The invention discloses a data processing method and device and belongs to the field of databases. The method comprises: determining a to-be-processed data line in a data table; educing the to-be-processed data line in n batches; deleting the data line which is educed in each batch from the data table; or, deleting the data line from the data table after the data line is archived to another data table. According to the data processing method and device disclosed by the invention, the educed data line is deleted by virtue of multi-batch data educing operation and less data educing operation of each batch, so that the problem in the correlated technology that the usability of the database is affected by relatively long data deleting time is solved; and when the large-scale data is deleted or archived, the data table is not locked on a large scale, the pressure on the data table in unit time is relatively small and the performance of the data table is not affected, so that the effect of the usability of the data table is improved.

The invention discloses a distributed file system data importing method and a distributed file system data importing device. The method comprises the following steps that: data contents are stored onto a storage node or a storage medium capable of being accessed by a source file system and a target file system; a data organization mode is determined according to a storage format of the target file system; an index node and a metadata organization structure of metadata in the target file system are built according to a metadata organization structure of the source file system and / or requirements of users; the storage information of the metadata in the target file system is regulated according to the data metadata mode, so the storage information of the metadata correctly points to the data contents stored on the storage node or the storage medium; and the corresponding data contents are read from the storage node or the storage medium according to the metadata in the target file system.

The invention discloses a data hiding method based on a Lagrange interpolation method and multiple clouds, which is applied in a system under a multi-cloud environment. The system comprises four parts: a user, a client, a data uploading layer, a data downloading layer and the clouds; before data are uploaded, an information segmentation algorithm of Reed Solomon erasure codes is used for segmenting the user data on the client, the Lagrange interpolation method is then used for carrying out information hiding on each block of segmented data, and finally, each block of data is stored in a different cloud storage. During data downloading, the data only need to be obtained from part of the cloud storages, the Lagrange interpolation method is first used for carrying out hidden information recovery on each block of data, and a recovery algorithm in Reed Solomon is then used for merging the data blocks to recover the original data. The data hiding method based on the Lagrange interpolation method and the multiple clouds solves the availability problem of services and the limitation of a single cloud storage; while reducing storage spaces, the usage of the Reed Solomon algorithm can tolerate the errors of the cloud storages; the usage of the Lagrange interpolation method solves the confidentiality problem of data, protecting the privacy of user data.
