IFC数据在关系数据库上的实现研究与应用

摘要

Building information modelling ( BIM) technology exchanges data through industry foundation classes ( IFC) standard, and further realises the information sharing between different information systems used in engineering projects.Based on analysing the concept correspondence between the IFC standard and the relational data model, we define the rule of transformation from IFC data model to relational data model, which provides the foundation for the implementation of BIM technology in relational database.The algorithm elaborately considers the influence of heritage relation and clustering relation on the design of rational database schema.At last, the effectiveness of the method is verified through the design process of transformation from IFC data model to relational data model in a bridge healthy management information system.%建筑信息模型（ BIM）技术通过工业基础类（ IFC）标准进行数据交换进而实现工程项目中使用的不同信息系统之间的信息共享。在分析IFC标准和关系数据模型之间概念对应的基础上，定义从IFC数据模型向关系数据模型的转换规则，为BIM在关系数据库上的实现提供基础。算法着重考虑了继承关系以及聚类关系对关系数据库模式设计的影响。最后通过桥梁健康管理信息系统中从IFC数据模型到关系数据模型的设计过程验证了该方法的有效性。
