1、与传统数据库中的名词作比较
| influxDB中的名词 | 传统数据库中的概念 |
| database | 数据库 |
| measurement | 数据库中的表 |
| points | 表里面的一行数据 |
2、InfluxDB中独有的概念
1）Point
Point由时间戳（time）、数据（field）、标签（tags）组成。数据库
Point至关于传统数据库里的一行数据，以下表所示：post
| Point属性 | 传统数据库中的概念 |
| time | 每一个数据记录时间，是数据库中的主索引(会自动生成) |
| fields | 各类记录值（没有索引的属性）也就是记录的值：温度， 湿度 |
| tags | 各类有索引的属性：地区，海拔 |
2）series
全部在数据库中的数据，都须要经过图表来展现，而这个series表示这个表里面的数据，能够在图表上画成几条线：经过tags排列组合算出来。spa
以下所示：code
>show series from cpu key cpu,cpu=cpu-total,host=ResourcePool-0246-billing07 cpu,cpu=cpu-total,host=billing07 cpu,cpu=cpu0,host=ResourcePool-0246-billing07 cpu,cpu=cpu0,host=billing07 cpu,cpu=cpu1,host=ResourcePool-0246-billing07 cpu,cpu=cpu1,host=billing07 cpu,cpu=cpu10,host=ResourcePool-0246-billing07 cpu,cpu=cpu10,host=billing07 cpu,cpu=cpu11,host=ResourcePool-0246-billing07 cpu,cpu=cpu11,host=billing07 cpu,cpu=cpu12,host=ResourcePool-0246-billing07 cpu,cpu=cpu12,host=billing07 cpu,cpu=cpu13,host=ResourcePool-0246-billing07 cpu,cpu=cpu13,host=billing07 cpu,cpu=cpu14,host=ResourcePool-0246-billing07 cpu,cpu=cpu14,host=billing07 cpu,cpu=cpu15,host=ResourcePool-0246-billing07 cpu,cpu=cpu15,host=billing07 cpu,cpu=cpu16,host=ResourcePool-0246-billing07 cpu,cpu=cpu17,host=ResourcePool-0246-billing07 cpu,cpu=cpu18,host=ResourcePool-0246-billing07 cpu,cpu=cpu19,host=ResourcePool-0246-billing07 cpu,cpu=cpu2,host=ResourcePool-0246-billing07 cpu,cpu=cpu2,host=billing07 cpu,cpu=cpu20,host=ResourcePool-0246-billing07 cpu,cpu=cpu21,host=ResourcePool-0246-billing07 cpu,cpu=cpu22,host=ResourcePool-0246-billing07 cpu,cpu=cpu23,host=ResourcePool-0246-billing07 cpu,cpu=cpu3,host=ResourcePool-0246-billing07 cpu,cpu=cpu3,host=billing07 cpu,cpu=cpu4,host=ResourcePool-0246-billing07 cpu,cpu=cpu4,host=billing07 cpu,cpu=cpu5,host=ResourcePool-0246-billing07 cpu,cpu=cpu5,host=billing07 cpu,cpu=cpu6,host=ResourcePool-0246-billing07 cpu,cpu=cpu6,host=billing07 cpu,cpu=cpu7,host=ResourcePool-0246-billing07 cpu,cpu=cpu7,host=billing07 cpu,cpu=cpu8,host=ResourcePool-0246-billing07 cpu,cpu=cpu8,host=billing07 cpu,cpu=cpu9,host=ResourcePool-0246-billing07 cpu,cpu=cpu9,host=billing07
