A first loader receives the first copy data group from the buffer storage, stores a first storage data group corresponding to the first copy data group in a database, and deletes the first copy data group from the buffer storage when the first storage data group is stored in the database. A monitoring unit determines whether the first copy data group has been processed based on monitoring the buffer storage. ## Claims ### Claim 1 A data processing apparatus for diagnosing a battery state, the apparatus comprising: a first controller configured to: 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 determine, based on the monitoring of the buffer storage, whether the first copy data group has been processed. ### Claim 2 (depends on 1) The data processing apparatus of claim 1, wherein the monitoring unit is further configured to, when the first loader fails to store the first storage data group corresponding to the first copy data group in the database: receive the first copy data group from the buffer storage; store the first storage data group corresponding to the first copy data group in the database; and delete the first copy data group from of the buffer storage when the first storage data group is stored in the database. ### Claim 3 (depends on 1) The data processing apparatus of claim 1, further comprising a second controller configured to: select a second raw data group from the raw data storage; store a second copy data group corresponding to the selected second raw data group in the buffer storage; and delete the second raw data group from the raw data storage when the second copy data group is stored in the buffer storage. ### Claim 4 (depends on 3) The data processing apparatus of claim 3, further comprising a timing controller configured to execute the second controller when the first controller deletes the first raw data group of the raw data storage. ### Claim 5 (depends on 3) The data processing apparatus of claim 3, further comprising a second loader configured to: receive the second copy data group from the buffer storage; store a second storage data group corresponding to the second copy data group in the database; and delete the second copy data group from of the buffer storage when the second storage data group is stored in the database. ### Claim 6 (depends on 3) The data processing apparatus of claim 3, further comprising a timing controller configured to execute the second controller when the first controller fails to select the first raw data group. ### Claim 7 (depends on 6) The data processing apparatus of claim 6, wherein the second raw data group selected by the second controller comprises raw data that the first controller fails to select. ### Claim 8 (depends on 1) The data processing apparatus of claim 1, wherein the first controller is further configured to: match the first copy data group with first time information; and store the first copy data group and the first time information, wherein the first time information corresponds to a generation time of the first copy data group. ### Claim 9 (depends on 8) The data processing apparatus of claim 8, wherein the monitoring unit is further configured to compare the first time information with reference time information to determine whether the first copy data group has been processed. ### Claim 10 A method of diagnosing a battery state, the method comprising: selecting a first raw data group from a raw data storage; storing a first copy data group corresponding to the first raw data group in a buffer storage; deleting the first raw data group from the raw data storage when the first copy data group is stored in the buffer storage; storing a first storage data group corresponding to the first copy data group in a database; and deleting the first copy data group of the buffer storage when the first storage data group is stored in the database. ### Claim 11 (depends on 10) The method of claim 10, further comprising determining, based on monitoring the buffer storage, whether the first copy data group has been processed. ### Claim 12 (depends on 11) The method of claim 11, further comprising: matching the first copy data group with first time information; and storing the first copy data group and the first time information, wherein the first time information corresponds to a generation time of the first copy data group. ### Claim 13 (depends on 11) The method of claim 11, wherein determining whether the first copy data group has been processed comprises comparing the first time information with reference time information to determine whether the first copy data group has been processed. ### Claim 14 (depends on 11) The method of claim 11, further comprising, based on failing to store the first storage data group corresponding to the first copy data group in the database: determining that processing of the first copy data group is omitted; receiving the first copy data group from the buffer storage; storing the first storage data group corresponding to the first copy data group in the database; and deleting the first copy data group from the buffer storage. ### Claim 15 (depends on 10) The method of claim 10, further comprising: executing a second controller when a first controller deletes the first raw data group from the raw data storage; selecting a second raw data group from the raw data storage; storing a second copy data group corresponding to the selected second raw data group in the buffer storage; deleting the second raw data group of the raw data storage; receiving the second copy data group from the buffer storage; storing a second storage data group corresponding to the second copy data group in the database; and deleting the second copy data group from the buffer storage. ### Claim 16 (depends on 10) The method of claim 10, further comprising: executing a second controller, when a first controller fails to select the first raw data group; and selecting from the raw data storage, a second raw data group comprising raw data not selected for the first raw data group.
