🟦 1. Database Connection & SQL Queries

The project begins by connecting to a SQLite database containing e-commerce tables such as:

  • customers
  • orders
  • order_items
  • products
  • payments
  • sellers

Using SQL, the project performs:

  • Table exploration
  • Joins across multiple tables
  • Data aggregation
  • Category-wise and state-wise summaries
  • Payment-level analysis

Example SQL tasks include:

  • Total sales by product category
  • Number of customers by state
  • Total payment value per order
  • Most ordered product categories

These queries help extract only the required data, reducing the workload on Python.


🟦 2. Data Transformation using Pandas

After SQL extraction, the data is loaded into Pandas DataFrames for:

  • Data cleaning
  • Column renaming
  • Type conversions
  • Sorting and grouping
  • Preparing the final dataset for visualization

Pandas ensures smooth transitions between raw SQL output and readable analytics tables.


🟦 3. Data Visualization using Matplotlib

Visual analytics are created for better insight interpretation. Some visuals include:

  • Bar chart of customer count by state
  • Bar chart of sales by product category
  • Payment distribution charts
  • Analysis of order-item relationships

These visualizations give stakeholders a quick understanding of:

  • Which states have the most customers
  • Which product categories generate the highest revenue
  • How payments contribute to overall sales

Each chart helps answer real business questions.


🟦 4. Insights Generated

The notebook identifies patterns such as:

  • Top-performing product categories
  • Regions with maximum customer concentration
  • Payment values and methods used
  • Sales contribution by category

These insights can be used for:

  • Marketing strategy
  • Inventory planning
  • Product recommendations
  • Regional expansion opportunities

πŸ—‚ Dataset Structure

The analysis uses multiple relational tables, each representing an important part of the e-commerce business flow:

Table Description
customers Customer information including customer location
orders Order-level data such as order ID and order status
order_items Individual product items associated with each order
products Product details including product category
payments Payment information for each order
sellers Information about sellers in the marketplace

Using SQL, these tables are joined and analyzed collectively.


🎯 Purpose of the Project

This project demonstrates:

  • Efficient data extraction from relational databases
  • Strong SQL query design
  • Professional Python data analysis practices
  • Visualization & insight generation
  • End-to-end analytics workflow used in real companies

It showcases the skills required for:

  • Data Analyst
  • Business Analyst
  • Data Science foundations
  • SQL + Python analytics roles

πŸš€ Why This Project Is Useful

This E-commerce analysis project helps you practice:

  • SQL joins, group by, aggregations
  • Converting SQL results into Pandas DataFrames
  • Creating charts with Matplotlib
  • Extracting business insights
  • Working with multi-table datasets

The skills demonstrated here are the same used in real analytic dashboards and BI systems.


πŸ“ˆ Conclusion

This project provides a complete analysis pipeline using SQL and Python to answer critical business questions in the e-commerce domain. It highlights how structured data can be transformed into powerful insights that help in business decision-making, optimization, and understanding customer habits.
