MBD技术在制造业上的应用，使现有PDM系统中存在着大量RDB难以处理的非结构化数据。提出了一种PDM混合数据存储策略，用RDB存储零件的描述信息，而其实际内容则用No-SQL数据库存储。该方案不仅可以利用RDB的结构化特点来方便查询与统计，还能充分利用No-SQL灵活的存储结构较快处理非结构化数据。实验结果表明，该策略可以有效的提升查询速度，降低数据的存储空间。

With the application of MBD in the manufacturing industry,a large number of unstructured da-taisstoredinthePDMsystemwhichis hard to process by RDB. A hybrid storage strategy is proposed with RDB to store description information of parts and NoSQL to store non-geometric-information. It uses the structural characteristics of RDB to facilitate the query and statistics,and fully usesthestorage structures of NoSQL to process unstructured data quickly. The experimental results show that this strategy can effectively improve the query speed and reduce the data storage space.
