Exercise 7

Create View for Europe Big Three Emissions

Use the source table co2_emissions_and_temperatures_by_country to create a view for the emissions data of the three major European countries: France, Germany, and the United Kingdom.

To create the view europe_big_three_emissions with the desired columns in the carbon_emissions schema:

1. Open your dbt project and navigate to the appropriate schema directory (e.g., models/carbon_emissions).
2. Create a new file named europe_big_three_emissions.sql (or any desired name) in the schema directory.
3. In the europe_big_three_emissions.sql file, write the dbt model definition for the view.
4. Define the europe_big_three_emissions model using the view materialization type.
5. Perform the necessary data transformations to reshape the data to meet the requirements.
6. Select the following columns for the output view:
   • Year: Integer
   • France_TotalEmissions: Float
   • France_PerCapitaEmissions: Float
   • Germany_TotalEmissions: Float
   • Germany_PerCapitaEmissions: Float
   • UnitedKingdom_TotalEmissions: Float
   • UnitedKingdom_PerCapitaEmissions: Float

By following these instructions and executing the appropriate dbt commands, you will create the view europe_big_three_emissions in the carbon_emissions schema. The view will contain the emissions data for the three major European countries, with the specified columns as outlined above.
