# Create an Insights Model Dataset

When you create or add a dataset to an Insights model, consider the following:

* **Definition**. Define the definition to have the same schema defined in the YAML file that was used to create the Insights model (POST /reporting/datamodels).
* **Database/table names**. Specify the database and table names, and their column information including: “type(required, currently only “presto” is available)”, indexed (optional, default value: false).
* **Dataset name**. There are no restrictions on what you name the dataset. Treasure Data recommends that you use the same name as the database.
