Differentiate - Data Analyst Data Engineer & Data Scientist

Data Analyst v/s Data Engineer v/s Data Scientists

Today's world runs completely on Data. So, There are several roles related data and most people get confused and have several misconception about them.

Data Analyst

The work of Data Analyst is to collect all the numeric and other kind of data and translate in the language (English) which everyone can understand easily. A data analyst is the one whose main aim is to collect the data and use it to help companies in making better business decisions.

Although the responsibility include as data analyst are data collection correlation analyses and reporting.


Roadmap to Become Data Analyst

  • Earn bachelor degree in (CS/IT)
  • Statistics
  • Technical Skills
  • Data Handling, Data Cleaning & Modelling
  • Business and Reporting Skills

Skills Required

  • Google Analytics
  • Programming Knowledge

  • Reporting and Data Visualization
  • Data Acquisition &Maintenance
  • Data Cleaning
  • Pattern Identification and Analysis

Data Engineer

The Data Engineer is the one who develops, constructs tests and maintain the complete architecture of the large-scale processing system and prepared data for analytical or operational users. The work of Data Engineer includes “data piping” to put all the information together from different sources.

And, then the Data Engineer Integrated consolidated for the clean and structure it for more analytic. And it can be different or we can say varies from organization or companies to companies.
