Object-oriented software development methods are used to develop object-oriented software systems. Object-oriented systems are believed to habe better modularity, reusability, maintainability, and extensibility than systems modeled in conventional methods. Current object-oriented software development methods, however, are modeled in terms of procedural, functional, and structural models. There models cause problems such as tight coupling among activities, and uncontrolled access to global artifacts. In this paper, were introduce OMOS(Object-oriented software development Method for Object-oriented software System), an object-oriented modeling of object-oriented software development methods. Artifacts and their related activities are modeled as classes and objects. Development lifecycles are modeled as interactions among the objects. By modeling the software development method in an object-oriented way, OMOS achieves better reusability, flexibility, extensibility, and maintainability.

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.

The software development process (SDP) plays an important basic role in software engineering education. Every software is developed in accordance with a specific SDP which contains all phases of software development. SDP education helps students to understand the overall techniques and the process of software engineering. This paper introduces a software development methodology (i.e., process) - 'OOPT (Object Oriented Process with Traceability),' which was proposed for use in university software engineering classes. The OOPT is based on object-oriented software development, and it defines concrete requirements as well as outputs of each process/phases. It also contains the unit/system testing and a traceability analysis. We have used the OOPT in software engineering classes at Konkuk university for eight years. This paper conveys our experience as well as future extension and improvement plans.

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.
