What is a benefit of having primary and foreign keys in a Snowflake database?

They slow down data ingestion
They assist in schema navigation and relationships
They eliminate the need for joins
They guarantee data integrity

The correct answer is: They assist in schema navigation and relationships

Having primary and foreign keys in a Snowflake database provides significant advantages in understanding the relationships between different tables within the schema. When primary keys are defined, they identify unique records in a table, while foreign keys establish a link to those records from another table. This enables users to navigate the schema more effectively, making it easier to understand how different entities are connected and how data can be queried across multiple tables. This feature enhances the overall organization of the database and simplifies complex queries. While it's true that primary and foreign keys are important for enforcing data integrity and helping to guarantee consistency within the database, their primary role in this context is to assist with schema navigation and elucidate relationships between tables. This promotes better modeling of real-world scenarios in the data structure and facilitates data management and reporting tasks.
