Data is ingested from CSV Files into SQL Server Database. \u003cbr\u003e\n**2.Silver Layer:** This layer includes data cleansing, standardization, and normalization processes to prepare data for analysis. \u003cbr\u003e\n**3.Gold Layer:** Houses business-ready data modeled into a star schema required for reporting and analytics.\n\n# 📖 Project Overview\nThis project involves:\n\n**Data Architecture:** Designing a Modern Data Warehouse Using Medallion Architecture Bronze, Silver, and Gold layers.  \u003cbr\u003e\n**ETL Pipelines:** Extracting, transforming, and loading data from source systems into the warehouse.  \u003cbr\u003e\n**Data Modeling:** Developing fact and dimension tables optimized for analytical queries.  \u003cbr\u003e\n**Analytics \u0026 Reporting:** Creating SQL-based reports and dashboards for actionable insights. \u003cbr\u003e\n\n# 🚀 Project Requirements\n## Building the Data Warehouse (Data Engineering)\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# BI: Analytics \u0026 Reporting (Data Analysis)\n## Objective\nDevelop SQL-based analytics to deliver detailed insights into:\n\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.\n\n# 📂 Repository Structure\n\n```\nsql-data-warehouse-and-analytics-project/\n│\n├── Datasets/                           # Raw datasets used for the project (ERP and CRM data in csv)\n│\n├── Docs/                               # Project documentation and architecture details\n│   ├── etl.drawio                      # Draw.io file shows all different techniquies and methods of ETL\n│   ├── 1_Data_Architecture.png         # PNG file shows the project's architecture\n|   ├── 2_Integration_Model.png         \n│   ├── Data Catalog.md                 # Catalog of datasets, including field descriptions and metadata\n│   ├── 3_Data_Flow_Diagram.png         # PNG file for the data flow diagram\n│   ├── 4_Data_mart.png                 # PNG file for data models (star schema)\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|── EDA \u0026 Analysis Scripts/             # SQL scripts for EDA, query analysis and query reports\n|   ├──EDA_Analysis.sql                 # EDA analysis like database exploration, dimension exploration, date range exloration etc.\n|   ├──Advance_Analysis.sql             # Business analysis like change over time analysis, performance analysis, cumulative analysis etc. \n|   ├──report_customers.sql             # Business report placing importance on customer dimension\n|   ├──report_products.sql              # Business report placing importance on product dimension\n│\n├── README.md                           # Project overview\n\n```\n\n# Original Repository\n[Link Here](https://github.com/DataWithBaraa/sql-data-warehouse-project)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frumana-amin%2Fsql-data-warehouse-and-analytics-project","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frumana-amin%2Fsql-data-warehouse-and-analytics-project","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frumana-amin%2Fsql-data-warehouse-and-analytics-project/lists"}
