Data Engineering is like a builder who builds a house. The house in this example is a computer system, and the builder is the data engineer. They put all the pieces together to make sure the system can store, process and analyze data. The data engineer makes sure everything is connected and working properly. They also create the rules and processes that control how data is used, stored and shared. It’s their job to make sure the system is secure, efficient, and most importantly, helpful to people who use it.
