摘要： In order to provide a more efficient persistent storage device, one or more long-term storage media are included along with a non-volatile memory. In one embodiment, one portion of the non-volatile memory is used as a write buffer and a read cache for writes and reads to the long-term storage media. Interfaces are provided for controlling the use of the non-volatile memory as a write buffer and a read cache. Additionally, a portion of the non-volatile memory is used to provide a direct mapping for specified sectors of the long-term storage media. Descriptive data regarding the persistent storage device is stored in another portion of the non-volatile memory.

摘要： In order to provide recovery for a database stored on storage not meeting the WAL protocol requirements, for example, storage including a temporary cache and a second storage (e.g. an IDE disk with a temporary cache and a hard disk), a log is created including, for each changed page, a pre-image of the page before changes were effected. The log also includes one or more change log records logging changes made to the page. Periodic checkpoints occur in which the cached pages are flushed to the disk. Recovery proceeds with a redo pass through the active log and then with an undo pass, undoing any transactions that have not been committed.

摘要： The present invention relates to a system and method of data restoration, for instance, after the occurrence of a user error. In particular, snapshot database can be maintained that stores a copy of database data. The snapshot database does not have to store a complete copy of all data on a source database, but rather shares data that is common to both but not necessarily identical. If an error occurs on the primary database then the database can be reverted back to a point in time prior to the error by replacing source database files with snapshot files. Additionally, an undo component can be employed in conjunction with the snapshot to approach an error to a finer grained point in time. In brief, the present invention can restore a database much faster and simpler, while utilizing less space and resources than conventional data restoration technologies.
摘要翻译：本发明涉及数据恢复的系统和方法，例如在用户错误发生之后。特别地，可以维护存储数据库数据的副本的快照数据库。快照数据库不必在源数据库上存储所有数据的完整副本，而是共享两者共同但不一定相同的数据。如果主数据库发生错误，则数据库可以通过将源数据库文件替换为快照文件来恢复到错误之前的时间点。另外，一个撤销组件可以与快照一起使用，以将错误接近一个更精细的粒度点。简而言之，本发明可以比传统的数据恢复技术更少和更少地使用更少的空间和资源来更快速和简单地恢复数据库。

摘要： Systems and methods that qualify and/or restrict access of codes associated with a database to objects located outside thereof and in other databases—even though a person executing such code does in fact have permission to interact with the object that the code is attempting to access. A sandbox component can regulate access from one database to another database, by managing authenticator permission and/or trust permission levels. Hence, the set of privileges assigned to security execution context of an executable module (procedure, trigger, computed column) in an un-trusted database is restricted not to exceed a privilege set assigned to database owner.

摘要： The subject disclosure relates to a concurrency control technique that ensures isolation among concurrently execution transactions optimistically in a multiversion database by applying two optional tests at the end of a read-write transaction: validating the visibility of the read set of the read-write transaction(s) and phantom detection by re-scanning and confirming no new version have appeared in the view. Depending on desired level of isolation, both, one or none of the test are applied. Each version of a data record in an applicable database can be assigned two timestamps indicating the lifetime the version. The value of a version timestamp, though assigned, may be conditional on a transaction committing.
摘要翻译：本公开涉及一种并发控制技术，其通过在读写事务结束时应用两个可选测试来确保在多版本数据库中乐观地同时执行事务之间的隔离：验证读写事务的读取集的可见性（ s）和幻影检测通过重新扫描和确认没有新版本出现在视图中。根据所需的隔离度，两者都应用一个或者没有一个测试。可以为适用的数据库中的每个版本的数据记录分配两个表示该版本的生命周期的时间戳。版本时间戳的值（尽管已分配）可能以事务提交为条件。
