This topic describes the application development in a typical scenario, helping you quickly learn and master the OpenTSDB development process and know key functions.

Scenario Description

Assume that a user develops an application to record and query the weather information of a city. Table 1, Table 2, and Table 3 describe the recorded data.

**Table 1** Raw data

In this scenario, the temperature and humidity data of the Longgang district, Shenzhen, is recorded at 00:00 on July 1, 2017. OpenTSDB uses two groups of data points for modeling.

Each group of metric data points has two tags:

Tags: City and District
Tag values: ShenZhen and Longgang

You can perform the following operations on data:

Obtain the daily monitored data and write data points of the two groups to the database through the put API of OpenTSDB.
Use the query API of OpenTSDB to query and analyze the existing data.
