This is the most common and full featured way to use Omnata
Salesforce Connect Adapter
Omnata Connect is a custom adapter for Salesforce Connect which allows tables and views from a Snowflake account to be accessed as External Objects.
Whenever an External Object is accessed, the adapter creates a SQL query, executes the query in your data platform via a REST API call, and translates the result back into native Salesforce data types.
External Objects virtualise queried data on-platform without replicating it.
Using External Objects
External Objects behave very similarly to Standard and Custom Objects, but do not offer identical functionality for some platform features.
