Method and system for establishing data index

The invention discloses a method and system for establishing a data index, and the method comprises the steps: obtaining target data which is the data of a to-be-established data index, obtaining a user-defined data model, and establishing the index of the target data based on the user-defined data model. The index can be automatically created according to the user-defined data model, and the storage can be optimized in the process of establishing the data index. 本发明公开了一种建立数据索引的方法及系统，方法包括：获取目标数据，目标数据为待建立数据索引的数据，获取用户自定义数据模型，基于用户自定义数据模型建立所述目标数据的索引。本发明能够根据用户自定义的数据模型自动创建索引，且在建立数据索引的过程中，能够对存储进行优化。
