  • 유스케이스(Use Case)를 기반으로 하는 관점지향 소프트웨어 개발방법론(Aspect-Oriented Software Development, AOSD)은 사용자 중심의 시스템을 설계하는데 있어 매우 중요한 소프트웨어 개발방법론으로 부각되고 있다. 학습관리시스템(Learning Management System, LMS)은 사이버교육을 지원하는 핵심시스템이며, 다양한 요구사항을 제시하는 청소년층을 대상으로 하기 때문에 높은 유지보수성과 확장성을 필요로 한다. 본 논문에서는 관점지향 소프트웨어개발 방법론을 6단계 모델링 방법을 통해 사이버 교육을 위한 학습관리시스템에 적용하였다. 적용 결과 학습관리시스템에서 횡단관심사의 모델링을 통한 관점지향 소프트웨어 개발은 유스 케이스 중심으로 모델링되어 사용자 중심의 시스템 유지보수성과 재사용성을 높일 수 있음을 보였다.

  • Currently, software development methods have been advanced to service-oriented from component-oriented, to component-oriented from object-oriented. The component-oriented and service-oriented software development methods are analyzed by object-oriented UML model. So, the efficient analysis method for object-oriented UML model needs. In this paper, we suggest the analysis guideline and process based on event using Input Data-Process-Output Data Table for identifying use cases and classes efficiently. And the suggested method complements the problems depending the developer's perspective and experience.

  • Even though context is the most important feature in context-aware systems, the existing requirements engineering cannot support methodology for elicitation and specification of contexts. In this paper, we propose a requirements elicitation method and a requirements specification method for context-aware systems. Our requirements elicitation method is a 6-stepped, incremental, and iterative process. At the beginning steps in the process, we identify the requirements for business logic. Afterwards, we gather the requirements for context logic, model contexts, and identify subsystems. For requirements specification, we suggest a context-aware use case diagram, a context diagram for context modeling, and a context-type-use-case-dependency diagram for the traceability of use cases on the change of context types. We also introduce a case study that we apply our approaches to a real system, and a qualitative evaluation of our approaches. Our study will help stakeholders to efficiently elicit requirements for context-aware systems and to specify them clearly.

  • In this paper, we implement the XML and data modeling by the UML tool, in which the class diagram is constructed from the sequence diagram after making the use case diagram. For the XML modeling. the guiding line will be presented to transform the UML class into the XML document, and then an example to draw the XML DTD from the UML class will be also shown. Furthermore, through the proposed data modeling, the integrated design methods for the transformation of the UML class into relational database schema. object-relational database schema and object-oriented database schema also will be proposed. Finally, we will be presented schema for each database system.

  • This paper presents a UML CASE tool for collaboration work between remote place. It configured functions to support collaboration work and it applied framework concept to increase extension and reusability. It also constructed UML CASE tool based on framework. It result in not only reflecting various stakeholder's opinions but it also contributing to integrated and consistent modeling.

  • Recently, the need for accessing information from anywhere at any time has been a driving force for a variety of mobile applications. As the number of mobile applications increases rapidly, there has been a growing demand for the use of Service Oriented Architectures(SOA) for various applications. Mobile based SOA offers a systematic way to classify and assess technical realizations of business processes. But mobile has severly restricted range of utilizing services in computing environment and more, a mobile computer is envisioned to be equipped with more powerful capabilities, including the storage of a small database, the capacity of data processing, a narrow user input and small size of display. This paper present mobile adaption method based on SOA to overcome mobile restriction. To improve mobile efficient we analyzing mobile application requirement writing service specification, optimizing design, providing extended use case specification which test use case testing and testing service test case which derived from service specification. We discuss an mobile application testing that uses a SOA as a model for deploying discovering, specifying, integrating, implementing, testing, and invoking services. Such a service use case specification and testing technique including some idea could help the mobile application to develop cost efficient and dependable mobile services.

  • In this paper, we implement the XML modeling and data modeling by the class diagram that is made by the use case after drawing out the sequence diagram. For the XML modeling, the guiding line to map the UML classes on the XML document will be presented. Then, an example to generate the ie DTD from the UML classes will be shown under the presented guiding line. In the data modeling, the transformation method from the In classes into the object-oriented database also will be proposed. Finally, we will give an example developed by the Proposed transformation method.

  • In this paper, we propose an object-oriented modeling technique using UML(Unified Modeling Language) for accessibility of user and efficiency of facilities under Web-based integrated manufacturing management system application. For this, we first collect user requirements and related technology of integrated manufacturing system, and then design proposed system considering business flow and various essential design part(class, component, package, use case, and etc) to reduce system risk as well as communicate peacefully between developers in system redevelopments. Additionally, we develop database of manufacturing master code, check management, repair management and error management for proposed systems. Finally, we design and implement our three main modules; manufacturing check module, manufacturing repair module, manufacturing error module under Web-based environments with JSP language.
