snowflake vs relational database

Similar to shared-disk architectures, Snowflake uses a central data repository for persisted data that is accessible from all compute nodes in the platform. Snowflake is a proper relational data warehouse platform and supports transactions, different isolation levels, ACID, read consistency and multi version concurrency control (MVCC). The snowflake schema is represented by centralized fact tables which are connected to multiple dimensions. .
