To initialize the data environment, open a github codespace:

Once started, execute the following commands in the terminal:

$ dbt deps
$ dbt seed
$ dbt build

to verify the data product:

$ dbt test

to inspect the underlying data yourself:

$ duckcli database.duckdb
> select * from active_users

what we get:
