description The invention provides a database establishing and retrieving method and device. The database establishing method comprises the steps that a data feature table is established, the data feature table comprises a first data information table, the first data information table is used for storing multiple different types of data information, and the data information comprises data storage paths; obtaining a storage path of data in the original data file; obtaining a storage position of the data in the data feature table according to the storage path of the data; inserting the data into the data feature table according to the storage position; and constructing a data feature database according to the data feature table into which the data is inserted. By implementing the data file retrieval method and device, the data file can be directly obtained directly for certain specific to-be-detected information or specific conditions, and the high efficiency and flexibility of data file retrieval are improved. 本发明提供了一种数据库
