How do Data Engineers combine data from multiple sources?
The question is about Data Analysis .
Data Engineers use ETL pipelines to collect and merge data from various sources, clean it, and convert it into a standard format. They might employ tools like Apache NiFi, Talend, or custom scripts to automate data extraction and processing. They also perform mapping, deduplication, and normalisation. APIs, databases, and cloud services help integrate both structured and unstructured data for analysis.
