Recently, object-oriented concepts and technology are on the leading edge of programming language and database systems research, and their usefulness in those contexts has been successfully demonstrated. The adoption of object-oriented concept to the design of model bases has several benefits. From the perspectives of object-oriented approach, models in a model base are viewed as object which encapsulate their states and behaviors. This paper focuses on the design of an object-oriented model base that handles various resources of DSS(data, knowledge, models, solvers) in a unified fashion. For the design of a model base, we adopted Object Modeling Techniques(OMT). An object model of OMT can be used for the conceptual design of an overall model base schema. The object model of OMT provides several advantages over the conventional approaches in model base design. The main advantage are model reuse, hierarchical model construction, model sharing, meta-modeling, and unified model object management.

Object-oriented programming goes on increasing in many areas, as its advantages of flexibility and ease of maintenance have been recognized. As in usual programmings, the productivity and flexibility of CACSD package can be improved by adopting object-oriented programmin. This paper describes our efforts to implement an OO-CACSD(Object Oriented CACSD) package for control system design and simulation. Since the proposed OO-CACSD is based on the modularity, portability, reuseability, and matrix-oriented data structure, a control system can be not only modeled and simulated but also maintained easily.

Object-Oriented design method decomposes the program into object that establish the relationship between objects. It is the technique of object centered decomposition unlike function oriented legacy system. Since existing Object- Oriented design method doesn't fully explain of the design method of module and decomposition, and need to implement the Object-Oriented software as a total system init. It has many problems that whole object design method and application programs should be analyzed for the understanding an Object-Oriented software component. Therefore, this study provides a procedure for Object-Oriented module design and criteria of decomposition to practically support the complex and large system development. Futhermore, it shows a consistency between design model and implementation through a case study applying these module decomposition criteria to the real system.

As object-oriented development technology that increases extensibility and reusability has been widely spread, it can shorten development period and enhance quality by reusing verified object-oriented artifacts. Thus we can construct high quality component-based system at short time transforming component-based model using verified object-oriented artifacts. In this paper, we propose techniques to transform available object-oriented design model into component-based model using formal specification techniques in order to increase accuracy of transformation. First, formal specification language for component is defined for formal specification of component-based design. And, techniques for formal specification of object-oriented design using Object-Z, a formal specification language, is proposed in structural, functional, and dynamic aspects. Next, we present techniques for transforming formal specification of object-oriented design into formal specification of component-based design. Through a case study we apply the proposed transformation techniques and show the transformation process of object-oriented formal specification into component-based formal specification.

The notion of object oriented analysis and design in software engineering has many rewards that aid the programmer to have an understanding of and improve the program efficaciously. Object oriented metrics helps rather a lot to a programmer or developer to comprehend and unravel the thing-oriented trouble readily and exactly. Object oriented metrics helps in examining the usefulness of object oriented applied sciences or in simple phrases Object-oriented metrics depict characteristics of object-oriented programming. The intention of this paper is to have an understanding of concerning the UML, Object oriented evaluation and design and the way it plays in UML.

Object-orientation has been proposed as a promising software process innovation to improve software productivity and quality. It has not been understood clearly, however, what factors influences the diffusion of object-oriented technology in organizations. A research model was formulated and hypotheses were generated based on the literature of information technology implementation and software process innovation. To test the research hypotheses, a questionnaire survey was conducted. The results based on 121 responses from Korean companies revealed that project characteristics, use of external experts, and number of development projects are significantly related to the diffusion of object-oriented analysis and design and object-oriented programming. Innovation champion is positively related to the diffusion of object-oriented analysis and design, whereas it is not related to the diffusion of object-oriented programming language. Only project complexity was significantly related to the diffusion of visual programming language. On the other hand, organizational size was not significantly related to any object-oriented technology in this study.

The various kinds of object-oriented methodology were provided for the development of flexible software. However, they do not automatically make the reusable and robust Object-Oriented software systems. The Object-Oriented mechanism is simply used as the means to obtain the aim. We have heard many complaints from the developers that methods did not give concrete design guidance. Methodologists' effort and make reusable information in the design phase. The relation between the Object-Oriented methods and the design patterns is mutually complementary, and they play a role as a valuable design guidance in the development of the Object-Oriented system. This paper show the interaction between OMT which is most well-known in the Object-Oriented Methodology and Facade, Mediator and Observer designed by Gamma. We suggest the clear solution for concrete design knowledge and reusability of them by applying design patterns to Object-Oriented Methodology.

An integrated structural design system can define and process complex design information that occurs in each of the design stages for flexible cooperation. It can also reduce human error on sequential design steps: preliminary design, analysis and detailed design. Therefore, it's very important to have consistent semantic expression and procedure for structural design information that has complex relationships. In this study, we introduce the object-oriented concepts and object-oriented database thechnique that provides high level semantic expression in order to develop an integrated structural design system.

This paper proposes a design procedure to develop the object-oriented simulator of port container terminal. The design methodology uses an object-oriented approach to support an object-oriented simulation and the design procedure consists of object scheme and event scheme. The object-scheme is a procedure to determine the structure of material flow objects and information flow objects and a relation diagram between objects that have attributes and methods. The event scheme is a procedure to define methods and to connect messages of objects. We assume that the container terminal system consists of gate, container yard, and berth and the equipment used in the container terminal are container cranes, transfer cranes, yard tractors, and trailers.

Most object-oriented analysis and design methodologies are based on structured analysis and information modeling and are using for intuitive analysis and design models based on object-oriented programming languages. Therefore there are many problems such as when a system is implemented incorrect semantics and inconsistency between models.This paper submits a decomposition and design method for object, dynamic and functional module of the methodology of a new system development life-cycle. Thus, we present a new system development life cycle, and suggestsa object-oriented design methodand standards of module decomposition for the decomposition of object, dynamic, functional models due to object-oriented design procedures and specifications. This proposed method enables developers to reflect user's software requirements conveniently. We prove the validity and practicality of this object-oriented design method through implementing a real-system.
