-- database/INSTALL_RBAC_METADATA.ddl

-- Execute in your Snowflake account as SYSADMIN role
USE ROLE SYSADMIN;
-- Paste and execute the DDL script

Step 2: Verify Installation

-- Confirm tables exist
SELECT COUNT(*) FROM ADW_CONTROL.audit.adw_rbac_metadata;
SELECT COUNT(*) FROM ADW_CONTROL.audit.adw_rbac_audit_log;

Step 3: Activate Virtual Environment

cd "C:\Users\atadas\Downloads\Eligibility\snowflake-role-based-access"
.venv\Scripts\Activate.ps1

Step 4: Start Streamlit

cd app

🔧 Common Operations

Add a New Permission

# Via Streamlit UI:
1. Go to "📝 Add Permission" page
2. Enter:
   - Database: ADW_PROD
   - Schema: ADS
   - Table: T_CUSTOMER
   - Role: ANALYST_ROLE
   - Permission: SELECT
   - Effective Start: Today
   - Description: "Read access to customer table"
3. Click "Add Permission"
# Automatically inserts into audit.adw_rbac_metadata

Review Audit Trail

# Via Streamlit UI:
1. Go to "🔍 Audit Log" page
2. Filter by:
   - Date range
   - Operation type
   - Status (Success/Failed)
   - User
3. View detailed operation information
# Reads from audit.adw_rbac_audit_log views

Check Active Permissions

# Via Streamlit UI:
1. Go to "📋 Metadata Management" page
2. View all active permissions
3. Filter by role/database as needed
# Queries vw_active_rbac_metadata view

Execute Grants

-- Via Snowflake:
-- After adding permissions to metadata table
CALL audit.USP_GRANT_RBAC(
    p_dry_run_flag => 'N'  -- Change to 'Y' for testing
);
-- Operation logged to audit.adw_rbac_audit_log

✅ Verification Checklist

After setup, verify:

-- Run this verification script:
SELECT 'Tables' as object_type, COUNT(*) as count
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = 'AUDIT'
  AND TABLE_NAME LIKE 'ADW_RBAC%'
UNION ALL
SELECT 'Views', COUNT(*)
FROM INFORMATION_SCHEMA.VIEWS
WHERE TABLE_SCHEMA = 'AUDIT'
  AND TABLE_NAME LIKE 'VW_%';

🐛 Troubleshooting

Issue: “streamlit: command not found”

Solution: Activate virtual environment first

.venv\Scripts\Activate.ps1

Issue: Streamlit connects but shows no data

Solution:

  1. Verify Snowflake connection credentials in config.ini
  2. Ensure tables are created in Snowflake
  3. Check SYSADMIN role has appropriate grants

Issue: “Permission denied” error in Snowflake

Solution: Execute INSTALL_RBAC_METADATA.ddl as SYSADMIN or ACCOUNTADMIN role

Issue: Indexes not visible

Solution: Verify DDL executed completely - check for errors in output

🎓 Key Concepts

Metadata-Driven Architecture

All permissions are stored as data in adw_rbac_metadata, not hard-coded. This allows:

Effective Dating

Permissions have start and end dates:

Audit Trail

Every operation is logged in adw_rbac_audit_log:

Status Tracking

🌟 Best Practices

  1. Always use Dry-Run First
    • Test permissions before real execution
    • Review SQL statements
    • Check for unintended impacts
  2. Document Permissions
    • Use description field
    • Include business justification
    • Reference internal ticketing system
  3. Review Audit Trail Regularly
    • Check for failed operations
    • Identify unusual patterns
    • Maintain compliance records
  4. Schedule Permission Expiration
    • Set effective_end_date for temporary access
    • System auto-deactivates expired permissions
    • Reduces privilege creep
  5. Use Bulk Operations
    • Grant multiple roles at once
    • Use CSV upload for large batches
    • More efficient than individual grants
