Frequently Asked Questions

What is the difference between a data engineer and a data analyst?
Data engineers build and maintain the infrastructure that makes data available — pipelines, warehouses, and ETL processes. Data analysts consume that data to generate insights and reports. Think of data engineers as the builders of the highway and analysts as the drivers. Both roles are essential but require different skill sets.
Do I need to know programming to become a data engineer?
Yes. Python and SQL are non-negotiable. Python is used for building pipelines, scripting ETL jobs, and working with frameworks like Apache Spark and Airflow. SQL is essential for querying, transforming, and managing data in warehouses. You should also be comfortable with version control (Git) and command-line tools.
Which cloud platform should I learn first — AWS or GCP?
AWS has the largest market share and more job listings, making it the safer first choice. However, GCP is dominant in companies that rely heavily on BigQuery and Google's data ecosystem. Start with AWS Data Engineer Associate, then add GCP Professional Data Engineer to become a multi-cloud candidate — this combination is highly valued by employers.
