• select a first raw data group from a raw data storage;
• store a first copy data group corresponding to the first raw data group in a buffer storage;
• and
• delete the first raw data group from of the raw data storage when the first copy data group is stored in the buffer storage;
• a first loader configured to:
• receive the first copy data group from the buffer storage;
• store a first storage data group corresponding to the first copy data group in a database;
• and
• delete the first copy data group from of the buffer storage when the first storage data group is stored in the database;
• and
• a monitoring unit configured to:
• monitor the buffer storage;
• and
