elif-orm 0.7.1

//! # elif-orm: Database Layer for elif.rs
//!
//! Production-ready ORM with modular architecture featuring:
//! - Core database abstraction layer
//! - Query building and execution
//! - Model system with relationships
//! - Migration and schema management
//! - Factory system for testing
//! - Connection pool management
//!
//! ## New Modular Architecture
//!
//! The ORM is organized into 6 main domains:
//! - `backends/` - Database backend abstractions (PostgreSQL, etc.)
//! - `connection/` - Connection pool management and health monitoring
//! - `transactions/` - Transaction lifecycle and isolation management
//! - `query/` - Query building and execution
//! - `sql/` - SQL generation and security
//! - `models/` - Model traits and CRUD operations
//! - `relationships/` - Relationship system and loading
//! - `loading/` - Eager/lazy loading strategies
//! - `migrations/` - Schema migrations
//! - `factories/` - Model factories and test data
