Sample Questions and Answers

Q1: What is the purpose of the ref function in DBT?

A1: The ref function in DBT is used to reference another model within a DBT project. This function creates dependencies between models and ensures that they are run in the correct order.

Q2: How can you implement data tests in DBT?

A2: Data tests in DBT can be implemented using schema tests and custom tests. Schema tests are defined in the schema.yml file and include tests for uniqueness, not null, and relationships. Custom tests are SQL queries that check for specific conditions and can be defined as standalone .sql files.

Q3: What are incremental models in DBT, and when should you use them?

A3: Incremental models in DBT are used to build models that process only new or changed data since the last run, rather than rebuilding the entire model from scratch. They are useful for large datasets where a full refresh would be time-consuming and resource-intensive.

Common Mistakes to Avoid

  1. Ignoring the Official Documentation: The official DBT documentation is crucial for understanding the core services and features of DBT. Don’t overlook it.
  2. Lack of Practical Experience: Theory alone won’t suffice. Ensure you get hands-on experience with DBT to understand how it works in practice.
  3. Not Engaging with the Community: The DBT community is a valuable resource for tips, advice, and support. Engage with it regularly to enhance your learning.
