# Create an Insights Model

Call #POST /reporting/datamodels to create a data model. The following is an example that creates a data model while referencing the previously created YAML file.

* Access *sample_datasets* database and create two tables: **nasdaq** and **www_access**.
* Create a relationship between the **symbol** column and the **host** column.


For the API endpoint, select the appropriate [endpoint for your region](https://api-docs.treasuredata.com/en/overview/aboutendpoints/#treasure-data-sites-and-baseurls).


```bash
curl -X POST --data-urlencode "yaml=$(cat datamodel.yml)" \
-H 'Authorization: TD1 xxxx/xxxxxxxxxxxxxx' \
https://${TD_API_ENDPOINT}/reporting/datamodels
```

The actual Insights model is created in the analytics platform; the prefix created uses the following format: dm_{your account id}_.__ For example,__ if your account id is 1, the Insights model name is *dm_1_sample_datamodel.*

Model names are case insensitive; the model name automatically converts to lower case. For example, **data_MODEL_one** and **data_model_ONE** create the same data model: **data_model_one**.

The Analytics platform does not support *unixtimestamp*. If you want to use *datetime* in a widget, convert *unixtimestamp* to text with the timestamp format before you create an Insights model and define the column as a type of *timestamp*.
