Technology Stack¶

Data Architecture Layers¶

Bronze Layer (Raw Data)¶

• Purpose: Raw data ingestion and storage
• Format: Delta Lake with schema evolution
• Retention: 90 days hot, 2 years cold
• Processing: Minimal transformation, deduplication

Silver Layer (Cleansed Data)¶

• Purpose: Validated and enriched data
• Format: Delta Lake with enforced schema
• Quality: Data quality checks, validation rules
• Processing: Cleaning, normalization, enrichment

Gold Layer (Business Data)¶

• Purpose: Business-ready aggregated datasets
• Format: Delta Lake optimized for queries
• Model: Star/snowflake schemas
• Access: Direct Lake from Power BI

🚀 Quick Start¶

Prerequisites¶

• ✅ Azure subscription with Owner/Contributor access
• ✅ Azure Databricks workspace (Premium tier)
• ✅ Power BI Premium capacity (P1 minimum)
• ✅ Azure DevOps or GitHub for CI/CD
• ✅ Confluent Cloud account (optional)

Deployment Steps¶

1️⃣ Infrastructure Setup¶

# Clone repository
git clone https://github.com/your-org/azure-realtime-analytics.git
cd azure-realtime-analytics

# Deploy infrastructure
az deployment sub create \
  --location eastus \
  --template-file infrastructure/main.bicep \
  --parameters @infrastructure/parameters.json

2️⃣ Databricks Configuration¶

# Configure Databricks workspace
databricks configure --token

# Deploy notebooks
databricks workspace import_dir \
  ./notebooks /Shared/RealTimeAnalytics

# Create clusters
databricks clusters create --json-file cluster-config.json

3️⃣ Data Pipeline Setup¶

-- Create catalog and schemas
CREATE CATALOG IF NOT EXISTS realtime_analytics;
USE CATALOG realtime_analytics;

CREATE SCHEMA IF NOT EXISTS bronze;
CREATE SCHEMA IF NOT EXISTS silver;
CREATE SCHEMA IF NOT EXISTS gold;

-- Create streaming tables
CREATE OR REPLACE TABLE bronze.events (
  event_id STRING,
  event_time TIMESTAMP,
  event_data STRING
) USING DELTA;

4️⃣ Power BI Integration¶

1. Open Power BI Desktop
2. Get Data → Azure → Azure Databricks
3. Enter workspace URL and credentials
4. Select Direct Lake mode
5. Choose gold layer tables
6. Build reports and dashboards
