Abstract
Abstract The purpose of this study is to provide a quantitative evaluation index of object-oriented software development productivity for EJB 3.0 and EJB 3.1. A lightweight container architecture is a newly-developed architecture in order to solve demerits that N-Tiers enterprise architecture has and to support merits therein. A lightweight container architecture is not as heavy as EJB(Enterprise JavaBeans) architecture is, whereas it provides all the functionality of the EJB container. However, there have been insufficient studies on a performance evaluation of EJB 3.0 and EJB 3.1 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 indeces and guidelines for a new specification released. Accordingly, there has been limited evaluation of software development productivity and on new innovations in a project. Therefore, this study designed and implemented a movie reservation system in EJB 3.0 and EJB 3.1, which was based on the same development platform environment. This study then intends to provide evaluation guidelines for an objective software development productivity cl LoC(Lineand standardization thereof by development platform environment.
