The frequency of occurrences of an exclusion process is reduced so as to enhance the efficiency of handling accesses to a database. A system is provided for controlling accesses to a database. The system includes a database identifying section that identifies a database corresponding to an input of a first access command, an access judging section that judges whether a series of accesses to the identified database initiated by a second access command still continue, a frequency determining section that determines how often accesses to the identified database occur with reference to a history of accesses. The system further comprises an access control section that checks the accesses made by the first access command to the identified database when the series of accesses to the identified database initiated by the second access command still continue and the frequency of accesses to the identified database determined by the frequency determining section is higher than or equal to a predetermined value.
