Designed as a portfolio project, it highlights industry best practices in data engineering and analytics.\n\n---\n## 🏗️ Data Architecture\n\nThe data architecture for this project follows Medallion Architecture **Bronze**, **Silver**, and **Gold** layers:\n![Data Architecture](docs/data_architecture.png)\n\n1. **Bronze Layer**: Stores raw data as-is from the source systems. 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\n---\n## 📖 Project Overview\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🎯 This repository is an excellent resource for professionals and students looking to showcase expertise in:\n- SQL Development\n- Data Architect\n- Data Engineering  \n- ETL Pipeline Developer  \n- Data Modeling  \n- Data Analytics  \n\n---\n\n## 🛠️ Important Links \u0026 Tools:\n\nEverything is for Free!\n- **[Datasets](datasets/):** Access to the project dataset (csv files).\n- **[SQL Server Express](https://www.microsoft.com/en-us/sql-server/sql-server-downloads):** Lightweight server for hosting your SQL database.\n- **[SQL Server Management Studio (SSMS)](https://learn.microsoft.com/en-us/sql/ssms/download-sql-server-management-studio-ssms?view=sql-server-ver16):** GUI for managing and interacting with databases.\n- **[Git Repository](https://github.com/):** Set up a GitHub account and repository to manage, version, and collaborate on your code efficiently.\n- **[DrawIO](https://www.drawio.com/):** Design data architecture, models, flows, and diagrams.\n- **[Notion](https://www.notion.com/templates/sql-data-warehouse-project):** Get the Project Template from Notion\n- **[Notion Project Steps](https://thankful-pangolin-2ca.notion.site/SQL-Data-Warehouse-Project-16ed041640ef80489667cfe2f380b269?pvs=4):** Access to All Project Phases and Tasks.\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### 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\nFor more details, refer to [docs/requirements.md](docs/requirements.md).\n\n## 📂 Repository Structure\n```\ndata-warehouse-project/\n│\n├── datasets/                           # Raw datasets used for the project (ERP and CRM data)\n│\n├── docs/                               # Project documentation and architecture details\n│   ├── etl.drawio                      # Draw.io file shows all different techniquies and methods of ETL\n│   ├── data_architecture.drawio        # Draw.io file shows the project's architecture\n│   ├── data_catalog.md                 # Catalog of datasets, including field descriptions and metadata\n│   ├── data_flow.drawio                # Draw.io file for the data flow diagram\n│   ├── data_models.drawio              # Draw.io file for data models (star schema)\n│   ├── naming-conventions.md           # Consistent naming guidelines for tables, columns, and files\n│\n├── scripts/                            # 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├── .gitignore                          # Files and directories to be ignored by Git\n└── requirements.txt                    # Dependencies and requirements for the project\n```\n---\n\n## ☕ Stay Connected\n\nLet's stay in touch!
