Snowflake and DV have no interdependency whatsoever. Snowflake is just a database. Whether you use DV to model the data inside of it or dimensional modelling or "big wide tables" is completely up to you, there's nothing about it that requires or benefits DV in particular.

What is DV?

Count not knowing what it is, as a blessing. Run if you can.

It's a data modelling method for data warehouses, it can be used in Snowflake or on any other data management platform.
