摘要： An apparatus browses a list of data items. The apparatus includes a plurality of browse mechanisms each operable to scan concurrently through a list of data items and a plurality of independent groups each comprising two or more of the plurality of browse mechanisms. The browse mechanisms in a group cooperate together to browse the list of data items such that a data item is seen by only one member of the group.

摘要： The invention relates to the recovery of data in a database of database records, following a failure of a media containing said database. The data recovery uses a backup of the database and a log of log records detailing any changes in the database which are not captured in the backup. The log is replayed starting with the most recent log record. It is the determined for each successive log record, that relates to an operation on a database record, whether processing the log record will result in the most recent state of the corresponding database record, and if so, the log record is processed. Subsequently additional data is restored from the backup.
