Data Engineering & Data Analytics

Course Overview:

Python & SQL Based Data Engineering & Analytics is designed to train technical freshers (B.Tech/MCA / BCA) in industry-oriented Data Engineering and Data Analytics. The program focuses on practical implementations of data pipelines, database engineering, ETL workflows, and business intelligence systems aligned with current market requirements.
Students will gain hands-on experience in data processing, warehouse design, reporting systems, and analytics dashboards, while understanding how modern AI systems depend on structured data pipelines.
