PURPOSE:To facilitate an access to data to be repeatedly utilized by totaling the frequency of accesses to respective data by a user in a prescribed period, selecting the data in which the access frequency is large, recording them to a table, thereafter, referring to the table, and executing the access to the data. CONSTITUTION:Each time the user executes the access to a node, a frequency table 16 is referred to, the total access frequency of said node until such a time is updated, and the total access frequency is totaled in the prescribed period. Next, the node in the frequency table 16 is sorted by the total access frequency, a threshold is provided to the number of nodes or the total access frequency, the node is selected in the order of the degree of the total access frequency, and such node information is written to a node table 13. When the user requests only the data (data to be always used), in which the access frequency is large, in the access thereafter, a node table 18 is referred to, and the node recorded is blousing-displayed. Thus, the blousing and access of the node to be repeatedly utilized can be easily executed.
