+## 🏗️ Data Architecture
+
+The data architecture for this project follows Medallion Architecture **Bronze**, **Silver**, and **Gold** layers:
+![Data Architecture](docs/data_architecture.png)
+
+1. **Bronze Layer**: Stores raw data as-is from the source systems. Data is ingested in a batch process and retains its original form to serve as a source of truth.
+2. **Silver Layer**: Contains cleaned, standardized, and enriched data. This layer includes data cleansing, standardization, and normalization processes to prepare data for analysis.
+3. **Gold Layer**: Houses business-ready data modeled into a star schema. This layer integrates business logic and transformations required for reporting and analytics.
