A data classification storage system and method based on big data

Abstract

The invention discloses a data classification storage system and method based on big data. The data storage system includes a database, a pre-judgment module, an investigation address division module, a first address analysis module and a second address analysis module. The database is based on The levels include a common database, a temporary database and a trash can in order from high to low. The files in the common database have no limit to the storage duration, the storage duration of the files in the temporary database is the first storage duration, and the files in the trash can The storage duration of the file is the second storage duration, the first storage duration is longer than the second storage duration, and the pre-judgment module is used to set the batch of files as files to be classified when receiving a batch of files within a preset time period , to obtain the sending address of each file to be classified, and judge whether the sending address of a certain file to be classified is the sending address in the blacklist.

Description

technical field [0001] The invention relates to the technical field of data classified storage, in particular to a big data-based data classified storage system and method. Background technique [0002] As the progress of social informatization is accelerating, more and more enterprises conduct office work through information technology such as the Internet. Whether it is between internal departments of the enterprise or between the internal and external of the enterprise, a lot of administrative document data will be generated in the process of working through information technology. Some of these administrative document data are extremely important and need to be stored for a long time, and some are irrelevant. , even if it is not processed, it doesn’t matter. If these administrative file data are not classified, it will lead to improper preservation of the file data and easily lead to loss; in the prior art, these administrative file data are often classified and integrat...

Whether it is between internal departments of the enterprise or between the internal and external of the enterprise, a lot of administrative document data will be generated in the process of working through information technology. Some of these administrative document data are extremely important and need to be stored for a long time, and some are irrelevant. , even if it is not processed, it does not matter, if these administrative file data are not classified, it will lead to improper preservation of the file data, which will easily lead to loss; in the prior art, these administrative file data are often classified and integrated artificially, but This artificial classification method is less efficient
