Industry Foundation Classes(IFC) defines the standard exchange data format of building information model. For making it possible to serve the whole life cycle of structure, it is necessary to parse and save BIM information based on IFC Standard into database. The research is implemented by Java language and MySQL database. The whole project is called IFCParser and consists of three modules: IFC Entity Module, IFCFile Parser Module and Persistence Module. IFCFile Parser Module uses lexical analyzer and syntax analyzer to decompose IFC files based on EXPRESS language into entity classes, which is called the IFC entity. Persistence Module establishes the mapping relationship between Java class and MySQL database, and uses MyBatis framework to save information into relational database.
