MDD is suitable to satisfy constraints of development of mobile applications. So, there are various studies about applying MDD to the developments of mobile application but systematic development methods about UML profile for PIM/PSM of mobile applications and model transformation techniques are needed. This paper suggests that a development technique about UML profile for PIM/PSM of mobile applications and a model transformation techniques with the profiles. We classify stereotypes by the characteristics of mobile application to compose profiles and suggest development guidelines of profiles for PIM/PSM. On the suggested model transformation process, the PIM with the profiles is transformed to the intial PSM with the mapping rules and the PSM is transformed to the refined PSM with templates which reflected detailed information of a mobile platform. We developed a location based service mobile application with the suggested techniques on the Android platform and compared with other techniques to validate usefulness of the suggested techniques.

As a technique to enhance reusability for the created artifacts in software modeling process, the model driven method such like MDA has been applied. Unfortunately, the hierarchical and systematic MDA based development technique using UML is poor yet. This causes the problem that the MDA modeling with high consistency and reusability based on MDA metamodel is not being realized. To solve this problem, this paper proposes a MDA (PIM/PSM) component modeling technique using 2+1 view integrated metamodel. At first, the meta-architecture view model which can represents development process view and MVC view is defined. Then, the hierarchical integrated metamodels per view are addressed separately for modeling process and MVC at metamodel level on the hierarchy of the defined meta-architecture view model. These metamodels are defined hierarchically by layering the modeling elements in PIM and PSM pattern for UML models and GUI models. Appling the proposed metamodel to an ISMS application system, it is shown as a component modeling case study based on MDA. Through this approach, we are able to perform a component model with consistency and hierarchy corresponding to development process and MVC way. Accordingly, this may improve more independence and reusability of model.

OMG에서 제안한 MDA는 시스템의 설계와 명세를 기술 플랫폼 독립적인 모델인 PIM으로 작성하고. 매핑을 통해서 실제 구현과 관련된 모델인 PSM을 만들어냄으로써 시스템을 보다 효율적으로 유지 및 통합할 수 있다. 이를 지원하기 위해 본 논문에서는 EDOC 프로파일 기반의 PIM 변환기를 제안하여 메타 모델 단위의 매핑을 통한 PSM으로 변환 과정의 자동화를 지원하고자 한다. 변환기의 입력인 PIM은 분산 컴퓨팅 환경에 대해 OMG에서 채택한 EDOC 프로파일을 적용하였으au, 매핑 결과인 PSM은 UML Profile for EJB를 적용하였다. 또한 자동화된 PIM 모델 변환을 위해 EDOC to J2EE/EJB 매핑 규칙을 정의하였으며, 이를 지원하는 도구를 구현하여 회의실 예약 시스템 예제에 적용시켜 검증했다.

MDA 기반 개발을 지원하는 도구를 사용하여 모델 변환을 수행하거나 또는 수동으로 모델을 변환하는 경우 두 모델간에 변환의 일관성 검증은 반드시 필요하다. 본 논문에서는 현재 개발 지원 도구에서 자동으로 수행되고 있는 MDA 핵심 개념인 모델 변환 가운데 한 가지인 PIM에서 PSM으로의 변환이 일관성을 유지하면서 정확하게 수행되었는가를 검증할 수 있는 기준으로 구성 요소간의 추적성과 데이터 타입변환의 정확성을 도출하였다. 이에 따라 모델간의 일관성을 검증하기 위한 규칙을 추적성과 정확성으로 구분하여 제시한다.

MDA(The Model Driven Architecture)는 모델을 기반으로 시스템을 개발하는 방법이다. 현재 MDA에서 제안하는 대표적인 모델링은 PIM, PSM으로 두 종류의 모델링 영역이 필요하지만, 적용 플랫폼에 따라 다양한 PSM이 필요하므로 모델링 영역이 확장된다. 또 MDA가 발전하면서 PIM과 PSM이 상대적인 개념임을 인식하면서 모델링 영역은 더욱 더 늘어날 예정이다. 다양한 모델은 다이어 그램으로 표현되고 이를 지원하기 위해 메타 편집 기능이 필요하다. 본 논문에서는 MBA 환경에 필요한 다양한 모델을 표현하기 위해 다이어그램을 생성하는 방법을 기술한다.

