I don't have any idea about what is data science except that it's a programming field

let me write down what I've gotten today, Today I've learned about what is data science, along with, the difference between a data scientist, data engineer, data analyst and machine learning scientist.

I used to think these several work job titles are the same and there are no differences in real life, but you can give these titles another try.

Data Engineer Job

  1. Information architects

  2. Build data pipelines and storage solutions

  3. Maintain data access

this article the 1st of my journey to learn data science beside to help other people by share my journey, until now I've didn't face any problem or issues. but one day we will get it. this my journey to become software engineer or scientist(I've not chosen, yet)
