Snowflake SnowPro Certification Practice Test

What is one of the best practices for data modeling in Snowflake?

1. Flat File Storage

2. Data Vault

3. Hierarchical Data Management

4. Document-Oriented Design

The correct answer is: Data Vault

Data Vault is considered one of the best practices for data modeling in Snowflake due to its ability to handle large volumes of rapidly changing data while maintaining an auditable history of changes. This approach is particularly beneficial in environments where data needs to be integrated from multiple sources, facilitating a robust and flexible model that allows for the easy addition of new data sources without disrupting existing structures. The Data Vault methodology emphasizes the separation of data into three core components: hubs (representing business entities), links (representing relationships between those entities), and satellites (storing the contextual information about the entities, including historical data). This structure supports scalability and adaptability, making it ideal for modern data warehousing environments where requirements might evolve over time. In contrast, flat file storage does not leverage the advanced capabilities of Snowflake for data integration and analysis, while hierarchical data management can limit the flexibility and scalability needed for extensive and complex queries. Document-oriented design finds its strength in NoSQL structures, which may not be the best fit for Snowflake’s relational database environment designed for structured data analytics.
