1. A history management apparatus comprising:
a computer processor with associated memory storing instructions configuring the computer processor to,
display information of an inventory on a terminal,
receive, from the terminal, a quantity of a management target of the inventory at a first date,
write a first information record associating the quantity of a management target with a unique group ID and a second information record having a number of entries equal to the quantity of the management target, wherein each entry is assigned a unique sequence ID, the first date, and a first flag that indicates an existence of the management target, all in association with the unique group ID,
receive, from the terminal, a decrease in quantity of the management target of the inventory at a second date,
write, in response to the decrease in quantity of the management target, an additional entry in the first information record associating the decrease in quantity of the management target with a new group ID and the second date,
write, in a number of entries in the second information record equal to the decrease in quantity of the management target, the second date, the second flag, and the new group ID in association with the unique sequence ID of each of the entries, wherein the second flag overwrites the first flag in each of the entries and indicates an absence of the management target, and
display, in a graphical user interface on the terminal, the unique sequence ID, the unique group ID, and the first date in association with each other from all and only entries of the second information record having the first flag on the terminal so that all users of the apparatus are able, in real-time, to determine the inventory does not match the second information record and determine a date when the non-matching occurred.
