摘要： Embodiments of the present invention provide fine grain concurrency control for transactions in the presence of database updates. During operations, each transaction is assigned a snapshot version number or SVN. A SVN refers to a historical snapshot of the database that can be created periodically or on demand. Transactions are thus tied to a particular SVN, such as, when the transaction was created. Queries belonging to the transactions can access data that is consistent as of a point in time, for example, corresponding to the latest SVN when the transaction was created. At various times, data from the database stored in a memory can be updated using the snapshot data corresponding to a SVN. When a transaction is committed, a snapshot of the database with a new SVN is created based on the data modified by the transaction and the snapshot is synchronized to the memory. When a transaction query requires data from a version of the database corresponding to a SVN, the data in the memory may be synchronized with the snapshot data corresponding to that SVN.

摘要翻译： 在存在数据库更新的情况下，本发明的实施例为事务提供细粒度并行性控制。 在操作期间，为每个事务分配一个快照版本号或SVN。 SVN是指可以定期或按需创建的数据库的历史快照。 因此，事务与特定的SVN相关联，例如，当事务被创建时。 属于事务的查询可以访问一个时间点一致的数据，例如对应于创建事务时的最新SVN。 在不同时间，可以使用对应于SVN的快照数据来更新存储在存储器中的数据库的数据。 提交事务时，将根据事务修改的数据创建具有新SVN的数据库快照，并将快照与内存同步。 当事务查询需要来自与SVN对应的数据库的版本的数据时，存储器中的数据可以与对应于该SVN的快照数据同步。

摘要： Embodiments of the present invention provide a run-time scheduler that schedules tasks for database queries on one or more execution resources in a dataflow fashion. In some embodiments, the run-time scheduler may comprise a task manager, a memory manager, and hardware resource manager. When a query is received by a host database management system, a query plan is created for that query. The query plan splits a query into various fragments. These fragments are further compiled into a directed acyclic graph of tasks. Unlike conventional scheduling, the dependency arc in the directed acyclic graph is based on page resources. Tasks may comprise machine code that may be executed by hardware to perform portions of the query. These tasks may also be performed in software or relate to I/O.

摘要： A file that has a holding portion configured for holding at least one stack of paper at a holding location. A first panel covers the holding location, and a second panel includes a traction surface and is rotatably associated with the first panel for movement between closed and open positions. In the closed position, the second panel is disposed against another portion of the file and in the open position, the second panel extends at an angle from the holding location for resting on a desktop. A traction surface has sufficiently high traction for supporting the holding portion and its held stack hanging therefrom while preventing the second panel from sliding off the desktop.

摘要： A system (e.g., a power supply) is presented which allows a user to electrically couple a common ground electrical potential of a circuit (e.g., a power supply circuit return) to, or electrically isolate the common ground electrical potential from, an earth grounded chassis, without having to open the chassis. The system may include a metal bolt and nut, wherein the nut is coupled to an electrically conductive bracket. The bracket is mounted upon a printed circuit board and electrically coupled to the common ground electrical potential. When an insulating bushing is installed in a hole in the chassis adjacent to the bracket, and a threaded shaft of the bolt extends through aligned holes in the insulating bushing, an insulating member positioned between the bracket and the chassis, and the bracket, and the threaded shaft engages the nut, the bolt holds the insulating bushing in place, and the bracket is electrically isolated from the chassis. When the insulating bushing is replaced with a conductive washer, the bolt and the conductive washer form a conductive electrical path between the bracket and the chassis. Components of the described system may be employed in systems having multiple cabinets (or complex cabinet systems) to achieve a single point of grounding. System components may also be employed to selectively isolate or couple a power supply return to a chassis ground in devices other than power supplies.
