摘要： A database view of a database is created which provides a transaction-consistent view of an existing database at a previous time. Each database view contains all the information needed to, along with the primary database, determine the contents of the primary database at a previous time. The database view consists of a side file corresponding to each data file in the primary database. The side files contain a copy of all data from the corresponding data file which has been changed since the database view was created. Sparse files may be used for the side files in order to conserve space. Page table data is kept in order to allow a quick determination as to whether the page from the primary database has been modified and the old version stored in the database view side file.

摘要： A system and method for synchronizing a database comprising raw data and metadata derived from the raw data, but when the metadata has not yet been updated. The raw data and the metadata are first synchronized, with the raw data having been assigned a version number. After synchronization, any stale metadata will be updated and assigned the same version number as the raw data.

摘要： A base table is scanned with a delete marker and an insert marker. The delete marker identifies a last change committed to the base table as part of a transaction prior to execution of a statement, and the insert marker identifies a last change committed to base table as part of the transaction during execution of the statement. The results of the delete marker scan are filtered with deletions stored in a delta table, and a delete table is populated with the filtered rows. The results of the insert scan are filtered with insertions stored in the delta table, and an insert table is populated with the filtered rows.

摘要： Various embodiments of the present invention are directed to systems and methods for synchronizing mixed elements (MEs) comprising structure data and unstructured filestreams between peer computer systems in a hardware/software interface system environment that does not permit snapshotting of large unstructured ME filestreams during synchronization. For several such embodiments, the method comprises synchronizing the ME in two steps, one for snapshotting the structured data component of the ME (as well as the cv of the filestream but not the filestream itself) and one for locking and transmitting the filestream to the receiving sync peer if and only if, after being locked, it is determined that the filestream is unchanged from the time of the ME data component snapshot.

摘要： The location of appropriate undo data necessary for reversing an effect of an operation performed at a computer system is identified during a forward pass through a log. A cycle count can be used to determine if appropriate undo data is stored in an object or is stored in auxiliary storage. If appropriate undo data is stored in an object and the undo data would be potentially lost by processing a redo log entry to modify the contents of the object, the appropriate undo data is copied to auxiliary storage. In some embodiments, a secondary computer system receives log entries from a primary computer system. The secondary computer system can identify undo data necessary to reverse an effect of an operation performed at the secondary computer system from received log entries. Identified undo data can be copied auxiliary storage at the secondary computer system.

摘要： A linked data structure verification system to verify the integrity of at least one linked data structure simultaneously by way of a verification setup phase and an integrity verification phase. Individual nodes are retrieved from a memory device and examined seriatim in optimal memory device location order. Nodes are retrieved and examined in optimal memory device location order for maximum memory device retrieval performance. Expected and/or actual node information about nodes in a given linked data structure are temporarily stored as records in an integrity verification table for only as much time as is necessary to verify any part of the node information prior to excising one or more unnecessary records from the integrity verification table.

摘要： An XML based type-definition language for declaring content-index for WinFS Types is provided. Content-index declarations can be specified for the Item type as well as it's sub-entities like Fragments, etc across Item type hierarchies. The properties of WinFS types in the schema are marked for content-indexing by the schema designer. Installing the content-index definitions includes parsing content-index definitions in the schema, generation of appropriate SQL statements for data extraction and storing the SQL statements.
