3. SQL for Data Analysis
Data Storage
SQL is used to store and manage large amounts of structured
data efficiently.
Querying Data
SQL allows analysts to retrieve specific data using commands
like SELECT, JOIN, and WHERE.
Data Manipulation
With SQL, users can filter, aggregate, and transform datasets
for better insights.

4. Power BI for Data Visualization
Data Connection
Power BI allows integration with various data sources,
including SQL databases and cloud platforms.
Interactive Dashboards
Users can create visually rich and interactive dashboards to
track key performance metrics.
Data Transformation
Built-in tools help in cleaning and transforming raw data into
meaningful insights.

5. Tableau for Data Visualization
Drag-and-Drop Interface
Tableau provides an intuitive interface for building
visualizations without coding.
Advanced Analytics
Tableau enables users to apply statistical models, trend
analysis, and predictive analytics.
Collaboration & Sharing
Users can publish dashboards and collaborate through
Tableau Server or Tableau Online.

6. Python for Data Analysis
Data Processing
Python offers powerful libraries like Pandas and NumPy for
handling large datasets.
Visualization & Insights
Matplotlib and Seaborn help create meaningful charts and
graphs for analysis.
Machine Learning
Python integrates with machine learning frameworks like
Scikit-learn and TensorFlow for predictive analytics.

7. Which tool should
you use?
Each tool serves a
unique purpose—SQL
for querying, Power
BI/Tableau for
visualization, and
Python for advanced
analytics.
How to choose the
right tool?
The best tool depends
on the data source,
required
transformations, and
desired insights.
