And now the application of data visualization is also very much, the actual application also shows the corresponding value.Say the above three points, and then say big data technology.The first thing to mention is Hadoop, a distributed storage that is now in use in most enterprises, while its distributed storage shortens the user's read time.

SSD interface is diverse, the mainstream SATA3.0 interface most common, the recent very hot M.2/PCI-E interface, once extremely the SSD most loves to use the mSATA interface, now has appeared a u.2 interface, must pedal m.2, replaces Sata, becomes the future SSD mainstream choice? What exactly is the U.2 interface? Today's SSD story, we'll talk about u.2 SSD. 　　What is the U.2 interface? The U.2 interface, formerly called SFF-8639, is driven by Intel single-handedly.

Just add one after "+"? "Just fine." Import re key = r "chuxiuhong@hit.edu.cn" p1 = r "@.+?\." #我想匹配到 @ back to "."

By plotting the frequency distribution histogram of the data, the normality of data

faster data rate (10MHZ) and a wider bus (bits). Called Fast/wide, SCSI-2 allowed data transfer rates up to MB/s with backward compatibility and SCSI-1, albeit at the SCSI-1 data rate. The development of SCSI-3 began in 1993 and is actually a collection of standards defining, protocols, command sets, and Si Gnaling methods. Under the moniker SCSI-3, you'll find a collection of parallel SCSI standards with the name Ultra and modern serial ased protocols such as the IEEE 1394 (FireWire), Fibre C
