Start with knowing the roles of a data engineer
In the later chapters, we will spend much of our time doing practical exercises to understand data engineering concepts. But before that, let’s quickly take a look at the data engineer role.
The job role is getting more and more popular now, but the terminology itself is relatively new compared to well-established job roles, such as accountant, lawyer, and doctor. The impact is that sometimes there is still a debate about what a data engineer should and shouldn’t do.
For example, if you came to a hospital and met a doctor, you know for sure that the doctor would do the following:
- Examine your condition.
- Make a diagnosis of your health issues.
- Prescribe medicine.
The doctor wouldn’t do the following:
- Clean the hospital.
- Make the medicine.
- Manage hospital administration.
It’s clear, and it applies to most well-established job roles. But how about data engineers...
