    摘要: The use of disk-assisted, dynamic databases is to be optimized. To this end, provision is made for new data intended to update an old stock of data to have a second index, relating to the new data, generated for them, and for said second index to be stored on the disk storage medium as a supplement to the first index relating to the old stock of data. This allows the number of write access operations to the disk storage medium to be reduced. This is particularly advantageous for optical media, whose useful life can be increased as a result.

    摘要: Search in stocks of data, particularly on optical media, is intended to be optimized in terms of the time required for the search. It is therefore proposed that the search be carried out in two steps. In a first search step, the entire database is scanned on the disk storage medium. In a second search step, executed in parallel, intermediate results from the first search step are searched. This allows the number of skips on a disk to be reduced, which results in increases of speed, particularly in the case of optical drives.

    摘要: For the creation and self-organization of peer-groups the JXTA protocol may be used, which includes messages such as peer or peer-group advertisements and services such as the discovery service. Conventional peer-groups of this type are static and need restart after any modification, e.g. a new service. A method for dynamically managing hardware and/or software elements, e.g. services, utilized and/or offered by such peer-groups comprises detecting a change within a peer-group, creating a new peer-group identifier, publishing within the peer-group a first peer-group advertisement message that includes the current and the new peer-group identifier and pointers to current services including the detected modification, accepting the new peer-group identifier by the other peer-group members, and publishing a second peer-group advertisement message in the superordinate peer-group, wherein both advertisement messages may be identical. Thus, peer-groups may operate continuously while peers modify, add or delete services.

    摘要: The resistance against recording defects of a write-once optical disk is enhanced allowing realtime recording and playback of data streams with a single speed disk drive. A data stream is recorded in data blocks on the optical disk. An error correction block for one or more data blocks is generated and written on the same optical disk during recording. A spare data area is kept blank on the storage medium and used for storing a defect data block reconstructed by using the error correction block.
