勘测设计一体化软件开发过程中数据库的设计

DATABASE DESIGN IN SOFTWARE DEVELOPING PROCESS FOR INTEGRETION OF SURVEY AND DESIGN

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 experiences on developing the software in the integration of railway survey and design,through the analyses of the process of railway survey and design,the flow of data and the study on engineering database,this paper proposes the design method of the engineering database system for the integration of the survey and design.The functionlity,structure,data model and record's data fields,as well as its identification of the survey and design engineering database,are expounded also in this paper.
