What data-engineering-study-material does

The skill hands your agent a study guide for data engineering. It covers fundamentals and architecture patterns, ETL/ELT examples in Python with pandas and sqlalchemy, data quality checks through Great Expectations, an Apache Airflow DAG, plus streaming, batch processing, cloud platforms and orchestration.

It fires on triggers like explaining a data engineering concept or asking for interview preparation. The material is split into sections: fundamentals, tools, architectures, pipelines, cloud-platforms, streaming, batch-processing, data-quality, orchestration, interview-prep, projects.

This is a repository of text and code samples, not a package or a library. Running the examples needs Python and dependencies such as pandas, sqlalchemy, great_expectations, apache-airflow. If you want a tool that moves data on its own, this is not it — you read and work through the code yourself.

What it helps with

  • explain the difference between ETL and ELT with an example
  • build a learning pipeline from CSV into Postgres
  • write data quality checks for a table
  • prepare answers for a data engineering interview
  • walk through the structure of an Airflow DAG

Example prompts for the agent

  • explain how an ETL pipeline works and show me a Python example
  • what are the best practices for data quality checks?
  • help me prepare for a data engineering interview
