Roles in the Data Ecosystem
Data analytics involves different professionals working together to turn raw information into meaningful insights.
Each role plays a distinct part in this journey — and understanding these roles helps you see where you fit in.
Who Does What?
- A Data Analyst focuses on cleaning, analyzing, and visualizing data to answer business questions.
- A Data Scientist builds predictive models and algorithms, often using machine learning techniques.
- A Data Engineer builds the infrastructure — like databases and pipelines — that make data usable for others.
Collaboration Is Key
Although the roles differ, they often work together:
- Analysts interpret data for teams.
- Scientists build models that need clean, reliable inputs.
- Engineers ensure the data flows smoothly and is stored correctly.
You might start as an analyst but later develop engineering or modeling skills — the ecosystem is flexible.
