What is difference between Data Sciecne & Machine Learning?

Question

Jk Malhotra · Answer

1. Data Science = The entire data pipeline
Data Science is a broad field focused on
extracting insights from data.
It includes:
Data collectionData cleaning and preprocessingExploratory data analysis (EDA)Statistical analysisData visualizationBuilding predictive models (which may include ML)Communicating insightsSupporting business decisions
Machine Learning is only one part of Data Science — specifically the part related to building predictive models.
2. Machine Learning = Building algorithms that learn from data
Machine Learning focuses on:
Designing and training prediction modelsOptimizing model performanceFeature engineeringDeployment considerations (ML pipelines)Understanding algorithms (regression, SVM, trees, neural networks, etc.)
ML is more technical, algorithm-heavy, and often requires deeper knowledge of:
Mathematics (linear algebra, calculus, probability)Optimization techniquesSoftware engineering concepts (for ML engineering roles)
You can be a Machine Learning specialist without doing data visualization, business analysis, or storytelling.
Where do we draw the line?
If your focus is on insights → Data Science
You are a Data Scientist if you mainly:
Clean dataExplore dataAnalyze and visualize trendsBuild simple to moderately complex modelsPresent actionable insights to stakeholders
If your focus is on building scalable prediction systems → ML Engineering / ML Specialist
You are an ML Engineer if you mainly:
Develop ML algorithmsOptimize them for performanceDeploy them into productionWork with big data toolsBuild ML pipelines (MLOps, GPUs, model optimization)
What if someone builds predictive models in Python?
This depends on context:
They are a Data Scientist if:
The goal is to understand data and support decisionsModels are part of broader analysisThey also work on cleaning, visualization, reporting
They are an ML Engineer if:
Their main job is to build the modelThey scale it for real-world useThey optimize accuracy, latency, memoryDeployment and monitoring matters
Same skills, different purpose.
Why the confusion?
Because in most beginner courses (including Uncodemy and others) both fields are taught together.
Also, smaller companies expect one person to handle all tasks — so the line becomes blurry.
