Snowflake is a data platform that enables various types of data warehouses, including enterprise data warehouses, operational data stores, and team-specific data marts. These data warehouses can be used to provide business intelligence, metric reporting, and team-specific insights, depending on the specific needs of an organization. Snowflake's central data repository allows users to build these types of data warehouses by allocating computational resources for virtual computing clusters. The platform is versatile and can handle various use cases, including real-time streaming analytics and complex data apps, with its high-performance SQL query engine and cost-effective options such as Propel Data Cloud's GraphQL API.
