  • This paper describes a design driven approach to drive intelligent test plan generation based on adaptive use case (3,5). Its foundation is an object-oriented software design approach which partitions design schema into design architecture of functional components called “design component”. A use case software development methodology of adaptive use case approach developed in I.I .T is employed which preserves this unit architecture on through to the actual code structure. Based on the partition design schema produced during the design phase of this methodology, a test plan is generated which includes a set of component and scenario based test. A software metric is introduced which produces an ordering of this set to enhance productivity and both promote and capitalize on test case reusability, This paper contains an application that illustrates the proposed approach.

  • Research issues in software engineering in recent may be object oriented methodology and software quality. Since Halstead has proposed metric-software science in 1977, software quality area has been studied in steady but inactively until 1980s. As international standards such as ISO 9000-3, 9126 were enacted in 1990s early, interest in software quality is increased but many problems such as how to validate metric, measure quality or apply metric are remained. This paper proposes software quality metric methodology which software developer or project manager can use in measuring quality and validating metric during software development. The methodology is classified by several phases: establishment of quality requirement, identification of quality metric, data collection, metric implementation, metric validation. In order to show its applicability, test program, metrics and data are applied to each phase of the methodology. Consideration of this methodology as a methodology for software quality measurement similar to development methodology for software development is needed.

  • Todays computer communication technology let people to do many unrealistic things possible and the use of those technologies is becoming increasingly prevalent throughout the military operation. Both DIS and ADS are welled defined computer aided military simulations. This study discusses a simulation of stochastic combat network modeling through Internet. We have developed two separate simulation models, one for clients and another for server, and validated for conducting studies with these two models. The object-oriented design was necessary to define the system entities and their relationship, to partition functionality into system entities, and to transform functional metrics into realizations derived from system component behaviors. Heterogeneous forces for each side are assumed at any battle node. The time trajectories for mean number of survivors at each node, some important combat measures, and relative difference computations between models were made. We observe and may conclude that the differences exist and some fo these are significant based on a limited number of experiments.

  • 객체 지향 설계를 재구조화하기 위해서는 메소드와 속성들 사이의 관계를 파악해야 한다. 메소드와 속성들이 동일한 클래스에 속하는지를 추론하는 과정은 클래스 자료 참조 분석과 메소드 호출 분석에 의존한다. 최근의 많은 소프트웨어들은 규모가 방대하고 복잡하여 개발자가 도구를 사용하지 않고 수작업으로 설계를 재구조화기 어려우며 또한 너무 많은 시간과 노력이 요구된다. 본 논문에서는 메트릭을 이용하여 객체 지향 설계를 자동적으로 재구조화하는 방법을 기술한다. 먼저 메소드, 속성, 클래스, 그리고 그들의 관계츨 추상화된 모델로 표시한다. 이 모델을 기반으로 객체 지향 설계를 정량적으로 측정할 응집도와 결합도 메트릭을 정의한다. 본 논문의 메크릭은 재고조화 과정 동안에 여러 다른 설계들을 효율적으로 비교하기 위한 유용한 기준을 제공한다. 기본 재구조화 행위들과 그 의미(semantics)를 정의하고 메트릭과 행위들을 사용하여 설계를 자동적으로 재구조화한다.

  • 최근 주목을 받고 있는 자바는 객체지향성을 가장 잘 반영한 언어이며 많은 연구 분야에서 사용되고 있지만 기존의 테스팅 도구들이 대부분 C++을 기본 대상 언어로 사용하기 때문에 자바에 적용하기 위한 테스팅 방법과 도구들이 부족한 것이 현실이다. 때문에 기존의 테스팅 도구들에 자바 프로그램을 적용하기는 까다로운 일이 아닐 수 없다. 본 논문에서는 기존에 연구되어진 객체지향 소프트웨어 메트릭스들을 자바에 적용하는 방법과 자바에 적용할 수 있는 새로운 메트릭스들과 자바프로그램의 구조를 보다 쉽게 파악하기 위한 분석지원 도구의 설계 및 구현에 대하여 연구하였다.

  • 소프트웨어가 복잡해지고 대형화됨에 따라 다양한 소프트웨어 측정 개발에 필요한 비용이 점차 증가하게 되었지만 지금까지 시도된 측정 기법은 정형화되어 있지 않고 다양한 측정 메트릭을 통해 소프트웨어를 측정한다고 해도 측정 결과의 비교와 분석을 통해 수치적 해석 데이터를 얻기가 어려웠다. 따라서 본 논문에서는 사용자의 사용 사례를 통해 패턴을 추출하고 이를 통해 실험 데이터를 만들어 실제 소프트웨어가 동작하는 도중 내부 모듈간의 동적인 관계를 측정할 수 있는 시스템을 제안하였다.

  • Object-oriented programming is often touted as promoting software reuse. However it is recognized that objected-oriented software often need to be restructured before it can be reused. refactoring is the process that changes the software structure to make it more reusable, easier to maintain and easire to be enhanced wit new functionalities. This paper desirbes experience gained and lessons learned from restructuring OODesigner, a Computer Aided Software Engineering(CASE) tool that supports Objects Modeling Technique(OMT). this tool supports a wide range of features such as constructing object modeler of OMT, managing information repository, documenting class resources, automatical generating C++ and java code, reverse engineering of C++ and Java cod, searching and reusing classes in the corresponding repository and collecting metrics data. although the version 1.x was developed using OMT(i.e the tool has been designed using OMT) and C++, we recognized that the potential maintenance problem originated from the ill-designed class architecture. Thus this version was totally restructured, resulting in a new version that is easier to maintain than the old version. In this paper, we briefly describe its restructuring process, emphasizing the fact that the Refactoring of the tool is conducted using the tool itself. Then we discuss lessons learned from these processes and we exhibit some comparative measurements of the developed version.

  • The development of automated quality evaluation tool is desperately needed to decrease the cost of maintenance, to measure quality of source program in developing course for the purpose of developing high quality software. Main goal in this paper is to develop the automated tool for software quality evaluation related with high quality and high reliability of software. In this paper, we proposed the four software quality model to evaluate software quality; functional -size model, understandability model, complexity model and object-oriented model. Also, we made a scanner and a parser to analyze the c and C++ source program and to produce the metrics and function value. The measurement value is statistically analyzed for the distribution of the measurement value. we can extracted the characteristics of measurement value and this one is assisted to make scores of software quality evaluation. Finally, we made a software quality evaluation tool to support software evaluation activities.

  • Web applications have different structural characteristics from conventional applications with the structural language or object-oriented language or 4GL. A web application typically consists of server-side script elements which run on web sewers, client-side script elements which run on the client web-browser, HTML elements that contains context. Therefore web applications developer concurrently uses 3 or more development language. Cyclomatic Complexity for Web Application(CCWA) metrics reflected composite complexity of each element. In this paper, we applied cyclomatic complexity for web application metrics with Complexity level indicator to web application. We applied it to 10 web applications that were developed in practical business. High complexity web applications classify into four type(MENU, FORM, CTRL, GEN). This paper has contributed to practical use of engineering approach for web application.
