What is the difference between a data scientist and a data analyst?
A data analyst works with data to solve business problems using tools like SQL, R, or other programming languages; data visualization software; and statistical analysis.
Data analytics generally focuses on examining existing historical data to solve defined business problems and answer specific questions. Their work involves setting up dashboards, creating automated reports, and building data pipelines , and inform current decision-making.
A data scientist uses more advanced data techniques to make predictions about the future. They may come up with the questions their team should be asking and determine how to use data to answer them.
Data science goes beyond traditional analytics by using advanced techniques like machine learning and statistical modeling to predict future outcomes. Key differences include
- Technical depth: Data scientists require strong programming and math skills.
- Time orientation: Analytics focuses on describing and diagnosing past events, while data science predicts future outcomes and prescribes actions.
- Tools: Data scientists often use complex machine learning and AI frameworks.
Both data analysts and data scientists play valuable, complementary roles in organizations, with analysts laying the groundwork for data scientists to build upon.
In Cloud Technology : Data Analysts vs. Data Scientists
Data analysts typically use cloud services like:
- Cloud data warehouses: Amazon Redshift, Google BigQuery, Azure Synapse Analytics
- Business intelligence platforms: Tableau Online, Power BI Service, Looker, Google Data Studio
- ETL/ELT services: AWS Glue, Azure Data Factory, Google Cloud Data Fusion
- SQL query engines: Amazon Athena, Google BigQuery, Azure Cosmos DB
Data scientists leverage advanced cloud offerings. They build, train, and deploy predictive models using scalable cloud infrastructure.
- Machine learning platforms: AWS SageMaker, Azure Machine Learning, Google Vertex AI
- Container orchestration: Kubernetes (on AWS, Azure, Google Kubernetes Engine)
- Specialized computing resources: GPU/TPU instances (AWS EC2, Azure NCv3, Google Cloud AI Platform)
- MLOps tools: AWS SageMaker Model Monitor, Azure Machine Learning Model Monitoring, Google Vertex AI Model Monitoring
- Big data processing: Amazon EMR, Azure HDInsight, Google Cloud Dataproc, Databricks
