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.

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.

Since embedded software is very dependent for target hardware architecture, characteristics of the platform must be considered when designing the software. Furthermore, MPSoCs consists of heterogeneous hardware components that are specified in micro level. Thus mapping of embedded software for MPSoCs should be considered the characteristics. In this paper, we provide an approach to automatic mapping PIM (Platform Independent Model) of an embedded software to PSM(Platform Specific Model) for MPSoC(Multi Processor System On Chip) and verify its effectiveness with simulation. In the proposed approach, tasks are derived from an object oriented model based on the UML (Unified Modeling Language). And then the types of the derived tasks are identified. With the identified types and inter relationship between tasks, the tasks are assigned to appropriate heterogeneous hardware components. We expect that the approach improve accuracy of the assigning and concurrency of the deployed software.

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.

At present, new techniques based on different component reference models for the integration of component and system of different platforms, such as EJB and COM+, are introduced. The operation between the components in the identical component platform is realized by the composition at the source level. In case of the different component platform, however, it is impossible to use combined components in real condition although they are components of similar domain. In this paper we proposed a solution for the composition problem by using component transformation methodology based on model between EJB and COM+ components which are different components. For the composition between EJB and COM+ components, we compared and analyzed each reference model, then proposed the Virtual Component Model which is implementation independent and the Implementation Table for the mutual conversion. Reffering to the Virtual Component Model and the Implementation Table, we can generalize each Implementation model to the Virtual Component Model, make the Virtual Component Model which is implementation independent through the virtual component modeling, transform EJB and COM+ components selectively. Proposing the effective Model Transformation method to the different component platform, we can combine EJB and COM+ components.

이종의 컴포넌트 개발 플랫폼 및 다양한 구현 기술의 발달로 이들간의 상호 운용성 및 통합을 지원하기 위하여 OMG에서 채택한 MDA(Model Driven Architecture) 기반 소프트웨어 개발이 대두되고 있다. MDA 기반 소프트웨어 개발 방법에서 기본적으로 고려하고 있는 것은 새로운 컴포넌트 생성을 초점으로 하고 있어 이미 개발되어 있는 컴포넌트의 조립에 대한 고려도 요구된다. 따라서 본 논문에서는 MDA의 중심 개념인 플랫폼독립 모델(PIM： Platform Independent Model)과 플랫폼 종속 모델(PSM: Platform Specific Model)의 분리와 매핑을 통한 변환에 대해 조립하고자 하는 EJB 컴포넌트를 고려하여 플랫폼 독립 모델을 생성하고 이를 플랫폼 종속 모델로 변환하는 방법을 제안한다.

모델기반 아키텍처 MDA (Model Driven Architecture)는 소프트웨어 개발의 추상화 수준을 높이기 위한 최근의 개발 아키텍처이며 완벽한 이해성을 확보하기 위해서 구체적인 구현기술은 반드시 개발자에게 추상적으로 (encapsulation) 숨겨져야 한다. 즉, 개발자는 자동적으로 실행 가능한 시스템으로 변환하는 플랫폼에 구애 받지 않는 모델들 PIM(Platform Independent Model)만을 고려하게된다. 본 논문에서는 MDA 를 캠퍼스 안내 앱에 적용하여 개발함으로써 모바일 디바이스 및 OS 에 독립된 어플리케이션을 개발 방법론을 제시한다.

The Software Product Line (SPL) engineering is one of the most promising software development paradigms. With Feature-Oriented Reuse Method (FORM), reusable and flexible components can be built to aid the delivery of various software products such as mobile phone and digital TV applications based on commonalities and variabilities identified during Feature modeling. Model Driven Architecture (MDA) is also an emerging technology which supports developing software products to work on different platforms with platform independent models (PIM). Combining advantages of these two approaches is helpful to build a group of software products which share common Features while working on various platforms. As first step to combine FORM with MDA, we extend UML2.0 with profiles by which FORM architectures and parameterized Statecharts can be modeled. Secondly, we provide rules to examine whether Features are allocated at positions of elements of Statecharts consistently between a Feature model and a parameterized Statechart. Some rules are designed to check the consistency between FORM architectures and parameterized Statecharts. A case study on an elevator control system is provided to demonstrate the feasibility of our modeling approach and consistency checking rules.
