A data registration apparatus sets first data compression and second data compression, acquires the limit of the data amount of data to be registered in a database, and inputs data to be registered in the database. The data registration apparatus performs the first data compression and the second data compression for the inputted data. When the data amount of data compressed on the basis of the first data compression exceeds the acquired limit, the data registration apparatus registers data compressed on the basis of the second data compression in the database.
