Tracing data storage method and system

The invention discloses a traceability data storage method and system. The method comprises the steps that an index tree corresponding to business data is constructed, the index tree comprises a plurality of index nodes, and the index nodes comprise metadata information corresponding to the business data; metadata information in the index tree is stored in a preset database; and tracing the business data in a preset database, and displaying a tracing result. According to the invention, the technical problem of low data tracing efficiency in a large-scale data scene in the prior art is solved. 本发明公开了一种溯源数据存储方法以及系统。其中，该方法包括：构建与业务数据对应的指标树，其中，指标树包括多个指标节点，指标节点中包括业务数据对应的元数据信息；将指标树中的元数据信息存储至预设数据库中；在预设数据库中对业务数据进行溯源，并展示溯源结果。本发明解决了相关技术中大规模数据场景下数据溯源效率低的技术问题。
