    摘要： A method and apparatus are disclosed for querying streaming extensible markup language (XML) data comprising: routing elements to query nodes, the elements derived from the streaming extensible markup language data; filtering out elements not conforming to one or more predetermined path query patterns; adding remaining elements to one or more dynamic element lists; accessing a decision table to select and return a query node related to a cursor element from the dynamic element lists; and processing the cursor element related to the returned query node to produce an extracted tuple output.

    摘要： A computer-implemented method for use with an extensible markup language (XML) document includes inputting a high-level mapping specification for a schema mapping; and generating a target XML document based on the mapping. The method may perform schema mapping-based XML transformation as a three-phase process comprising tuple extraction, XML-fragment generation, and data merging. The tuple extraction phase may be adapted to handle streamed XML data (as well as stored/indexed XML data). The data merging phase may use a hybrid method that can dynamically switch between main memory-based and disk-based algorithms based on the size of the XML data to be merged.

    摘要： A method for maintaining the status of a bootstrap peer includes: selecting a bootstrap peer; obtaining the status information of the bootstrap peer; updating a local bootstrap peer list according to the status information of the bootstrap peer. An apparatus and system for maintaining the status of a bootstrap peer are also disclosed. The bootstrap peer list is updated according to the status information of the selected bootstrap peer, which ensures the validity of the bootstrap peer list on the bootstrap server so that the information in the bootstrap peer list obtained by a joining peer is valid. This improves the success rate of joining the overlay network by the joining peer, shortens the joining process time of the joining peer, and implements load balancing between the bootstrap peers.

    摘要： A system of accessing a copy-prevented encrypted data file transmitted over a network includes a server apparatus having data files; and a client apparatus comprising a read apparatus and a temporary storage. A data file in a server apparatus is accessed through the network from the client apparatus and cached in the temporary storage, and the data file cached in the temporary storage is obtainable by the read apparatus for human recognition of the content of the data file. The read apparatus is not capable of at least one of printing and saving as. The present invention also provides a method of accessing a copy-prevented encrypted data file from a server apparatus. The system and method improve data file transmission security and decrease the possibility of copying and decrypting the data file.

    摘要： A device may store information associated with a group of items in a database. The information associated with a particular item may include a group of versions of a particular attribute. A particular version of the particular attribute may include a value associated with the particular attribute and a timestamp. The device may receive a query that specifies a time; determine that the query is associated with the particular item; and determine, based on the specified time, which version of the particular attribute is associated with the query. The device may determine which version of the particular attribute is associated with the query by identifying, based on the timestamps associated with the versions of the particular attribute, a version of the particular attribute that is a newest version, of the versions of the particular attribute that are associated with timestamps that are before or concurrent with the specified time.
