维度模型是数据仓库的核心。它经过精心设计和优化，可以为数据分析和商业智能(BI)，检索并汇总大量的相关数据。在数据仓库中，数据修改仅定期发生，并且是一次性开销，而读取是经常发生的。对于一个数据检索效率比数据处理效率重要得多的数据结构而言，非标准化的维度模型是一个不错的解决方案。   Y    O

香港马会挂正牌   D Hello- I have an unusual problem perhaps someone could shed some light on: I have a TR-4 in 29K serial range that functions normally except it will not go back into receive, until after approx 30 second delay, after the mic button is released or the function switch turned back to "SSB". This condition worsens (longer delay) the more you frequently you transmit. The sidetone disappears but T-R relay will not release. I have tried different known-good 6EV7 tubes, have replaced a lot of the coupling / bypass caps in T-R circuits, did resistance / voltage checks, adjusted the VOX / VOX delay controls, tried other tubes in T-R circuit, etc. to no avail. What is real curious about this is that while waiting for it to go back into receive and T-R relay is engaged, IF YOU PULL THE 6EV7 FROM ITS SOCKET THE T-R RELAY STILL DOES NOT RELEASE. I suspect the issue is with the lead that goes from T-R relay coil to pin #1 on 6EV7 (somehow allowing enough leakage to ground?) or could it be the T-R relay coil itself I made sure socket / pins and all are clean on 6EV7.

 铮? P由于Cube运算的中间结果是以SequenceFile的格式存储在HDFS上的，所以为了导入HBase，还需要进行第七步操作，将这些结果转换成HFile（HBase文件存储格式）。第八步通过使用HBase BulkLoad工具，将HFile导入HBase集群，这一步完成后，HTable就可以查询到数据。第九步更新Cube的数据，将此次构建的Segment的状态从“NEW”更新为“READY”，表示已经可供查询。最后一步，清理构建过程中生成的临时文件等垃圾，释放集群资源。   S

Radar is an electronic device that detects planes, ships, coastlines, landmarks, and even storm clouds. The name radar comes from the first letters of the words radio direction and ranging. As the human eye uses light waves to see, radar "sees" with radio waves. Without radar, planes could not land safely in bad weather and ships could not move safely in thick fog.    R    X
