+# Sample Data
+
+This chapter mainly introduces a simple temporal data application scenario and the modeling and example data in this scenario. All the example SQL statements in the IoTDB table model user manual can be executed under this modeling and example data.
+
+## Data Structure
+
+
+Table 1 and Table 2 both have the following table structure:

+
+## Import Statement
+
+The following is the SQL statement used to construct the above table structure and data. You can click here（[sample_data.sql](https://alioss.timecho.com/upload/sample_data.sql)）to download all the SQL statements and execute them in CLI to import the data into your IoTDB.

+-- Create a table with table names that are close to business semantics. Here, we use table1 instead
+-- The time column does not need to be manually specified, IoTDB will automatically create it
+-- The unit of TTL is ms, so 1 year is 31536000000 ms
