Summary
This comprehensive, beginner-friendly project guides users through building an end-to-end data engineering portfolio using AWS S3, Snowflake, and DBT, covering advanced concepts like metadata-driven pipelines and Slowly Changing Dimensions Type 2.
Key Points
- The project integrates Git and GitHub for version control, teaching essential commands for branching, committing, and merging changes to manage the codebase effectively.
- This comprehensive project guides users through building an industry-level data engineering portfolio using AWS S3, Snowflake, and DBT, suitable for both beginners and experienced professionals.
- DBT (Data Build Tool) is utilized to build the silver layer, focusing on modularized data transformations, advanced Jinja templating, and custom macros for reusability.
- The project introduces metadata-driven pipelines in the gold layer, demonstrating how to dynamically join multiple silver tables to create a "One Big Table" (OBT) using Jinja configurations.
- A star schema is constructed from the OBT, creating fact and dimension tables, with a deep dive into implementing Slowly Changing Dimensions (SCD) Type 2 using DBT snapshots.
- Participants will learn to set up free AWS and Snowflake accounts, then securely ingest data from S3 into Snowflake's bronze layer using IAM roles, file formats, and stages.
- Emphasis is placed on understanding DBT's underlying mechanisms, such as how it generates DDL/DML statements, and on practical troubleshooting skills for real-world development.
- Advanced DBT concepts covered include ephemeral models for temporary data transformations and overriding default schema generation for a cleaner data warehouse structure.
- Data quality is ensured through DBT singular tests, allowing users to define assertions and set severity levels (error or warning) for data validation.
