This invention is a technique to appropriately manage and use data before and after updating in a directory server. A data processing method executed by the directory server comprises: receiving first request data containing at least a first attribute value and concerning registration of an attribute into a particular entry and storing the first request data into a request data storage; generating first attribute data containing at least the first attribute value and data concerning a valid period of the first attribute value, and storing the first attribute data into a first attribute table; and storing an address of the first attribute table in which the first attribute data is stored, into an attribute management table corresponding to the particular entry. According to this method, as for the attribute, the attribute value is associated with data concerning the valid period of the attribute value. Therefore, a user can know which of the attribute values is currently valid, the period for which a particular attribute value was valid, and other information.
