Machine learning data management system and data management method

A data management system, comprising:

• a data analysis server that generates curated data from raw data of various kinds of data, learns the curated data, and generates a learned data model;
• a data storage including a first storage area that stores the learned data model, a second storage area that stores the curated data, and a third storage area that stores the raw data;
• and
• a storage management server that manages the data storage,
• wherein the data analysis server:
• manages first data configuration information for managing a correspondence of the learned data model, a raw data bucket that stores the raw data for generating the learned data model, and a curated data bucket that stores the curated data for generating the learned data model;
• manages second data configuration information for managing correspondences of the learned data model and the first storage area, the curated data bucket and the second storage area, and the raw data bucket and the third storage area;
• sends an instruction to acquire snapshots of the second storage area that stores the curated data for generating the learned data model and the third storage area that stores the raw data for generating the learned data model to the data storage via the storage management server when the learned data model is generated;
• receives storage configuration management information and snapshot management information from the storage management server, and generates third data configuration information for managing snapshot acquisition times of the first storage area, the second storage area, and the third storage area, and
• generates a data chronological relation on the basis of the first data configuration information, the second data configuration information, and the third data configuration information.

A data management method in a data management system including a data analysis server that generates curated data from raw data of various kinds of data, learns the curated data, and generates a learned data model, a data storage including a first storage area that stores the learned data model, a second storage area that stores the curated data, and a third storage area that stores the raw data, and a storage management server that manages the data storage, the data management method comprising:

• managing, by the data analysis server, a correspondence of the learned data model, a raw data bucket that stores the raw data for generating the learned data model, and a curated data bucket that stores the curated data for generating the learned data model as first data configuration information;
• managing, by the data analysis server, second data configuration information for managing correspondences of the learned data model and the first storage area, the curated data bucket and the second storage area, and the raw data bucket and the third storage area;
• sending, by the data analysis server, an instruction to acquire snapshots of the second storage area that stores the curated data for generating the learned data model and the third storage area that stores the raw data for generating the learned data model to the data storage via the storage management server when the learned data model is generated;
• receiving, by the data analysis server, storage configuration management information and snapshot management information from the storage management server, and generating third data configuration information for managing snapshot acquisition times of the first storage area, the second storage area, and the third storage area;
• and
• managing at least two of snapshots of the learned data model, the curated data bucket, and the raw data bucket acquired at the same time as a consistent snapshot group on the basis of the second data configuration information and the third data configuration information.
