Database Integration in TuskLang - Bash Guide

🗄️ Revolutionary Database Configuration

Database integration in TuskLang transforms your configuration files into intelligent data management systems. No more separate database configurations or complex connection management - everything lives in your TuskLang configuration with dynamic queries, automatic connection pooling, and intelligent data caching.

> "We don't bow to any king" - TuskLang database integration breaks free from traditional database constraints and brings modern data capabilities to your Bash applications.

🚀 Core Database Directives

Basic Database Setup

#database: postgresql              # Database type
#db-type: postgresql               # Alternative syntax
#db-host: localhost                # Database host
#db-port: 5432                     # Database port
#db-name: myapp                    # Database name
#db-user: myuser                   # Database user
#db-password: mypassword           # Database password

Advanced Database Configuration

#db-pool-size: 10                  # Connection pool size
#db-timeout: 30                    # Connection timeout
#db-ssl: true                      # Enable SSL
#db-migrations: true               # Enable migrations
#db-backup: true                   # Enable backups
#db-monitoring: true               # Enable monitoring

🚨 Troubleshooting Database Integration

Common Issues and Solutions

1. Connection Issues
