The purpose of this study is to provide a quantitative evaluation index of object-oriented software development productivity for EJB 3.x. The lightweight container architecture is a newly-developed architecture in order to solve demerits that N-Tiers enterprise architecture has and to support merits therein. However, there have been insufficient studies on a performance evaluation of EJB 3.x on an identical platform. Since a quantitative analysis has been performed only with respect to a partial LoC(Line of Code) analysis, there have been insufficient objective evaluation indices and guidelines for a new specification released. Accordingly, there has been limited evaluation of software development productivity and on new innovations in a project. This study then intends to provide evaluation guidelines for an objective software development productivity comparison by development platform environment.

This paper aims to design and realize movie reservation system based EJB 3.1 with Enterprise of Standardization. This architecture, such as the EJB, but not heavy, to provide all of the architecture is possible. The lightweight container architecture is most often used in business EJB 3.1 is well-known architecture. Therefore, this research has the N-tier enterprise architecture to solve the advantages and disadvantages developed to support the latest EJB 3.1 architecture based on the design and implementation of a movie reservation system.

This paper proposes a software development evaluation index for the productivity related to Spring 2.5 and EJB 3.0 with same lightweight container architecture. Spring is a known successful open source standard model for lightweight container architecture. EJB in an enterprise environment as a standard framework is most commonly used in production. However, there is no comparison research about the performance of Spring 2.5 and EJB 3.0 with same identical platform. Quantitative analysis is supported as a part of LoC(Line of Code) analysis. There is a limit to develop the updated software with no the specific evaluating index for the productivity of the software. In this study, the development platform environment based on the same database schema system Spring 2.5 and EJB 3.0 is in the design and implementation. In addition, comparison and standardization of software development productivity assessment is to provide guidance.

  This paper proposes an object-oriented software development guidance and an evaluation index for the productivity related to EJB(Enterprise JavaBeans). EJB is a known successful standard model for LSDO(Large Size Distributed Object). However, there is n

In this paper, we propose an approach object oriented software development guidance and evaluation index for the productivity related to EJB(Enterprise JavaBeans) with J2EE development platform. In the digital convergence life, EJB become known success standard model of size distributed object. However, the EJB specification of 2.0 and 3.0 is lack of software development productivity comparison research in an identical platform until now. In addition, quantitative analysis support and try a part of LOC(Line of Code) analysis. Therefore, it limited a new attempt of software development productivity evaluation. Our approach is objective validity of the new EJB Specification after presenting of analysis of quantitative evaluation index in the same platform related with EJB 2.0 and 3.0. Base on the result, it suggests objective software development productivity research guidance.

인터넷 기술의 발전과 함께 급진전한 디지털경제는 그 적용분야에 따라 B2B, B2C, A2B등의 많은 부류를 형성하였다. 또한, 고객의 요구사항에 맞추어 전자상거래 시스템 구축기술도 객체지향기반에서 컴포넌트기반의 개발방법으로 도입되고 있으며, 개발환경은 기존의 C/S(Client/Server)환경에서 3-Tier, 웹 기반 아키텍처등으로 변화, 도입되고 있다. 이러한 배경으로 본 논문은 전자상거래에 사용될 수 있는 좌석 예약 및 확인 시스템을 다중서버환경에서 구현하였다. 이는, 분산환경에서 효율성을 높이기 위해 해당 중요 로직은 서버 컴포넌트 모델인 EJB를 활용하였고, Main Server를 위해 Resin Server환경의 Servlet을 이용한JSP와Java를 통하여 구현하였다. 따라서, EJB를 이용한 독립 컴포넌트를 통하여 전자상거래 시스템 로직사이의 독려성을 높였으며, 분산된 EJB서버를 통하여 해당 메소드를 호출함으로써 서버의 부하를 줄이고, 각 로직자원들을 효율적으로 관리할 수 있도록 하였다.
