Indeed. Dataform however only does the T (transformation) in ELT. Most businesses are centralising an exploding diversity of raw data in the data warehouse and Dataform helps them manage the data there.

One other main difference with a product like composable is that Dataform is built with software engineering best practices in mind. The transformations are written in code (SQL) rather than a GUI. It enables version control, reusable components for example and makes it easier to manage a large number of interdependent transformations.
