摘　　要：依据工程设计全过程中产品的各种配置项演变规律和控制方式的不同，提出了设计版本、在线版本、产品版本和发行版本的分类方法，分析了产品版本管理的数据模型应该满足的条件，提出了产品版本的版本追踪及其配置项信息的查询模型．After analyzing the different evolving disciplinarian of product data in designing a singleconfiguration item, developing and evolving a product, versions in engineering design are divided intodesign, online, product and distribution version. The management of the product versions is studiedfocusing on their storage. The main purpose of the management is to track the evolution of productversions, query the structure of a specified product version and the detailed information onconfiguration items. A data model of product version here has two levels: a directed acycline graph and a tree.Each tree is linked to a node in the directed acycline graph. From the trees, designers can browse thestructure of a specified product version visually and query the detailed information on configurationitems easily.
