This course introduces the principles and practice of Extract-Transform-Load (ETL) systems—the backbone of modern data-driven operations. Learners begin by exploring database fundamentals, including schemas, tables, and source structures, and then examine how ETL pipelines move, clean, and shape data for reliable use across analytics and AI workflows. Building on this foundation, the course provides hands-on experience using Apache NiFi to construct visual, end-to-end ETL flows, guiding learners through essential tasks such as extracting raw data from multiple sources, applying meaningful transformations, enriching records, standardizing formats, and loading clean results into destination systems. Each module builds practical fluency: from understanding core ETL concepts, designing extract–transform–load pipelines, to applying automation, optimization, and AI-supported improvements.
This course is designed for beginners with an interest in data engineering and database management. Whether you're a new data analyst, aspiring data engineer, or anyone looking to understand the role of ETL in modern data workflows, this course will equip you with the knowledge and skills needed to build effective ETL systems.
No prior experience with ETL, programming, or advanced data science concepts is required. A basic understanding of databases, CSV files, and general data concepts will be helpful but is not mandatory.
By the end of the course, learners will design and optimize a complete ETL workflow and understand how modern teams integrate these pipelines into analytics platforms, operational dashboards, and machine-learning feature pipelines.
This module introduces learners to the foundations of ETL by explaining why reliable data movement begins with understanding databases, schemas, and source structures. Through a guided Apache NiFi walkthrough, learners learn how to open the workspace, connect to a database, inspect tables, and preview real data. The module builds a consistent, team-wide approach to exploring source data—laying the groundwork for accurate extraction, transformation, and loading in later modules.

Module 2•1 hour to complete
Module details
This module guides learners through the full ETL workflow by breaking it into its core stages—extract, transform, and load—and demonstrating how each step ensures data reliability. Through hands-on activities in Apache NiFi, learners build a simple end-to-end pipeline that pulls raw data, cleans and enriches it, and loads it into a structured destination. The module emphasizes consistency, automation, and validation so learners can design repeatable pipelines that support accurate analytics and downstream systems.

"When I need courses on topics that my university doesn't offer, Coursera is one of the best places to go."
Chaitanya A.
"Learning isn't just about being better at your job: it's so much more than that. Coursera allows me to learn without limits."
When will I have access to the lectures and assignments?
To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I purchase the Certificate?
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
Is financial aid available?
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