This paper proposes a development tool to efficiently develop node software for various operating system platforms in a sensor network. The proposed tool consisted of several modules, such as writing graphical model diagram, PIM and PSM design, code generation, and deployment file generation. Through the proposed tool, the users can graphically draw a sensor network model and design the PIM and PSM of the node software by setting the values of the predefined attributes. The source code of the node software is generated automatically from the PSM using the code templates of the target platform. The deployment files for installing node software on each node are generated automatically. The proposed tool helps the users to develop node software easily for a range of target platforms, even though they do not have details of the low-level information for a sensor network.

모델을 중심으로 하는 MDA 개발 환경에서는 많은 모델링이 필요하다. 기본적으로 MDA의 기본 단계인 CIM, PIM, PSM 단계의 모델링이 필요하며, 각 단계에서 추상화 수준, 뷰포인트 등에 따라 다양한 다이어그램이 필요하다. 현재 MDA 의 PIM과 PSM 을 상대적인 개념으로 인식하기 때문에 MDA의 단계는 더욱 확대될 것이다. 본 논문에서는 분산 환경에서 컴포넌트 기반 엔터프라이즈 시스템을 개발하기 위한 EDOC 프로파일을 중심으로 MOF 기반 모델링을 수행하는 방법과 프로토타입을 기술한다. OMG 의 제안한 메타모델 표준인 MOF를 이용하므로 JMI, MOF XMI, MOF IDL 매핑을 이용할 수 있는 장점을 갖게 된다.

OMG 가 시작한 MDA(Model Driven Architecture) 는 소프트웨어 개발자들사이에 빠르게 전파되고 있다. UML 은 OMG 에 의해 MDA 를 위한 언어로 선택되었는데, UML 은 PIM(Platform Independent Model)에서 PSM(Platform Specific Model)을 생성하기에는 충분하지 않다. 하지만, 이러한 PIM-PSM 변환을 가능한한 자동화할수 있는데 이 논문은 자동 코드 생성을 위해 UML 의 확장 방법인 Stereotype 과 Tagged-Value 에 대해 논하게 된다. 또한, Aspect-Oriented 접근을 위해서 AOP 로 확장된 UML 에서 비 AOP 언어로 코드 생성이 가능하게 되는 새로운 방법도 제안을 한다.

Being able to resolve huge problems deriving from integration of information systems in-house or business to business, the web service that uses the XML standard technology has recently taken a quick dominance the next generation e-business bases. It's one constant concern how to integrate, change, and maintain such systems as based on certain technologies according to the changes to information technology, which is on the ongoing process of evolution. To help solve those problems, OMG suggested a new software architecture called MDA(Model Driven Architecture). MDA runs a process that establishes a platform independent model(PIM), which is an analysis model used as part of the existing development procedures, and automatically converts it into a platform specific model(PSM), a design model, based on the established PIM. Such automatic conversion has lots of benefits including easy support for diverse platforms, reducing the coding time that usually consume a great deal of the developer's effort, and facilitating quality control in the aspect of development processes. By applying the MDA development process to a new web service development, you can choose web service as the target platform at the PIM of MDA and express PSM with a web service model, WSDL. This study set out to classify the web service development or integration processes by the provider md requester to identify the types of web service development processes, and to apply the MDA development process to web service development, thus suggesting a new kind of web service development process that can be referred to by both the web service provider and requester.

The system development approach method of the new paradigm, as being standardizing MDA(Model Driven Architecture) in OMG(Object Management Group), the core technique of MDA definite technique structure for system materialization focusing on Model, is to build the design and the statement for system in PIM(Platform Independent Model), Materialization technique, and to build PSM(Platform Specific Model) adapt to materialization environment, and then to be the technique transforming into language Platform suitable to materialization environment. It includes MOF(Meta-Object Facility), UML, XMI(XML Metadata Interchange), CWM(Common Warehouse Metamodel), the core of MDA. Though these operations MDA support automatic tools product the practicable system after carrying out transform operation with the above information. In this thesis, it will be approached how to design and materialize the Bachelor management system based on MDA and the importance of modeling should be emphasized by applying to the approach method based on MDA. It should be suggested how to develop software efficiently, written it out in PIM, and suggested the process transforming PSM into EJB by J2EE Platform. The system is designed and implemented using automatic tool, edit machine(Together Architect 2006 for Eclipse, Edit plus2) supporting MDA and Database Modeling tool(ER/WIN 4.1). In conclusion, it should be suggested the efficiency analysis result for development process of traditional and based on MDA.
