简介:CDPD的全称为CELLULARDIGITALPACKETDATA,翻译成中文即“蜂窝数字分组数据通信”。它是以数字分组数据技术为基础,以蜂窝移动通信为组网方式的移动无线数据通信技术。CDPD是90年代初诞生于美国的新一代移动无线分组数据通信系统。
简介:简介由于拼写错误、意外的缩略语和其他不规则问题,实际的数据是“有问题”的。因此,在数据仓储项目中,很大一部分的时间和金钱都花费在了数据提取、数据转换和数据加载(ETL,Extraction、Transformation、Loading)阶段。在ETL阶段,新数据被清理、标准化,并使其与现有数据一致。在MicrosoftSQLServer2005中可用的模糊查找和模糊分组转换,有助于使ETL过程在遇到若干种在交际数据中观测到的常见错误时更易复原。它们解决一般的匹配和分组问题,而无需特定于域的规则和脚本的专家集合。通过为您的域自定义模糊查找和模糊分组,您可以利用BusinessIntelligenceDevelopmentStudio内的通用数据清理算法,并避免创建复杂的自定义规则和代码。
