What is the Difference Between Data Engineering and Data Science?
Data Science is an interdisciplinary field that uses scientific methods, processes, algorithms, and systems to extract knowledge and insights from structured and unstructured data. It combines techniques from statistics, computer science, and domain-specific knowledge to analyse and interpret complex data sets. Data scientists use tools like Python, R, and machine learning libraries to manipulate data, build models, and visualise results.
On the other hand, data engineering focuses on designing, building, and maintaining the infrastructure and systems related to collecting, storing, and processing large volumes of data. Data engineers develop strong architectures to ensure data is accessible, reliable, and ready for analysis. They work with tools like Apache Hadoop, Apache Spark, SQL, and cloud platforms. Data engineers handle tasks like data pipeline creation, ETL processes, and database optimisation, ensuring data quality and integrity.
