摘要： 并行工程（CE）的信息种类繁多，结构复杂，并且数据量非常大，需要存储在异构分散的数据库中，为方便应用和各种CE工具的集成，需对它们进行统一管理。信息资源字典系统（IRDS）从广义的概念上支持三模式结构，是CE信息集成的有效工具。文章介绍一个IRDS系统的开发，它的有关概念，三模式结构及在CE信息管理中的应用.

Abstract: Since the application systems and the structures of Concurrent Engineering (CE) informaion are greatly differeni, they will be stored in heterogeneous and distributed databases. Therefore, it is necessary to provkle a unified tnanagement for CE tool intcgration. Information Resource Dictionary System (IRDS) supports three-schema architecture in more generalized sense, and it is an efficient tool for integrating various CE information repositories. This paper introduces an IRDS system, its development, the concepts related, three-schema architecture, and application in CE information management.
