结合开发勘测设计一体化软件的实践经验和体会,通过分析铁路勘测设计的过程和数据库流程,提出了铁路勘测设计一体化工程数据库系统的设计方法,并对其功能、结构、数据模型以及实体的数据项和库中的标识等方面进行了阐述。

Based on the ex periences on develo ping the sof twa re in the integ ratio n o f railway surv ey a nd design, throug h the analy ses of the process of railw ay survey and desig n, the f low of da ta and the study o n engineering database, this paper proposes the desig n method of the engineering database system for the integ ratio n of the surv ey and desig n. The functionli ty , st ructure, da ta model and reco rd 's data fields, as w ell as i ts identificatio n of the surv ey and desig n engineering da taba se, are expounded also in thi s paper.
