Data access analysis using entropy rate

A computer-readable non-transitory recording medium having stored therein a data analyzing program that causes a computer to execute a process. The process includes acquiring a transition matrix of data access based on a data access record of the data access; calculating an entropy rate for each of transition counts by using the transition matrix; determining mutual relevance of the data access based on the entropy rate; and storing data related to the data access on a disk, allocation of the data on the disk being determined by the mutual relevance of the data access.
