SnowGuard Framework - Complete Implementation Summary

✅ What’s Been Updated

1. Streamlit Application (Updated)

File: app/main.py

Changes Made:

✅ Updated adw_rbac_metadata DataFrame to reference actual handbook table structure
✅ Added all metadata columns: record_created_by, record_create_ts, record_updated_by, record_updated_ts
✅ Updated adw_rbac_audit_log DataFrame with complete audit table schema
✅ Added sql_statement column to track actual SQL executed
✅ Added audit trail columns for comprehensive logging

Result: The Streamlit UI now accurately reflects the metadata table structure defined in RBAC_Framework_Handbook.md

2. Database DDL Scripts (Created)

Location: database/ folder

New Files:

INSTALL_RBAC_METADATA.ddl (Master Installation)

Complete setup script for all SnowGuard framework objects
Creates database ADW_CONTROL and schema audit
Includes sample data (commented out)
One-stop shop for complete installation

adw_rbac_metadata.ddl (Standalone)

Creates audit.adw_rbac_metadata table
Stores permission mappings between tables and roles
Includes 5 optimized indexes:
- Unique composite key index
- Database filtering
- Role-based queries
- Effective date range queries
- Status filtering
Includes view: vw_active_rbac_metadata

adw_rbac_audit_log.ddl (Standalone)

Creates audit.adw_rbac_audit_log table
Comprehensive audit trail of all operations
Includes 5 performance indexes
Includes 3 supporting views:
- vw_successful_rbac_operations - Success audit trail
- vw_failed_rbac_operations - Failure analysis
- vw_rbac_operations_summary - Daily statistics

README.md (Database Documentation)

4. Quick Start Instructions

Install SnowGuard Framework in Snowflake

-- 1. Copy contents of INSTALL_RBAC_METADATA.ddl
-- 2. Execute as SYSADMIN role in your Snowflake account
-- 3. Verify with:

SHOW TABLES IN SCHEMA ADW_CONTROL.audit;
SELECT * FROM ADW_CONTROL.audit.vw_active_rbac_metadata;

Start Streamlit Application

# From the snowflake-role-based-access directory
cd app

# Activate virtual environment (if not already active)
.venv\Scripts\Activate.ps1

# Run the Streamlit app
streamlit run main.py

The app will be available at: http://localhost:8501
