摘要： The present invention extends to methods, systems, and computer program products for mirroring file data. Generally, high availability and disaster recovery (“HADRON”) is achieved within a database management system by detecting which parts of a file have changed and sending the changed parts to secondaries. Adjacent or partially overlapping parts of a file can coalesce to form larger chunks of changed data. Coalescing reduces the overall number of chunks that are tracked.
摘要翻译：本发明扩展到用于镜像文件数据的方法，系统和计算机程序产品。通常，通过检测文件的哪些部分已更改并将更改后的部分发送给次要数据库管理系统，可实现高可用性和灾难恢复（“HADRON”）。文件的相邻或部分重叠的部分可以合并以形成更大的更改数据块。合并减少了跟踪的块的总数。

摘要： A method for mirroring one or more data changes from a first database server to one or more second database servers. The method includes intercepting one or more operations that make one or more changes to one or more data on the first database server. After intercepting these operations, the method merges the operations into one or more chunks, adds one or more log records having the chunks into a database log. The database log includes one or more database log blocks. The method then writes the database log blocks.

摘要： A database management system having a database component, which includes a lock manager, and a filesystem component. The filesystem component is configured to: generate a mapping between one or more filesystem access modes, one or more filesystem sharing modes and one or more database locks, receive a request from a filesystem stack to perform one or more actions on data in a database, identify a filesystem access mode and a filesystem share mode of the request, determine which one of the database locks corresponds to the filesystem access mode and the filesystem share mode of the request based on the mapping, and receive a notification lock on the data from the lock manager when no other database locks conflict with the notification lock, wherein the notification lock corresponds to the one of the database locks. After receiving the notification lock on the data, the lock manager is configured to send a notification to the filesystem component when a subsequent request from a database stack includes accessing the data.

摘要： Systems and methods that group atomic scalar values recognized by a database such as columns into sets (e.g., column sets). A grouping component associated with the SQL server creates a logical representation for column groupings, which are accessible by a single I/O and can be co-located (e.g., substantially close or compact) in terms of storage location. Interesting column sets (e.g., non-null) can also be selected for a data representation thereof as a single entity to other applications.

摘要： A method is provided for “but reasoning” with an inconsistent knowledge base. The method not only gives an answer to a Boolean question but also additional and instructive information. The method first finds a bridge statement that explains a contradiction between the answer and the inconsistent knowledge base. The method then selects a but statement that causes the contradiction with the answer, and constructs and validates a but answer with the answer, the but statement, and optionally the bridge statement.

摘要： A method for managing a binary object in a database system is provided. The method may include receiving a request to store the binary object and determining if a size of the binary object is above a first threshold. If the size is less than the first threshold, the method may include storing the binary object in a database of the database system using a database communication protocol. If the size is above the first threshold, the method may include determining if the size is above a second threshold. To this end, if the size is less than the second threshold, the method may include storing the binary object in a file system of the database system using the database communication protocol. Furthermore, if the size is above the second threshold, the method may include storing the binary object in the file system using a file system communication protocol.
