As the core concept of BIM technology, IFC is a general data exchange standard developed to improve the collaborative capabilities of all parties in construction projects. In order to solve the complex definition and inefficiency of the traditional IFC data storage based on object-relational database, this paper proposes a new IFC data storage model for data exchange through IFC XML format based on the object hierarchical database and introduces various technical difficulties and solutions in the process of pattern mapping. The database design were verified by experiments. This research has certain reference value for the effective management and utilization of IFC data.
