It's built using the best practices in data engineering and analytics\n\n##  Data Architecture\n\nThis project follows the Medallion Architecture, organizing data into three layers:\n\n1. **Bronze** Layer: Stores raw data directly from source systems. In this project, data is ingested from CSV files into a SQL Server database\n2. **Silver Layer**: Performs data cleansing, standardization, and normalization, ensure the data is structured and ready for analysis\n3. **Gold Layer**: Contains business ready data modeled into star schema, optimized for reporting and analytics\n\n## Project Overview\nThis project involves:\n1. **Data Architecture**: Designing a modern data warehouse using medallion architecture Bronze, Silver, and Gold layers\n2. **ETL Pipelines**: Extracting, transforming, and loading data from source systems into the warehouse\n3. **Data Modeling**: Develop fact and dimension tables optimized for analytical queries\n4. **Reporting \u0026 Analytics**: Creating SQL-based reports and dashboards for actionable insights\n\n## Project Requirements\n#### Building the Data Warehouse ####\n#### Objective ####\nDevelop a modern data warehouse using SQL Server to consolidate sales data, enabling analytical reporting and informed decision-making\n\n#### Specifications ####\n#### Data Pipeline Overview  ####\n\n- **Data Sources**: Import data from two source systems (**ERP** and **CRM**) provided as CSV files  \n- **Data Quality**: Cleaning and resolve data quality issues before analysis\n- **Integration**: Combine both sources into a single, user-friendly data model optimized for analytical queries\n- **Scope**: Focus on the latest dataset only, historization of data is not required\n- **Documentation**: Provide clear documentation of the data model\n\n  ![image](https://github.com/user-attachments/assets/ae785fa6-f5f7-4148-bfae-dcd17c91c0c9)\n\n\n## BI: Analytics \u0026 Reporting\n#### Objective ####\nDevelop SQL-based analytics to deliver detailed insights into:\n- **Customer Behavior**  \n- **Performance of Product**  \n- **Sales Trends**\n\nThese insights give the stakeholders with key business metrics, enabling strategic decision making\n\n##  License\nThis project is licensed under the MIT License.
