# Data Model | ||
|
||
## Basic Concepts | ||
|
||
To manage industrial IoT timing data, the measurement point data model of TsFile includes the following information | ||
|
||
- DeviceId(String):Device Name | ||
- MeasurementSchema:Measurement points | ||
- measurementId(String):Measurement Point Name | ||
- tsDataType(TSDataType):Data Type | ||
|
||
For the above detailed introduction, please refer to:[Entering Time Series Data](https://tsfile.apache.org/UserGuide/latest/QuickStart/Navigating_Time_Series_Data.html) | ||
|
||
## Example | ||
|
||
![](https://alioss.timecho.com/docs/img/20240502164237-dkcm.png) | ||
|
||
In the above example, the metadata (Scheme) of TsFile contains 2 devices and 5 time series, and is established as a table structure as shown in the following figure: | ||
|
||
<table> | ||
<tr> | ||
<th rowspan="1">Device ID</th> | ||
<th rowspan="1">Measurement points</th> | ||
</tr> | ||
<tr> | ||
<th rowspan="2">Solar panel 1</th> | ||
<th>Voltage(FLOAT)</th> | ||
</tr> | ||
<tr> | ||
<th>Current(FLOAT)</th> | ||
</tr> | ||
<tr> | ||
<th rowspan="4">Fan1</th> | ||
</tr> | ||
<tr> | ||
<th>Voltage(FLOAT)</th> | ||
</tr> | ||
<tr> | ||
<th>Current(FLOAT)</th> | ||
</tr> | ||
<tr> | ||
<th>Wind Speed(FLOAT)</th> | ||
</tr> | ||
</table> | ||

# TsFile 数据模型 | ||
|
||
## 基本概念 | ||
|
||
为管理工业物联网时序数据,TsFile 的测点数据模型包含如下信息 | ||
|
||
- DeviceId(String):设备名 | ||
- MeasurementSchema:测点 | ||
- measurementId(String):测点名 | ||
- tsDataType(TSDataType):数据类型 | ||
|
||
有关上述详细介绍,参见:[走进时序数据](https://tsfile.apache.org/zh/UserGuide/latest/QuickStart/Navigating_Time_Series_Data.html) | ||
|
||
## 示例 | ||
|
||
![](https://alioss.timecho.com/docs/img/tsfile%E6%95%B0%E6%8D%AE%E6%A8%A1%E5%9E%8B.png) | ||
|
||
在上述示例中,TsFile 的元数据(Schema)共包含 2 个设备,5条时间序列,建立为表结构如下图: | ||
|
||
<table> | ||
<tr> | ||
<th rowspan="1">设备ID</th> | ||
<th rowspan="1">测点</th> | ||
</tr> | ||
<tr> | ||
<th rowspan="2">太阳能板1</th> | ||
<th>电压(FLOAT)</th> | ||
</tr> | ||
<tr> | ||
<th>电流(FLOAT)</th> | ||
</tr> | ||
<tr> | ||
<th rowspan="4">风机1</th> | ||
</tr> | ||
<tr> | ||
<th>电压(FLOAT)</th> | ||
</tr> | ||
<tr> | ||
<th>电流(FLOAT)</th> | ||
</tr> | ||
<tr> | ||
<th>风速(FLOAT)</th> | ||
</tr> | ||
</table> | ||
