为促进交通运输行业数据的共享交换，加强共享交换信息的可理解性和信息系统的可维护性，结合交通运输行业信息化发展现状，提出统一交通运输信息系统数据库字段命名方法以及属性定义。在字段命名方面，考虑字段名的业务属性、标准性及可理解性，给出了包括基本业务领域标识、引用标准类别标识和字段名缩写等部分的字段命名规则，其中字段名缩写采用中文名称拼音缩写和英文名称缩写两种方法。在属性定义方面，根据《交通信息基础数据元》（JT/T 697—2013）中的数据属性定义方法，对常见的5类数据库管理系统的字段类型、格式及备注等属性定义作了推荐。相关交通运输信息化项目应用表明，通过对字段名和属性定义的规范，保证了数据交换和共享双方的相互识别，提高了在标准符合性检测方面的准确率。%In order to promote the quality of data sharing and exchanging in traffic&transportation in⁃dustry, and to enhance the comprehensibility of information and maintainability of information system, the method which unified field naming and attribute definition of database was developed, combining with the current situation of traffic&transportation informatization. In field naming, considering the ser⁃vice attribute, standardization and comprehensibility of field name, the field naming rule was introduced, which consisted of the identifier of basic service field, the category identifier of quoted standard and the abbreviation of field name. The field name was abbreviated from Chinese name or English name. In attri⁃bute definition, some attributes such as the type, format and memo etc. of filed in 5 common database management systems were recommended, according to the definition method of data attribute in"Basic Data Element of Transportation Information". The application in projects of traffic&transportation infor⁃ matization indicated that it not only ensures mutual recognition in data sharing and exchanging, but also increases the accuracy of standard conformance test by using the developed method.
