Description

Introduction

Data engineering plays a crucial role in the data science pipeline by ensuring that data is properly collected, processed, and stored in a way that allows data scientists to extract meaningful insights. While data scientists focus on building models and performing analyses, data engineers are responsible for making sure that the infrastructure, data pipelines, and storage solutions are in place to enable smooth and scalable data science workflows.

This course focuses on the essential skills and practices needed by data engineers to support data science initiatives. It covers the building of efficient data pipelines, managing large datasets, optimizing data flow, and ensuring data quality, security, and scalability—all critical components for bridging the gap between data engineering and data science.
