    摘要: An information processing system, a data update method and a data update program are disclosed. In a data base system of master-slave configuration, the update result can be accessed also on slave side with the access request immediately after the particular update. The data base system DBS includes a master DB computer and at least a slave DB computer. The slave DB computer judges from the count on an update counter table whether the update log received from the master DB computer is to be reflected in a duplicate data base or not. Thus, the lost update problem is solved while at the same time realizing a high-speed process.

    摘要: Provided is a data management method. Data corresponds to an entry including a reference to another entry and is managed in a set which is a collection of pieces of the data. The set corresponds to a linked list where the entry corresponding to the data is linked in order of addition of the data. The entry includes an insertion time sequence number inserted into the linked list and information indicating if the data has been deleted from the set. In that case, the entry is separated from the linked list at a predetermined timing. The linked list is traced to refer to the data. When the insertion time sequence number of the reference entry is later than the insertion time sequence number of the entry which has already been referred to, it is judged that the reference entry has been separated from the linked list.
