Hi, I am trying to make my custom transform to calculate data aggregates from a table in postgres. I have completed the EL part but need to make my own transform, any resources on how I can create a custom transform? I looked up the above link and it gives a error 404.

Any place resources regarding this are available, I can't seem to figure out where everything goes in a dbt, specifically were exactly to write the business logic for a dbt in the meltano project directory structure

<https://meltano.com/docs/transforms.html>

the ./transform directory is a dbt project. Use it just as you would DBT
