新型高速公路养护信息数据平台的研究与开发

由于养护数据在位置,时间和类型上的复杂性,从而决定了关系型的二维表格并不是道路养护相关数据的最佳存储方式,且直接应用关系数据库作为数据平台将不利于形成良好的系统结构.文章给出的是一种基于XML的养护信息数据平台,该平台作为数据容器可以对养护相关的大量不确定关系数据进行有效的存储,并提供安全、便捷、高效的访问手段和二次开发接口;作为信息系统的软件总线,平台提供了基础的数据服务和事务服务,在简化系统结构的同时,提高了系统的开发效率.

Development of a New Platform for Freeway Pavement Maintenance Management Information Data

Such complexity of pavement maintenance data as location, time, and types of the maintenance data determines that the relational two-dimensional tables are not the best methods for storing highway maintenance related data. Meanwhile, the direct application of relational database as the data platform is unfavorable to the formation of a good system structure. In this paper, an XML-based maintenance information data platform was presented as a data container to effectively store large quantities of maintenance related data under uncertainties. Besides, this platform could provide a safe, convenient, and efficient means to access the maintenance data and software interface for later development. Moreover, as the data bus for information system, this platform provides basic data services and incident services, which simplifies the system structure and at the.same time greatly improves,the development efficiency of the system.
