in the system, such as an increase in defective products due to the lowering of the reliability and communication problems between the developer has occurred. To overcome those problems, the aim of this paper is to develop a reusable high efficient Combat System Software by applying Model-Centric Development (Not Code-Centric Development). If Combat System Software development method using the UML proposed in this paper is used, easy communication among developers can help reduce the serious errors in systems. Also, it has the advantage that the future needs of software maintenance/repair become easy by using high readability object Model.

This study is redesigned library acquisition process to migrate library offline process to online applying the concepts of BPR(Business Process Reengineering), Business Process and Workflows in electronic commerce, and UML that is a one of visual modeling methods was applied to new model form software development. The new model can be processed library’s acquisition process efficiently and rapidly. And library and information center would migrate their back office work from offline to online using this model, so that new roles for librarian in the digital age will be created. The directions of digital library research should be accepted various application technologies like electronic commerce to get synergy effect in the near future.

현재까지는 실시간 임베디드 소프트웨어 개발을 위한 효율적인 소프트웨어 모델링 언어가 부족하다. 그런데 모델 자체가 코드처럼 수행 가능한 통합 모델링언어를 xUML(Executable UML)이라 한다[2,4,7]. 이는 기존의 UML x.x에 실행과 관련된 개념과 시간에 관련된 규칙을 더한 것이다. 다시 말해 xUML의 모델은 실행과 테스트, 디버깅이 가능하다[2,4]. 본 논문에서는 기존의 UML x.x버전들과 xUML이 실시간 임베디드 소프트웨어를 모델링 하는데 적합한지를 비교/분석한 후, 임베디드 소프트웨어 모델링에 xUML을 적용하고자 부족한 면을 보완 및 확장하였다. 확장된 xUML의 노테이션은 병렬과 실시간 처리까지도 표현이 가능하도록 제안하였다. 사례 연구로서 두개의 터치센서로 동작하는 실시간 임베디드 시스템의 모델링을 보여준다.

온톨로지는 에이전트가 지식 레벨 메시지 교환을 위해 사용하는 용어를 정의하는데 중요한 역할을 수행한다. 객체지향 모델링 중 특히 UML은 소프트웨어 공학 분야에서 많은 발전이 이루어져 왔으며, 대부분의 상업용 도구들에 의해 지원될 수 있다. 따라서, 에이전트 시스템에서 온톨로지 표현을 위해 UML을 사용한다면 에이전트 기반 시스템 개념의 이해를 돕는데 매우 효과적일 것이다. 본 연구는 온톨로지 모델링을 위해 UML 사용의 가능성을 제시하고자 한다.

비즈니스 정보 시스템 개발을 위한 요구사항 분석은 시스템의 결과를 좌우할 수 있는 중요한 과정으로 인식되고 있다. 따라서 대부분의 소프트웨어 개발방법론에서 사용자의 요구사항을 분석하기 위해 주로 사용되고 있는 UML 기반의 Use Case 모델링의 절차와 분석과정에서의 문제점에 대하여 살펴보고, 또한 전반적인 UML 의 문제점을 조사해봄으로써 시스템 개발을 위하여 UML 기반의 모델링을 적용하여 분석할 경우 고려해야 될 사항들을 미리 점검해 볼 수 있도록 지침을 제공하고 자 한다.
