# 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>
