A term used to identi - fy a named portion of a partitioned data set ( pds ) . sometimes member is also used as a synonym for a data set 一种术语,用来标识分区数据集中某个命名部分,有时也用作为数据集的同义词。
Views can also be used when you copy data to and from microsoft sql server 2005 to improve performance and to partition data 还可以在向microsoft sql server 2005复制数据和从其中复制数据时使用视图,以便提高性能并对数据进行分区。
Hash bailout occurs when a hashing operation reaches its maximum recursion level and shifts to an alternate plan to process the remaining partitioned data 当哈希操作达到其最大递归级数并转换到替换计划以处理剩余的分区数据时发生哈希释放。
When you partition data across multiple servers , queries accessing only a fraction of the data can run faster because there is less data to scan 跨多个服务器对数据进行分区时,只访问一部分数据的查询可以较快地运行,因为只需扫描较少的数据。
How can you partition data so some information remains private for instance , " person x distrusts person y " , while other information is published to the world 怎样才能分割数据以便对某些信息保密(例如, “某人x不信任某人y ” )而将其它信息公之于众?
Partitioning data logically according to geographic locations or business uses can also prevent users from updating the same data values , thus avoiding conflicts 根据地理位置或业务用途对数据进行逻辑分区,可防止用户更新相同的数据值,从而避免发生冲突。
A view that joins horizontally partitioned data from a set of member tables that exist on one server . the data appears as if it is in one table . local server 订阅服务器与发布服务器在连接到网络时进行同步,并交换自上次同步以来发布服务器和订阅服务器间发生变化的所有行。
The simulation results illustrate that our cluster method converges faster and partitions data more balancedly than the current equal clustering method does when data set is dense or sparse 仿真实验表明:当样本集为样本密集型或稀疏型时,与原算法相比,我们提出的算法收敛性能更好,划分效果也更佳。
The vq - based approach assumes a gaussian mixture distribution , which fits real - world image data reasonably well . after estimating this distribution through em method , this approach trains optimized vector quantizers to partition data space 该方法使用更适合真实图像库的高斯混合模型描述数据分布,并训练优化的矢量量化器划分数据空间。
4 ) we present a protocol to solve the open problem brought forward by vaidya , i . e , how to construct privacy preserving boolean association rule mining protocol in vertically partitioned data of multiple parties 针对vaidya等人提出的一个公开问题,即如何构造对多个数据库有效的隐私关联规则挖掘协议,本文给出了一个多方的保持隐私的异构型数据库布尔关联规则挖掘协议。
