20 PIPELINE MODELS Python & SQL: Technical Applications in ETL, Automation, and Data Analysis
About this ebook
Build, test, and deliver data pipelines with real engineering. This book presents 20 functional pipeline models using Python and SQL, structured in modular chapters that cover everything from file and API ingestion to transformations with Pandas, validation, SQL persistence, orchestration with Airflow and Prefect, as well as integrations with Google Sheets, Power BI, and Kafka. Each model is designed for direct use in professional environments, with clear architecture, validated code, and detailed technical explanation.
Throughout the reading, the reader gains a systemic view of data flows, learns how to build with traceability and reliability, and masters the combined use of Python and SQL in ingestion, transformation, enrichment, and delivery projects. All pipelines are presented following the TECHWRITE 2.2-P standard structure, ensuring consistency, clarity, and reusability.
More than commands or tutorials, this work delivers applied engineering focused on automation, integration, and technical efficiency. It is a construction platform for data engineers, advanced analysts, system architects, and professionals who need to design modular flows with technical responsibility and measurable results.
If you are looking for a book that works as a technical manual, functional catalog, and operational system, this work is for you. With it, you not only learn — you execute. And you build with purpose.
