🚀 Initial Implementation of Database Comparison Tool

This PR introduces a comprehensive database comparison tool built with Tauri, React, TypeScript, and Node.js.

✨ Features

• 🖥️ Desktop Application: Cross-platform desktop app built with Tauri
• 🔍 Schema Comparison: Compare tables, columns, indexes, foreign keys, views, procedures, and functions
• 📊 Data Comparison: Compare row counts and detect data mismatches
• 🔌 Plugin System: Extensible architecture for adding new database drivers
• 🛡️ Windows Authentication: Built-in support for MS SQL Server with Windows auth
• ⚡ Performance: Rust backend with Node.js sidecar for optimal performance

🏗️ Architecture

• Frontend: React + TypeScript + Tailwind CSS
• Backend: Tauri (Rust) + Node.js sidecar
• Database Drivers: Plugin-based architecture
• Communication: Tauri commands + REST API

🗄️ Database Support

Built-in Support

• ✅ Microsoft SQL Server (with Windows Authentication)

Plugin System Ready

• 🔄 MySQL (example plugin included)
• 🔄 PostgreSQL
• 🔄 SQLite
• 🔄 MongoDB

📁 What's Included

Core Application

• Complete Tauri desktop application setup
• React frontend with professional UI
• Node.js sidecar for database operations
• MS SQL Server driver with Windows auth support

Plugin System

• Plugin manager for loading custom database drivers
• Example MySQL plugin demonstrating the architecture
• Comprehensive plugin development documentation

Development Tools

• Development setup scripts
• TypeScript configuration throughout
• Comprehensive error handling and logging
• Professional code organization

🚀 Getting Started

1. Install dependencies:

   npm install
   cd sidecar && npm install && cd ..

2. Build and run:

   npm run sidecar:build
   npm run tauri:dev

3. Or use the development script:

   ./scripts/dev.sh

📋 Files Added

• Frontend: Complete React application with TypeScript
• Backend: Tauri Rust application with sidecar management
• Sidecar: Node.js service with database abstraction layer
• Plugins: Example MySQL plugin and plugin system
• Documentation: Comprehensive setup and plugin development guides
• Configuration: All necessary config files for development and build

🔧 Technical Details

• Type Safety: TypeScript throughout the entire stack
• Error Handling: Comprehensive error handling and user feedback
• Security: Secure credential handling and connection management
• Performance: Efficient database operations with connection pooling
• Extensibility: Well-designed plugin architecture for future expansion

🎯 Ready for Production

The MS SQL Server driver is production-ready with:

• Windows authentication support
• Connection pooling
• Comprehensive schema introspection
• Error handling and logging
• Security best practices

This implementation provides a solid foundation for database comparison with an extensible architecture that can easily accommodate additional database types through the plugin system.
