Abstract

Disclosed is a data access device provided with a sequence storage unit which stores in advance a sequence for accessing the data contained in each of the multiple data units stored in a data storage section. The data access device receives and stores in the data access request storage section multiple data access requests for any of the multiple stored data units, determines an execution sequence for the multiple stored data access requests that corresponds to the aforementioned sequence stored in the sequence storage unit, locks the data units to be accessed as per the data access requests, sequentially implements the data access requests in the determined execution sequence, and removes all the locks after implementing all of the stored data access requests.
