Welcome to the Data Warehouse and Analytics Project repository! This project presents an end-to-end data warehousing and analytics solution, covering everything from building the data warehouse to deriving meaningful insights. Developed as a portfolio project, it showcases industry best practices in data engineering and analytics.
The data architecture for this project follows Medallion Architecture Bronze, Silver, and Gold layers:

- Bronze Layer: Stores raw data as-is from the source systems. Data is ingested from CSV Files into SQL Server Database.
- Silver Layer: This layer includes data cleansing, standardization, and normalization processes to prepare data for analysis.
- Gold Layer: Houses business-ready data modeled into a star schema required for reporting and analytics.
This project involves:
- Data Architecture: Designing a Modern Data Warehouse Using Medallion Architecture Bronze, Silver, and Gold layers.
- ETL Pipelines: Extracting, transforming, and loading data from source systems into the warehouse.
- Data Modeling: Developing fact and dimension tables optimized for analytical queries.
- Analytics & Reporting: Creating SQL-based reports and dashboards for actionable insights.
Build a modern SQL Server–based data warehouse to unify sales data and support analytical reporting for better decision-making.
- Data Sources: Load data from ERP and CRM systems provided in CSV format.
- Data Quality: Clean and standardize data to address quality issues before analysis.
- Integration: Merge both sources into a single, user-friendly analytical data model.
- Scope: Work with the most recent data only; historical tracking is not required.
- Documentation: Create clear and structured documentation to support business users and analytics teams.
Develop SQL-based analytics to deliver detailed insights into:
- Customer Behavior
- Product Performance
- Sales Trends
These insights empower stakeholders with key business metrics, enabling strategic decision-making.
