摘要
LCAT(Life Cycle Assessment Tool)数据库设计的主要任务是按照生命周期评价工具的要求,设计一个结构合理、使用方便、效率较高的环境工程数据库。数据库设计得好,可以使整个应用系统效率高、维护方便、使用简单。反之即使是最佳的应用程序,也无法弥补数据库设计时的某些缺陷。本文介绍一种逻辑层次连接的环境工程数据库设计方法。即以层次分析为主,以连接关系为基础,结合面向对象技术方法进行环境工程数据库设计的方法。
It designs an environmental engineering database with rational structure, convenient use and upper efficiency, which is based on the life cycle assessment tool requirements, and is recognized as a key solution towards the LCAT (Life Cycle Assessment Tool) database design. Well designed database can make the whole system more efficient and more convenient to maintain and contrariwise, even an optimal application can not offset the defect made during the database design. This paper presents a methodology of logical hierarchy-link for environmental engineering database design, i.e. a method of environmental engineering database design with logical layering and links of object-oriented techniques.
