北斗导航公路物流信息系统的数据库设计

Database Design of Road Logistics Information System Based on Beidou Satellite Navigation

数据库在北斗卫星导航信息系统中占有举足轻重的地位,关系到系统的成败,需综合考虑多种因素进行设计。在研究卫星导航系统网络结构、系统功能和模块构成后,提出了系统数据库的设计思想,给出了比较详细的主要数据表结构,并分析了主要数据表之间的关联关系。

Database plays an important role in the road logis-tics information system based on beidou satellite navigation.＆amp;nbsp;The database should be considered comprehensively before designing because it concerns the success of this system. Af-ter researching the network structure of satellite navigation system, system function and modules, I proposed design ideas of system database, provided a relatively particular main data table structure and analyzed the incidence relations between main data tables.
