• Macros: Reusable blocks of SQL code, enhancing efficiency and consistency.
• Tests: Assertions that verify data quality and consistency.
• Sources: Defining the raw data sources that dbt will transform.
• dbt CLI (Command Line Interface): The tool used to interact with dbt.

2. Types of dbt Worksheets:

Worksheets can be tailored to different skill levels and focus areas:

• Beginner: Focus on basic SQL queries, understanding dbt model structure, and simple data transformations.
• Intermediate: Introduce macros, more complex SQL joins and window functions, and basic testing.
• Advanced: Cover advanced macro development, complex data modeling scenarios, implementing comprehensive testing strategies, and incorporating CI/CD pipelines.

3. Designing Effective Worksheets:

Effective worksheets should be:

• Clear and Concise: Use simple language and avoid ambiguity.
• Well-Structured: Organize exercises logically, progressing from simple to complex.
• Relevant: Use real-world scenarios and data examples.
• Graded Difficulty: Start with easier tasks and gradually increase the complexity.
• Space for Answers: Provide sufficient space for users to write their SQL code and answers.
• Solution Key (Optional): Include a separate answer key for self-assessment.

4. Example Worksheets:

(Beginner Worksheet: SQL Fundamentals)

Exercise 1: Write a SQL query to select the names and ages of all users from the 'users' table where age is greater than 25.

Exercise 2: Write a SQL query to calculate the average age of all users in the 'users' table.

Exercise 3: Write a SQL query to count the number of users in the 'users' table who live in 'New York'.

(Intermediate Worksheet: dbt Models and Macros)

Exercise 1: Create a dbt model that calculates the total revenue for each product category from a 'sales' table. Use a macro to handle date formatting consistently.
