In production, raw data is typically ingested from platforms like Segment, Stitch, Fivetran, or another ETL/ELT tool. In this tutorial, we use dbt's seed functionality to create tables from CSV files. The CSV files are located in the ./data directory. Each CSV file produces one table, and dbt infers the column data types from the file contents.
