摘要
在 CAD/CAM 系统中,对于一个工程实体的设计,由于性能描述方法的不同,设计方案的差异,以及对性能要求的差别,在设计的各个阶段将会形成同一工程实体的不同设计版本。采用一般的商用数据库系统来管理这些不同的设计版本。
In this paper,a method which is called the“Forward version Management”is proposed by the author to hold the multiversion in an engineering database.This method can also generate some new database version in terms of the existing historic versioning data stored in an engineering database.Since several design versions can be stored simultaneously in a database,it is possible to hold the historic data and to support the backtracking in a design process.Therefore,it can meet the needs of“trial and error”procedure in designs.
