What is Data Engineering?

Data Engineering is the process of designing, developing and maintaining systems that collect, process, transform, store and distribute data.

A Data Engineer works behind the scenes to make data available for analysts, data scientists, business intelligence teams and machine learning applications.

For example, imagine an e-commerce company receiving thousands of orders every hour.

The company may need to collect:

• Customer information
• Product information
• Order details
• Payment information
• Website activity
• Delivery information

All this information may come from different systems.

A Data Engineer creates pipelines that collect the information, clean it, transform it and store it in appropriate data platforms.

The processed data can then be used by:

• Data Analysts
• Data Scientists
• Business Intelligence teams
• Machine Learning Engineers
• Business teams

Therefore, Data Engineering forms an important foundation for modern data-driven organizations.

Why is Data Engineering Important?

Businesses today generate huge amounts of information every day.
