Data classification storage system and method based on big data

Abstract

The invention discloses a data classified storage system and method based on big data, the data storage system comprises a database, a pre-judgment module, an inspection address division module, a first address analysis module and a second address analysis module, the database comprises a common database, a temporary database and a dustbin in sequence from high to low according to levels, the storage duration of the files in the common database is not limited, the storage duration of the files in the temporary database is a first storage duration, the storage duration of the files in the dustbin is a second storage duration, the first storage duration is greater than the second storage duration, and the pre-judgment module is used for setting a batch of files as to-be-classified files when the batch of files are received within a preset time period, obtaining the sending address of each to-be-classified file, and judging whether the sending address of a certain to-be-classified file is the sending address in a blacklist or not.

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...

Problems solved by technology

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
