摘要:IFC作为BIM技术的核心概念,是为了提高建筑工程项目中各方的协作能力所制定的通用数据交换标准。为了解决传统的基于对象关系型数据库IFC数据存储的定义复杂和低效的问题,本文基于对象型层次型数据库,提出了一种通过IFC XML格式进行数据交换的新型IFC数据存储模型,介绍了IFC模式映射和数据库设计过程中的多种技术难点和解决方案并进行了实验验证。本研究对有效管理和利用IFC数据具有一定参考价值。
Abstract: 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.
