  • 객체지향 모델은 구조적 모델에 비해 모듈성, 재사용성, 유지보수성, 확장성 등의 장점을 제공한다. 이러한 이유로 객체지향 소프트웨어 개발 방법들을 정보 시스템 개발에 광범위하게 적용되고 있다. 그러나 현재의 객체지향 소프트웨어 개발 방법들은 목적 소프트웨어 시스템의 객체지향 모델링을 지원할 뿐, 방법론 그 자체는 구조적 및 절차적 체계를 기반으로 하고 있다. 본 논문에서는 객체지향 소프트웨어 개발 방법론을 객체지향적으로 모델링한 OMOS(Object-oriented software development Method for Object-oriented software System)를 제시한다. OMOS에서는 개발 산출물과 관련된 활동이 객체로써 모델링 되며, 개발 생명주기 프로세스가 객체간의 상호작용으로 모델링 된다. 소프트웨어 개발 방법론의 객체지향적 모델링은 방법론 자체의 재사용성, 유연성, 확장성, 유지보수성의 용이성 등의 장점을 제공한다.

  • Software quality is classified by quality of process and product. In experience of Quality Management, it is known that quality level of product as it depends on goodness and badness of process and organization. As a result, improvement of software process has been important subject. According as this trends, ISO 12207 is publicated as standard of software life cycle process by ISO. For UML based object oriented development process, it is necessary that we should research detailed definition of activity and task of ISO 12207 process which is added, deleted or tailored in according to organization and project characteristics. In this thesis, by according with ISO 12207 software life cycle process, UML based object oriented development process is proposed. This process is composed of 7 steps and 19 activities including development phase, activity and product to improve quality of reliability. Usefulness of object oriented process for improvement of software quality is proved at three ways, which are comparative analysis of process characteristics, SPICE process evaluation and SPICE rick analysis.

  • 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.

  • Recently, the computer software technology is not keeping pace with the increasing demand of application software development and rapid changes in business environment. To overcome this "software crisis", many researchers have studied the methodologies to improve the productivity in software development and the flexibility of software usage. Among these methodologies, the most promising and intensively studied methodology is the Object-Oriented Approach The purpose of this study is, therefore, to examine the applicability of the Object-Oriented Approach for improving productivity and flexibility in Management Information Systems development. For an application, we selected a financial planning model, especially focusing on the budgeted income statement. In this thesis, we identified relevent objects in the budgeted income statement, and represented them in the object models. By implementing these object models using C++ language, we evaluated their adaptability in the budget-making process, and showed, by comparing them with the existing Planning '||'&'||' Modeling Languages such as IFPS(Interactive Financial Planning Saystem), their practicability in Management Information Systems. The results of this study are as follows: First, the same object models can be used in making the budgeted income statement both in the department level and in the corporate level. Second, the object models provide the flexibility and extensibility of an application program in case of the changes in business environment. Third, the Object-Oriented Approach is a practical methodology to improve the productivity and cut down the maintenance cost of application software development.t.

  • 소프트웨어 개발 프로세스(Software Development Process: SDP)는 소프트웨어공학 교육에서 가장 기초적이며 중심적인 역할을 한다. 모든 소프트웨어는 개발의 시작부터 마지막까지를 모두 포함하는 특정 SDP에 기반해서 개발된다. 따라서, SDP 교육은 소프트웨어공학의 제반 기술에 대한 이해를 도울 수 있다. 본 논문은 대학의 소프트웨어공학 수업에서 활용할 수 있는 소프트웨어 개발 방법론(프로세스)인 OOPT(Object Oriented Process with Traceability)를 소개한다. OOPT는 객체지향 소프트웨어를 개발하기 위한 방법론으로서, 각 단계마다 구체적인 요구사항과 산출물을 정의하고 있으며, 단위/시스템 시험 및 추적성 분석 등의 추가적인 내용들도 포함하고 있다. 본 논문은 OOPT에 대한 적용 사례로서 다년간의 건국대학교 컴퓨터공학과 소프트웨어공학 관련 수업들을 소개하고 있으며, 향후 개선 및 발전 방향을 포함한다.

  • Purpose: The purpose of this study is to identify the object-oriented metrics which have strong impact on the reliability and fault-proneness of software products. The reliability and fault-proneness of software product is closely related to the design properties of class diagrams such as coupling between objects and depth of inheritance tree. Methods: This study has empirically validated the object-oriented metrics to determine which metrics are the best to predict fault-proneness. We have tested the metrics using logistic regressions and artificial neural networks. The results are then compared and validated by ROC curves. Results: The artificial neural network models show better results in sensitivity, specificity and correctness than logistic regression models. Among object-oriented metrics, several metrics can estimate the fault-proneness better. The metrics are CBO (coupling between objects), DIT (depth of inheritance), LCOM (lack of cohesive methods), RFC (response for class). In addition to the object-oriented metrics, LOC (lines of code) metric has also proven to be a good factor for determining fault-proneness of software products. Conclusion: In order to develop fault-free and reliable software products on time and within budget, assuring quality of initial phases of software development processes is crucial. Since object-oriented metrics can be measured in the early phases, it is important to make sure the key metrics of software design as good as possible.

  • In this paper, we present an abstract object-oriented plat-form model .suitable for the real-time distributed telecommunication system. The proposed platform is constructed upon the extended version of the real-time, distributed operating system, SROS(Scalable Real-time Operating System), that is developed at ETRI and successfully operated in the ATM switching system for several years. The object-oriented software development and maintenance methodology will resolve the current software crisis in the area of telecommunication and switching systems due to the everlasting maintenance about the huge amount of the existing software and the ever increasing needs for the better and new communication services. In general, an object-oriented software platform realizes the object-oriented methodology and possesses many good aspects like high productivity, better reusability, easy maintenance, et at. The platform is also designed to present the distributed multimedia service in addition to real-time event delivery. Recently, we have been implementing a couple of prototype bated on the proposed platform. Reflecting the evaluation results from these prototypes, the final platform specification will be determined.
