Data is ingested from CSV Files into SQL Server Database.\n2. **Silver Layer**: This layer includes data cleansing, standardization, and normalization processes to prepare data for analysis.\n3. **Gold Layer**: Houses business-ready data modeled into a star schema required for reporting and analytics.\n\nThis project involves:\n\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**: Developing fact and dimension tables optimized for analytical queries.\n4. **Analytics \u0026 Reporting**: Creating SQL-based reports and dashboards for actionable insights.\n\n---\n\n## 🚀 Project Requirements\n\n### Building the Data Warehouse (Data Engineering)\n\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 Sources**: Import data from two source systems (ERP and CRM) provided as CSV files.\n- **Data Quality**: Cleanse and resolve data quality issues prior to analysis.\n- **Integration**: Combine both sources into a single, user-friendly data model designed 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 to support both business stakeholders and analytics teams.\n\n---\n\n---\n\n### BI: Analytics \u0026 Reporting (Data Analysis)\n\n#### Objective\nDevelop SQL-based analytics to deliver detailed insights into:\n- **Customer Behavior**\n- **Product Performance**\n- **Sales Trends**\n\nThese insights empower stakeholders with key business metrics, enabling strategic decision-making.  \n\n## 📂 Repository Structure\n```\nsql_data_warehouse/                     # Root directory of the project\n│\n├── datasets/                           # Raw datasets used for the project (ERP and CRM data)\n│\n├── docs/                               # Project documentation and architecture details\n│\n├── scripts/advanced_analytics/         # Advanced analytics scripts for data analysis and reporting\n│\n├── scripts/exploratory_data_analysis/  # Exploratory data analysis scripts for initial data exploration\n│\n├── scripts/warehouse/                  # SQL scripts for ETL and transformations\n│   ├── bronze/                         # Scripts for extracting and loading raw data\n│   ├── silver/                         # Scripts for cleaning and transforming data\n│   ├── gold/                           # Scripts for creating analytical models\n│\n├── tests/                              # Test scripts and quality files\n│\n├── README.md                           # Project overview and instructions\n├── LICENSE                             # License information for the repository\n```\n---\n\n## 🛡️ License\n\nThis project is licensed under the [MIT License](LICENSE).
