    • A belt buckle assembly, especially for a seat belt system in a motor vehicle, includes a belt buckle (10) and a plug-in tongue (12) lockable in the belt buckle (10) by means of a locking mechanism. A component of the locking mechanism of the belt buckle (10) interacting with the plug-in tongue (12) inside the belt buckle (10) and/or the plug-in tongue (12) has/have design features at a locking portion (16) interacting with the locking mechanism of the belt buckle (10) inside the belt buckle (10). The design features enable the plug-in tongue (12) to be locked in the belt buckle (10) only at one of at least two possible orientations of the plug-in tongue (12) in the belt buckle (10).
    • 一种特别用于机动车辆中的安全带系统的皮带扣组件包括带扣(10)和可通过锁定机构锁定在带扣(10)中的插入式舌头(12)。 与带扣(10)和/或插入式舌头(12)内的插入式舌头(12)相互作用的带扣(10)的锁定机构的部件在锁定部分具有设计特征 (16)与带扣(10)内部的带扣(10)的锁定机构相互作用。 该设计特征使得插入式舌头(12)只能在皮带扣(10)中的插入式舌头(12)的至少两个可能取向中的任一个中被锁定在带扣(10)中。

    • A system and method for incrementally maintaining column cardinality estimates in database management systems. In one embodiment, the system includes system catalog table containing a cardinality estimate for a column that is extended to include an appropriate data structure. A modified linear counting technique is used in a first embodiment of a method for column cardinality estimation. The cardinality estimate is produced by an initial scan of the data but is then further maintained without requiring a full scan of the data. Data changes are reflected incrementally in modifications to the initial cardinality estimate, keeping the cardinality statistics more current with respect to the database condition. The technique of the invention typically provides a capability for a database management system to produce more efficient search plans providing more effective responses to user queries through the use of improved cardinality statistics.
    • 一种用于在数据库管理系统中逐行维护列基数估计的系统和方法。 在一个实施例中,系统包括系统目录表,其包含扩展为包括适当的数据结构的列的基数估计。 在列基数估计方法的第一实施例中使用经修改的线性计数技术。 基数估计是通过数据的初始扫描产生的,然后进一步维持,而不需要对数据进行全面扫描。 在初始基数估计的修改中,数据变化逐渐反映出来,保持基数统计信息相对于数据库条件更新。 本发明的技术通常提供了一种数据库管理系统产生更有效的搜索计划的能力,通过使用改进的基数统计来提供对用户查询的更有效的响应。
